Sewer Video Inspection Camera GT230 | 5 Lenses | 5.5mm | Laser | 9 Levels

Sewer video inspection camera GT230 — the multifunctional Ultra HD system with five interchangeable lenses and patented technology for inspecting sewer pipes with diameters from 7mm to 800mm. With the 5.5mm lens that enters 7mm pipes, nine patented Cold LED brightness levels and a comparison laser included as standard on the 51mm lens, this sewer video inspection camera combines the widest diameter range in the Jiutai push rod lineup with patented optical and lighting technology, with advanced imported technology underlying the design.

The waterproof 10.1-inch DVR control unit, the 7mm fibreglass cable in lengths of 10–120m and the 6-hour battery life make the GT230 a sewer video inspection camera capable of operating independently of the power grid, in any field conditions — from indoor plumbing inspections in buildings to the verification of gas and oil pipes in industrial installations. Key Advantages of the GT230 Sewer Video Inspection Camera

• 5.5mm lens — enters 7mm pipes, an absolute record in the range: The GT230 is the only sewer video inspection camera in the Jiutai range equipped with a 5.5mm lens capable of inspecting pipes from 7mm inner diameter — the smallest diameter in the entire push rod and borescope series. Capillary service pipes, injection connections and precision installations with diameters of 7–15mm are inspectable without an industrial videoscope.

• Nine Cold LED brightness levels — patented: The Cold LED lighting system with 9 adjustable levels is a Jiutai-patented technology. The Cold LED cold light eliminates the thermal effect of conventional LEDs on surfaces with temperature-sensitive coatings and reduces operator eye strain during long sessions. Nine adjustment levels — versus the 3–6 of other systems — allow fine optimisation of brightness for each diameter and type of inner surface.

• Comparison/measurement laser included as standard on the 51mm lens: The 51mm panoramic lens comes with an integrated comparison laser as standard equipment — not as a cost-added option. The laser projects reference points onto the pipe surface for dimensional estimation of defects directly on the recorded image, without external measurement instruments.

• Centralizer included free of charge as a standard accessory: The simple centralizer for the 51mm lens is included in the standard delivery of the GT230, at no extra cost. The centralizer keeps the lens on the pipe axis in pipes with diameters much larger than the camera body, ensuring uniform documentation of the internal circumference.

• Five interchangeable lenses: 5.5 / 16 / 28 / 37 / 51mm: The set of five lenses includes the 28mm lens — unique in the Jiutai push rod range compared with the GT220 and GT-PTZ models — and the ultra-small 5.5mm lens. The 28mm lens covers the 30–80mm diameter zone where the 21mm lens is too small and the 37mm fits, but with a centralizer. Five lenses = five diameter ranges covered with a single platform.

• Patented optical zoom — more precise than digital zoom: The patented zoom optics deliver the close-up image without the resolution loss typical of digital zoom — defects documented at maximum zoom have the same clarity as the normal image, essential for quality technical reports.

• Waterproof 10.1-inch DVR control unit: The control unit with a Full HD 1920×1080 screen is waterproof and dust resistant — operable outdoors in the rain or in high-humidity environments without requiring additional protection. A wireless USB keyboard and a USB port for external storage complete a self-contained documentation system.

• 7mm fibreglass cable, 10–120m: The 7mm fibreglass push rod cable is more rigid than conventional metal cable, advancing in a controlled manner in long pipes with the footage counter displayed and saved directly on the video recording.

Technical Specifications — GT230 Sewer Video Inspection Camera

Applications — The GT230 Sewer Video Inspection Camera in Practice

A sewer video inspection camera from the GT230 series is the tool chosen by licensed installers and inspection firms that work daily on residential and commercial sewer networks with a wide range of diameters — from 7mm indoor connections to 800mm collectors — and who do not want to carry multiple systems for different diameters. The five lenses cover the entire range with a single platform; the AC/DC power supply eliminates dependence on a mains outlet in the field.

Gas installers, industrial oil network inspectors and pipe maintenance teams in civil construction use this sewer video inspection camera to document defects in drainage channels, service pipes and ventilation ducts with diameters of 7–800mm. The fibreglass cable and the 6-hour battery life allow complete inspection sessions without recharging and without cable fragility in pipes with complex routing. Explore the full range of Uzinex industrial equipment for video inspection solutions across all categories of pipes and installations.

Municipalities, building management companies and construction contractors use GT230-type sewer video inspection camera systems for the handover of new plumbing installations, the verification of blocked sewers and compliant documentation for intervention reports, in line with international standards for video inspection of pipes. The comparison laser included as standard on the 51mm lens completes the reports with dimensional data without additional equipment. How It Works — Workflow with the GT230

• Lens selection and off-grid power-up: The technician selects one of the five lenses for the diameter of the pipe to be inspected. The DVR unit powers up independently of the power grid — the 6-hour battery ensures complete mobility in the field without searching for a power outlet.

• Inserting the fibreglass cable into the pipe: The 7mm fibreglass cable is inserted through the trap, drain opening or accessible end. The footage counter displayed on screen automatically tracks the position of the lens in the pipe and saves the footage directly on the video recording.

• Inspection with 9 Cold LED levels: The operator adjusts the brightness to one of the 9 available levels for optimal illumination of the inspected diameter. This sewer video inspection camera — through Cold LED with 9 levels — eliminates the thermal effect and ensures uniform visibility on reflective surfaces or surfaces with light-absorbing deposits.

• Patented optical zoom and defect documentation: When a defect is identified, the patented optical zoom allows precise close-up without resolution loss. Photography and video recording are activated with the buttons on the keyboard or DVR. On the 51mm lens, the comparison laser projects the reference points for estimating the defect size.

• Real-time editing and report generation: The wireless USB keyboard allows defect annotation, entry of technical comments and editing of recordings on the DVR screen in real time. Data is saved on the internal SD card (32GB–1TB) or on any connected USB device.

Frequently Asked Questions about the GT230 Sewer Video Inspection Camera

What minimum pipe diameter can the GT230 inspect?

With the 5.5mm lens, the GT230 inspects pipes from 7mm inner diameter — the smallest accessible diameter in the category of push rod and borescope systems in the Jiutai range available at Uzinex. This allows the inspection of capillary service pipes, injection connections and precision installations with diameters of 7–20mm where no other push rod system in the range can enter. What are the mentioned patents and what practical advantage do they bring?

The GT230 has registered patents on three components: the lens's optical zoom (detailed images without resolution loss at zoom), the 9-level Cold LED lighting system (cold, uniform light, fine adjustment) and the wide-angle optics of the front lenses (a wider field of view than standard optics). These patents mean that this sewer video inspection camera cannot be directly replicated by unlicensed systems — optical and lighting quality that is verified and legally protected. Is the laser included as standard or must it be ordered separately?

The comparison and measurement laser is included as standard in the delivery of the 51mm lens — there is no extra cost. The simple centralizer is also included free of charge. This sets the GT230 apart from other systems in the range where the laser is optional. On the 5.5mm, 16mm, 28mm and 37mm lenses, the laser is not included — if your inspections require dimensional measurement at diameters smaller than 55mm, the UZINEX team can configure the suitable solution. How does the AC/DC compatibility work and in which situations does it matter?

The GT230 operates both from the internal 6-hour battery (DC mode) and from the power grid (AC mode). DC mode ensures complete mobility on sites without an outlet — inspections in pits, in the wilderness or in buildings without power work without interruption. AC mode allows sessions of unlimited duration when an outlet is available, without consuming the battery for indoor building work. How does the GT230 compare with the GT220 and GT-PTZ?

The GT230 brings 5 lenses (versus 4 on the GT220), the 5.5mm lens for 7mm (versus the 20mm minimum of the GT220), a standard laser on the 51mm, 9 patented Cold LED levels and a fibreglass cable — all with AC/DC power. The GT-PTZ has a more rigid GFRP cable, detailed per-lens optical specifications and an 8h battery — recommended for industrial NDT audits with strict protocol requirements. The GT230 is the choice for professionals who inspect a wide range of diameters daily (7–800mm) and make use of the 5.5mm lens, the standard laser and the advanced patented technology.
