Handheld pipe inspection camera GT31DV — the fully portable system for the visual inspection of pipes and tubes with diameters of 10–200mm, designed to be held and operated with a single hand, with no separate control unit, no power cable and no external support. The 7-inch IPS touch screen, the cable from 5m and the 2.5-hour battery make the GT31DV the most compact handheld pipe inspection camera in the Jiutai range — the optimal solution for quick checks of traps, blocked drains and 10–150mm indoor pipes without carrying bulky equipment.
The spring body design of this handheld pipe inspection camera allows automatic traversal of the bends and tight spaces in indoor plumbing — the same proven spring mechanism of the Jiutai series, now integrated into the most compact format in the entire range. The wide-angle field of view of the 8mm, 16mm and 21mm cameras delivers the image directly on the 7-inch touch screen, with video recording at 30 frames/second and an automatic timestamp on every recording.
Key Advantages of the GT31DV Handheld Pipe Inspection Camera
• Fully handheld — the only single-hand-operated system in the range: The GT31DV is the only system in the entire Jiutai range in which the controller, the screen, the battery and the cable reel form a single handheld unit held in one hand. The technician inserts the cable into the pipe with the other hand and watches the live image on the 7-inch touch screen without setting down any component and without needing an assistant. This makes the GT31DV the fastest handheld pipe inspection camera to deploy in the entire range.
• Cable from 5m — quick checks without full unwinding: The minimum 5m cable length covers exactly the quick-check situations — blocked traps, sink or toilet drains, short indoor connections — where a system with a 20–120m cable requires unwinding the entire reel for a 2–3 minute inspection. The standard steel or fibreglass cable is configured on order from 5m to 30m.
• Spring body design — bends without jamming: The spring mechanism of the camera head automatically passes through the bends and changes of direction in indoor plumbing without jamming and without forcing the cable to bend. The 8mm and 16mm lenses with flexible body are designed specifically for small pipes with multiple bends — typical in the plumbing of apartments and houses.
• 7-inch IPS touch screen — full-view, operable with a finger: The full-viewing-angle IPS screen is operable with a finger, including with thin work gloves. The functions for photography, video, playback and timestamp are accessible directly on the touch screen without additional physical buttons — maximum simplicity for the technician holding the system with a single hand.
• Three interchangeable lenses: 8mm, 16mm, 21mm — wide-angle: The three wide-angle lenses cover diameters from 10mm to 200mm. The 8mm lens for small pipes of 10–25mm, the 16mm lens with a wide field of view for connections of 20–80mm and the 21mm lens for sewer pipes of 30–200mm. The wide-angle view delivers the complete image of the cross-section without angle adjustment — direct and rapid viewing.
• Video recording at 30 fps with automatic timestamp: The 30 frames/second rate ensures smooth recording of the cable's movement through the pipe — defects are captured without the frame "skipping" typical of systems with a lower capture rate. The time and date stamp on every recording ensures complete traceability of the inspection session.
• Steel or fibreglass cable — your choice: The GT31DV supports both a steel cable (more flexible, for tight bends) and a fibreglass cable (more rigid, for controlled advance in straight pipes). The choice is made when configuring the order according to the dominant type of installations inspected.
• IP67 waterproof — resistant to use in wet environments: The camera head is IP67 sealed — resistant to water jets and temporary immersion in traps and drains with residual water. This allows the inspection of pipes with partial water content without retracting the camera or stopping the session at first contact with the liquid in the pipe.

Applications — Where the GT31DV Handheld Pipe Inspection Camera Is Used
A handheld pipe inspection camera from the GT31DV series is the daily tool of plumbers who carry out quick checks of clogged traps, sink drains and toilet pipes in apartments and houses — 5–10 minute inspections where carrying a system with a 10-inch screen and a 40kg reel is not justified. The GT31DV is carried in the plumber's tool backpack and pulled out in 30 seconds for any emergency check without additional preparation.
The emergency services of building management companies, the rapid-response teams for drain clearing and the installers who work in studios, apartments and offices use this handheld pipe inspection camera for the rapid diagnosis of blockages before deciding on the type of intervention. The 5–30m cable covers all the typical sections within an apartment without unwinding metres of excess cable — the defining advantage of this handheld pipe inspection camera over systems with large reels. Explore the full range of Uzinex industrial equipment for inspection solutions across all categories of pipes and installations.
Technicians in the chemical and energy industries use GT31DV-type handheld pipe inspection camera systems for quick checks of compressed air, cooling and internal service pipes with diameters of 10–200mm — periodic preventive maintenance inspections that do not require complex formal documentation, but which identify blockages and defects before they cause failures in the production process, in line with international video inspection standards.
How It Works — Workflow with the GT31DV
• Power-up and lens selection: The technician powers on the handheld unit with a single button and selects the lens suited to the pipe diameter. The system is ready for inspection in under 30 seconds from being taken out of the tool backpack.
• Inserting the cable with spring body: The steel or fibreglass cable is inserted with one hand through the trap or drain opening. The spring body design automatically passes the bends — the lens reaches the defect zone without forcing or jamming at the changes of direction in the plumbing installation.
• Live monitoring on the 7-inch touch screen: With the other hand, the technician holds the handheld unit and watches the live wide-angle image. The footage counter displayed on the screen permanently indicates the depth at which the camera head is located in the pipe.
• Quick defect capture: When a blockage, deposit or structural defect is identified, the technician presses the capture button on the touch screen. Photographs and videos are saved automatically with the timestamp and footage on the recording.
• Retraction and reporting: The cable is retracted manually. The recordings are immediately available on this handheld pipe inspection camera for presenting the diagnosis to the client on the spot or for sending the files by email directly from the unit.
Frequently Asked Questions about the GT31DV Handheld Pipe Inspection Camera
What minimum and maximum diameter does the GT31DV inspect?
The GT31DV inspects pipes with diameters from 10mm to 200mm. The standard range stated by the manufacturer is 10–150mm; with the 21mm lens, pipes up to 200mm are accessible. This makes the GT31DV a handheld pipe inspection camera suitable for all standard indoor plumbing pipes — from the 10mm connections of heating installations to the 160–200mm sewer risers in residential buildings.
Why does the GT31DV have IP67 versus the IP68 of the other systems in the range?
IP67 guarantees protection against immersion at a maximum depth of 1m for 30 minutes — sufficient for the inspection of traps with a permanent water level and pipes with partial residual water. IP68 (standard on large crawler systems) allows continuous full immersion at great depths. For the typical applications of this handheld pipe inspection camera — indoor plumbing and apartment-block drains — IP67 is adequate. If your inspections involve fully flooded pipes at great depths, the Uzinex IP68 crawler range is the suitable solution.
How long is the cable and how do I choose the right length?
The GT31DV cable is configured from 5m to 30m. The 5m length covers the floor trap and sink connection of a standard apartment; 10m reaches the main sewer riser of a floor; 30m is the maximum length for more extensive inspections in commercial spaces or small industrial buildings. Compared with systems with a 60–120m cable that require full unwinding for any inspection, the 5m version is decisively faster to deploy.
Can the GT31DV replace a larger system for all inspections?
The GT31DV is complementary to the larger systems — it does not replace them for complex work. The GT230, GT220 or GT-PTZ are the correct choice for formal inspections with complete documentation, diameters of 400–800mm or routes of 60–120m. The GT31DV is the choice for quick diagnostic checks at 10–200mm, where deployment speed and handheld portability matter more than Full HD resolution or lens variety.
The camera records video at 30 fps — why does this specification matter?
30 frames per second is the standard rate for smooth video recording. On inspection cameras with lower rates (10–15 fps), the cable's movement through the pipe produces recordings with visible frame "skipping" — fast defects or lenses that briefly touch obstacles can be missed. At 30 fps, this handheld pipe inspection camera captures any visible defect along the route travelled, regardless of the cable's advance speed.
