1. WATERPROOF PROBE: The tube detector is equipped with waterproof probes to cope with various environments, and the side panel lock detector has a long service life. 2. ABS MATERIAL: The detector is made of durable ABS material, which is resistant to impact, scratches and can be used for a long time. 3. BUZZER PROMPT: The tube detector can accurately locate the location of blockage and internal blockage of the pipeline, and remind you by buzzer sound. 4. WIDE APPLICATION: The wall mounted tube scanner can quickly locate any blockage, avoiding large-scale pipeline blockage. 5. 8 PROBE: The pipeline obstacle scanner has 8 probes that can be replaced to detect steel, iron and PVC pipes. Use as desired! Specification: Item Type: Wall Pipe Scanner. Mode: ZB CDY Material: ABS Signal receiver power supply mode: 1 x 9V 6F22 800mAh dry battery (built-in) Model generator power supply mode: 1 x 9V 6F22 800mAh dry battery (built-in) 2 x 9V 6F22 dry battery, each 800 mAh, will be transported with the goods (carried with the goods) Detection area: accurate to approx. 5cm / 2in Charging time: 4 hours Battery life: 7-15 days Product function: PVC pipes, iron pipes and other metal pipes can be detected. How to use: Usage: Please hold the handle well and operate according to the legend, rotate the wire spool, wind and unwind the wire 1. Thread the signal line and transmitter into the pipe until the signal line does not push forward, and the position of the probe is the locked position. 2. Turn on the power switch of the signal generator and the red indicator lights 3. Turn on the switch of the signal receiver and hold the signal receiver to detect along the approximate direction of the buried pipeline. If it approaches the horn of the probe receiver inside the pipeline, it makes a "dripping" noise, and the maximum noise is at the blocking point. Mark it, draw the signal line and open the ground to handle it. 4. If the test distance is shortened or the green light is on, it indicates that the battery is low. Please replace the battery (square 9V). If it is a charging model, please do so in a prompt manner. If the charger turns green, it indicates that it is fully charged. the receiver and transmitter simultaneously usually takes 4 hours to fully charge.
