Product Specifications:
This product comes in two models: UT661A and UT661B. Both models include transmitters with a signal-line length of 20m in model A, and 30m in model B. They both deliver superior performance, able to measure distances (depths) greater than 50cm.
Their transmitters operate on a current that varies from 150~450mA (at a distance of 1cm). They are rechargeable, and the recharging current approximately ranges from 450~550mA. You can expect a decibel level of more than 93dB at 1cm distance and more than 75dB at 0.5m distance.
The Transmitter is equipped with a built-in lithium battery, with a powerful capacity of 3.7V1800mAh. The Receiver operates on a lithium battery BL-5C, which offers 3.7V 1120mAh of energy capacity. These superb batteries give an impressive usage time of about 10 hours.
This product is designed to work efficiently, even in harsh environments. It confidently operates in temperatures ranging between -10°C to 50°C (10~80%RH), and also withstands storage temperatures between -20°C to 50°C (10~70%RH).
Furthermore, this product can measure various pipe materials, including plastic and metal. The dimensions of the Transmitter are approximately 386mm x 303mm x 42mm, while the Receiver measures 385mm x 75mm x 44mm.
Considering weight, the Transmitter weighs 1.10KG, and the Receiver is much lighter at 0.23KG.
