UNI-T UT661D Series Pipeline Blockage Detectors

From the shop's description

UNI-T UT661D Series Pipeline Blockage Detectors The UNI-T UT661D series are specialized tools designed to assist technicians in identifying and locating blockages within pipelines. The unit consists of two main components: a transmitter that sends a signal wire down the pipe via a signal wire, and a receiver that detects the signal emitted by the transmitter. This setup allows the user to follow the signal aboveground and determine exactly where the blockage or obstruction is located inside the pipe. The device is engineered to handle various pipe materials including plastic (PVC) and metals (steel, iron), making it versatile across many scenarios. Its signal wire can extend deep into pipes up to 35 meters for the UT661D model while the receiver is capable of detecting the buried or enclosed transmitter through materials and soil up to around half a meter above the pipe. The design is meant for ease of use, with audible and visual cues to guide users to the blockage point. Built to operate in field conditions, the UT661D is portable and reasonably rugged, with features to help its usability in environments like utility corridors, floor slabs, or buried pipelines. Its batteries allow for extended use, and its signal and alert systems reduce the chance of error in detection. Overall, the UT661D series aims to simplify pipeline diagnostics, helping reduce guesswork, speed up detection, and improve repair response times.
