First Use Experience

Our initial deployment of the WTW Conductivity Depth Armature 301982 took place on a moderately breezy afternoon by the banks of the Willow Creek reservoir. The goal was to establish baseline conductivity readings at various depths to assess the impact of recent agricultural runoff. The armature’s significant 198 ft (60 M) cable allowed us to easily reach our target depths of up to 40 meters, a task that would have been cumbersome with a shorter cable. We were impressed by how quickly the sensor stabilized, providing consistent conductivity and temperature data from the moment it was submerged. There were no immediate issues or surprises, just a smooth integration into our existing data logging system.

Extended Use & Reliability

After nearly six months of regular use, the armature continues to perform as if it were brand new. We’ve used it in everything from shallow, fast-flowing streams to deeper, more stagnant sections of our local lake. Its waterproof plug (IP 67) has proven its worth, remaining completely sealed even after accidental submersion during a hasty retrieval. The 4-electrode measuring cell design, which is a key feature, seems to resist fouling exceptionally well, minimizing the need for frequent cleaning. This durability is a stark contrast to some older models we’ve relied on, which would show noticeable wear and tear after just a few months of similar usage.

Breaking Down the Features of WTW Conductivity Depth Armature 301982
