YSI WaterLOG Submersible Pressure Transducer (H-3123)

YSI WaterLOG Submersible Pressure Transducer(H-3123)

Specifically designed to measure ground and surface water pressure, temperature and levels, the WaterLOG® Submersible Pressure Transducer (H-3123) can transmit data digitally over cable lengths of up to 304.8 meters(1000 feet). Its sleek stainless steel diaphragm and polyurethane vented cable, give the Submersible Pressure Transducer the durability it needs to survive rugged environments. Unique to the Submersible Pressure Transducer is the dry air moisture barrier system, providing atmospheric compensation with no on-site calibration required.
