Product details
Product Introduction
Can be used to monitor water level and temperature changes in streams, lakes, wetlands, tidal areas, and groundwater. It has the advantages of high precision, easy use, and low price. It adopts the principle of pressure measurement, which eliminates bulky ventilation pipes and other equipment, does not require desiccants, reduces daily maintenance workload, has a compact size, and is easy to use. Meanwhile, U20 can also serve as an atmospheric pressure sensor for precision compensation of water level sensors.
This series of products has multiple models with different water level ranges and resolutions, with a maximum water level range of up to 76.5m. At the same time, there are two types of shells available for you to choose from: stainless steel and titanium alloy, which can meet your different needs. Titanium alloy casing is more suitable for high salinity and high corrosiveness areas such as wetlands, beaches, and oceans. The U20 is powered by a 3.6V lithium battery and has an extraordinary lifespan. Built in 64K memory, capable of storing approximately 21700 sets of pressure and temperature data.
