Measures Electrical Conductivity (EC), Temperature and Depth
Compact, Low Cost and Easy to Use.
Compact, Low Cost and Easy to Use.
Overview
A compact 3.4 cm diameter sensor that fits into tight spaces. The HYDROS 21 is an all-in-one instrument. It's a low-cost, durable, and easy-to-use tool for monitoring EC, temperature, and depth in both groundwater and surface water.
The HYDROS 21 is a water level sensor that is not only highly accurate but also designed to have low-complexity, low-maintenance, and low-cost.
The HYDROS 21 sensor provides accurate EC measurements with a range of 0 to 120 dS/m and a measuring depth of 10 m which makes it ideal for a broad range of applications.
