Product Description
The Geolux HydroTemp sensor comes as a single sensor or a multi-sensor array version for immersion into the water or soil to measure temperature in a single or multiple depths. Both variants have standard RS-485 Modbus and SDI-12 interfaces for easy integration with Geolux and third-party dataloggers. It is possible to connect up to 16 sensors in the multi-depth configuration with customizable distance between the sensors. The HydroTemp sensor has a high accuracy of 0.1 °C and a resolution of 0.01 °C for temperatures ranging from -20 °C to +70 °C, and a fast temperature change response due to the aluminum enclosure.
