Smart Water/Air/Soil Temperature Sensor

The Smart Temp is a high precision digital temperature sensor that meets USGS guidelines. It features the ability to automatically sample temperature and calculate minimum, maximum, and average temperatures on a flexible time scale.

This sensor is ideal for high-accuracy readings in water, soil, and air. It features fully-potted components, robust PVC Type II housing, and marine-grade stainless steel, making the sensor ideal for harsh environments. Model 51163-300 is small enough to easily deploy through standard 1” (2.5 cm) PVC conduit with 8” (20.3 cm) factory bend corners. It also offers a loop hole which can be used to mount weights or pull the sensor through pipes or other small areas.

Model 51163-200 has a durable, marine-grade stainless steel tine for easy soil insertion.

SDI-12 output provides universal compatibility with any SDI-12- enabled data logger and low power applications, or use the standard SDI-12 command set over an RS-485 physical interface for applications that require long cable runs or many sensors.
