 AT SDI-12 temperature sensor

The AT submersible SDI-12 temperature sensor is designed for a variety of applications. The unit functions effectively in soil, shallow streams, surface and ground water. 

The AT sensor accurately measures temperatures in stilling wells, dams and aquaculture tanks where very long cable runs are often necessary (up to 300 ft.). Cable length does not affect accuracy performance.
