The Hydronix Thermo-Tuff is a fast response, high precision, linear temperature sensor for use in industrial processes. Designed for measurement in bulk materials and mixing applications, it is especially suited for use in the harshest of environments such as concrete mixers and aggregate bins.

This sensor outclasses its rivals by taking advantage of high speed, high accuracy electronics, thermally isolated from their surroundings to achieve the fastest possible temperature response.

Typical applications for the Thermo-Tuff include sand, cement, concrete, asphalt and aggregates.
