A range of low cost thermistor sensors comprising insertion, clamp-on, and outside air versions. A quick-release lid makes the TB/T.. range easy to install.

The insertion sensor may be used for duct or immersion purposes. It has a 6 mm diameter brass probe which is suitable for retrofit immersion applications and will fit most existing pockets (universal fitting kit option). Brass and 316 stainless steel pockets are available. A foam gasket is fitted, and an adjustable depth flange option is available for its use as a duct sensor, enabling the insertion depth to be adjusted.
