Description

The model TG58SA bimetal thermometer has been specifically designed for the requirements of sanitary applications.

The purely mechanical temperature transmission functions via a bimetal coil in the stem. For applications that require a measurement needing no auxiliary power, e.g. with mobile vessels, the TG58SA with liquid (case) is particularly suitable.

On the back of the case, the zero point can be easily corrected.

The stem with its semi-spherical base, in conjunction with the aseptic process connections (e.g. clamp, VARINLINE ® ), enables a dead-space free connection to the process.

For further approvals, see page 7
