The model TG58SA bimetal thermometer has been specifically designed for the high 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 external power (e.g. with mobile vessels), the TG58SA with case filling is particularly suitable.

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

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

The TG58SA in hygienic design can be used for CIP (cleaning in place) and SIP (sterilisation in place) and in wash-down areas. The measuring instrument can thus be cleaned reliably and time-efficiently.
Especially for SIP applications, the thermometer shows a high overtemperature resistance and thus ensures a safe temperature measurement.

Based on a third party verification, the model TG58SA corresponds to the 3-A Sanitary Standard.

A variety of 3.1 and 2.2 certificates are available for GMP-compliant documentation, such as a material certificate or the list of single measured values.
