MESSKO MT-ST160

Pressure Switch

MT-ST160WR/TT/4/10M
The compact series consists of two types of temperature measuring instruments which are compact and complete in themselves, providing:

temperature measurement
display of the measured values
alarm messages
remote indication of the measured values
An extra advantage is that the temperature sensors are quite small and fit in all standard transformer thermometer pockets and wells.
