The M-THERMO3 16 is the most precise
temperature measurement module in its class
Measurement modules must withstand extreme requirements in order to deliver precise and valid results at all times. However, particularly if there is an external thermal influence on the measuring technology, this may have an undesirable effect on the measured values. Cutting-edge IPETRONIK technology reduces this to a minimum. Our latest development is the M-THERMO3 16 with nine supported thermocouple types. It is efficient, reliable and, above all, extremely precise. The module has an extremely compact design and offers unprecedented measuring accuracy in the segment of modular temperature recording – and it does so across all thermocouple types.
This graph shows the continuous development of temperature measurement inputs for our modules relative to the maximum deviation over the entire specified ambient temperature range (at a constant specified target temperature of 100 °C). This means that the M-THERMO3 16 is currently the most precise temperature measurement module in its class.
Further Applications
