The TN700MT thermometer
offers high precision measurements to an accuracy of +/-0.01°C or better (when used with ITS-90
Pt100 sensor) with resolution at 0.01°C (over the entire range -180 to
+650°C) or 0.001°C (optionally). It is mounted in 2U-19” rack case and provides
a linearized analog output (4/20mA for +20/+80°C).
Also, tests at 5 and 50°C are possible thanks to integrated very high
simulation resistances (55ppm max./year). TN700MT
also features an isolated communication interface with JBUS protocol.
