TST90 Modular RTD thermometer

Field of application

The thermometer is mainly used in the chemical industry but also finds its use in other branches. The device is used for high-precision measurement of temperature
differences with matched sensor pairs. A variety of dimensions offers flexible application possibilities.

• Universally usable for thermal energy measurements

• Measuring range: -200 to +600 °C (-328 to 1112 °F)

• Sensors in matched pairs within the range:

  0 to 120 °C (±0.05 K)

  –40 to 0 °C (±0.1 K)

• Protection class: up to IP68
