K type thermocouple thermometer ST-90

Industrial digital portable thermocouple probe thermometer ST90 measures temperature over the range of – 200 to 1200, depends on probe type with resolution 0,1 °C from -49,9°C to 199,9°C ; 1°C outside.

Buttons on thermometer:

  • ON/OFF - turn on/turn off
  • HOLD - capture readings
  • ERASE - delete all saved readings
  • MAX - show maximal temperature
  • MIN - show minimal temperature


  • measuring in °C
  • display resolution 0,1°C from -49.9°C to 199,9°C, 1°C outside
  • display minimal and maximal temperature
  • low battery indication
  • high accuracy
  • universal mini therma K input/socket
  • hold function
  • simple and fast control

Thermocouple industrial thermometer works with K type thermocouple sensor probe. The device is equipped with Mini Therma K socket.

ST 90 is priced excluding probe. Termoprodukt offers interchangeable K type thermocouple probes and surface thermocouple probes.

Thermometer with interchangeable thermocouple probes ST 90 is made of ABS material protects it from mechanical damage, resistant to dust, dirt and water (IP 65).

Meat food processing industrial thermometer ST 90 features easy to read large display with min/max function, hold function and low battery indication.

Use a folic keyboard to turn on/off the device. This innovation protects the thermometer from fluids, e.g. from water, milk, fats, etc. ST-90 is feed by one 9V battery. Battery life equals ca. 500 hours.
