1048_2B Phidget Temperature Sensor 4-Input, 1048_2B


Read up to four thermocouples via USB with this board to measure the temperature of four different objects.


The 1048 allows you to measure extreme temperatures with up to 4 thermocouples. It is great for measuring temperatures in enclosed spaces or in liquids. This Phidget connects to your computer via USB.

  • Connects J, K, E or T type thermocouple, choose the type in software and convert to degrees Celsius automatically
  • If you have other thermocouple types, you can open the channel in VoltageInput mode and convert it to Celsius manually.
Technical Details:
  • Connection check - API will throw an error if the thermocouple wire becomes disconnected or breaks
  • Measure from a distance - Thermocouples have been known to work with wire segments as long as 100m, while USB and other sensors suffer from voltage drops after 5 or 10m.
