Achieve low-cost measurements with an infrared thermosensor

This infrared thermosensor provides an accurate, stable and cost-effective way to measure the temperature of objects. It behaves just like a standard K-type thermocouple, which enables it to operate with any temperature controller or alarm unit.

  • Cost-effective infrared thermosensor
  • Contactless, meaning no deterioration, unlike thermocouples
  • 4 temperature ranges available: 10-70°C, 60-120°C, 115-165°C and 140-260°C
  • Response speed 300 ms
