Infrared temperature sensors for use between -20°C and 500°C

Datasheet View Catalog


The PyroCouple is a simple, robust infrared temperature sensor with a choice of analogue outputs. No complicated setup is required - just connect a temperature indicator and power supply, and instantly start taking measurements.
It is suitable for non-contact temperature measurement on most non-reflective non-metal surfaces, such as paper, thick plastics, asphalt, painted surfaces, food, rubber and organic materials, among many others.
Temperature range-20°C to 100°C (LT models)
0°C to 250°C (MT models)
0°C to 500°C (HT models)
