PyroCouple Simple Infrared Temperature Sensor with Analog Output

Regular price $172.00 Sale

  • Three Standard Temperature Ranges: 0°C to 250°C , -20°C to 100°C and 0°C to 500°C
  • Fixed emissivity setting: 0.95
  • 4-20 mA or  Type K thermocouple output options
  • Fast response with high stability
  • Stainless steel 316 housing
  • Sealed to IP65
  • Ideal for measuring non-reflective non-metals, or painted metal surfaces

The PyroCouple is a simple infrared temperature sensor with a choice of analog outputs. No complicated setup is required - just connect a temperature indicator and power supply, and instantly start taking measurements.    It is available with two standard temperature ranges and either  and industry standard 4-20mA output or K thermocouple output.

The PyroCouple is part of the the Calex Compact Series which is a range of high quality, low cost non-contact sensors that measure the temperature of inaccessible or moving objects and materials. They measure temperatures from -20°C to 500°C, accurately and consistently, with an outstanding response time of 240 ms. All models conform to industrial EMC standards.     

The PyroCouple is an ideal general-purpose sensor for a huge range of applications. It should only be used with reflective surfaces if they are painted first.

Since the outbreak of the Covid-19 pandemic, we have received a lot of interest in the use of our infrared temperature sensors for body temperature measurement.  These sensors are designed for industrial and laboratory surface temperature measurement.  They are not designed or certified for body temperature measurement or for medical use. Because of this IOThrifty does not warranty or guarantee their use in body temperature measurement applications

For measuring body temperature IOThrifty does offer these products:
