  • Miniature Sensing Head Withstands Up to 120°C Ambient Temperature Without Cooling
  • Measurement Ranges From -20°C to 500°C
  • Choice of Outputs: 4-20 mA, 0-10 V DC, Type J or K Thermocouple
  • Right-Angled Cable Entry for Low-Profile Installations
  • Stainless Steel Sensing Head, Sealed to IP65
  • Fixed Emissivity 0.95 - Suitable for Measuring Most Non-Reflective Non-Metals, and Painted Surfaces

The PyroMiniOEM is a limited version of the popular Calex PyroMini but with many of the bells and whistles removed in order to provide a still powerfull infrared temperature measurement sensor at a very affordable price.

The PyroMini OEM non-contact infrared temperature sensors measure temperatures from -20°C to 500°C and provide a choice of analog outputs.

The miniature sensing head of the PyroMini OEM has a right-angled cable entry, allowing it to be installed where space is limited.

An ambient temperature rating of 0°C to 120°C allows use in applications such as dryers and curing machines where the air temperature is high.

Non-reflective, non-metallic materials such as paper, textiles, food, thick plastics, rubber, organic materials and painted surfaces can be measured accurately with the PyroMiniOEM.

Metal surfaces can be measured, provided they are painted or coated first.
