Online Infrared Thermometer IRV

IRV Series

The IRV is an infrared thermometer with a separate miniature sensing head connected to an electronics box. The small short-wave head sits close to the hot target for non-contact measurement up to 1800°C, while the display and electronics stay in a cooler area for continuous monitoring at tight or hot points.

  • Separate miniature sensing head
  • Short-wave heads to 1800°C
  • Non-contact continuous monitoring
  • Backlit LCD electronics box
  • IP65 protection

    Frequently Asked Questions About This Product

    It is a two-piece non-contact thermometer where a small sensing head measures the target while a separate electronics box holds the display and outputs. The IRV head reads up to 1800°C in tight or hot locations.
    A separate head lets the small sensor sit close to a hot or tight target while the electronics box and display stay in a cooler, accessible area for continuous monitoring.
    The IRV covers from 0°C up to 1800°C across variants such as LTL, 1MS, 1MH, 2MS, 2MH, 2MV, 3ML and 3MS.
    The IRV provides a 4–20 mA analog output and RS485 Modbus RTU digital communication.
    Optical resolution depends on the variant: LTL is 15:1, 1M/2M is 66:1, 3ML is 10:1/20:1 and 3MS is 36:1.
    Yes. Optional accessories include an air purge collar, an air cooling jacket with integral air purge and a dual laser sighting tool.
    Users should check target temperature, head wavelength, spot size at distance, cable length, mounting and output requirement.
