The Wahl DHSA26 Series High Performance handheld infrared thermometers are advanced, easy to use models.  This model has the same features of the DHSA24 series, but with a wider temperature range of 0° to 2000°F (-20° to 1000°C).  For ultra-high temperature range option up to 2500°F, see the DHSA28 Series.  With precision ground mirrors and rare earth germanium filters, infrared energy is tightly focused on on the patented detector for accuracy of ± 0.3% of full scale (at 77°F, ±5°) and repeatability of ±1°F with 1°F / °C resolution.

Aluminum housing is durable and long lasting, and each model is °F/°C Switchable with adjustable emissivity.  The DHSA26 Series features an anti-reflective filter for accurate use in sunlight or strong light sources.  This model can measure normal materials, including glass surfaces.  Please note these models will not measure through glass.  Measurement with the DHSA26 is not affected by IR heaters, carbon dioxide, or water vapor.

Choose the best sighting option for your application:

  • Enclosed optical sight is appropriate for most applications and provides target definition at 4 feet and 20 feet with parallax correction.
  • Telescopic sight is on the centerline of the infrared optics and is appropriate for long distances (20 to 100 feet), or for precise aiming on small objects like bolts, thick cable, tubing, forgings, castings, and more.
  • Switchable laser aiming sight is a highly visible narrow red light beam used to pinpoint objects up to 100 feet away.
    • 1mW is best for indoor use.
    • 5mW is useful in bright light or outdoor conditions.

Two screen options are available:

  • LCD screen is appropriate for most applications.
  • LED screen is easily readable in low light conditions.

Comes with user manual, appropriate battery, carry case, trigger lock and AC adapter; choose 110V or 220V.

The DHSA26 has a three year warranty covering defects in materials and workmanship.

NIST Calibration Available, sold separately.
