The Wahl DHS35 Series High Performance handheld infrared thermometers are advanced, easy to use models. The DHS35XT has specialized reflex sighting to enable readings from very small target areas.  Errors caused by the reflectance from walls and flames are minimized.

This model has an ultra-high temperature range of 800° to 3200°F (426° to 1760°C).  With precision ground mirrors and rare earth germanium filters, infrared energy is tightly focused on on the patented detector for accuracy of ± 0.5% of full scale (at 77°F, ±5°) and repeatability of ±3°F with 1°F / °C resolution. The DHS35XT does not measure through glass ports.

Aluminum housing is durable and long lasting, providing shielding against stray EMF from machinery and engines. Model is °F/°C Switchable with adjustable emissivity.  Narrow spectral range of 3.5 - 4.1 microns makes this unit the best choice for general purpose high temperature operations.

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.

The DHS35XT features an LCD screen.  Each unit comes with an AC adapter; choose 110V or 220V. This model does not have FM approval.  Comes with user manual, appropriate battery, carry case, and trigger lock.

The DHS35XT has a three year warranty covering defects in materials and workmanship.

NIST Calibration Available, sold separately.
