DHSA28 Series High Performance Heat Spy Infrared – Discontinued
**This item has been discontinued and replaced with the DHS40.**
**THIS SERIES HAS BEEN DISCONTINUED AND REPLACED WITH THE DHS40 SERIES**
The Wahl DHSA28 Series High Performance handheld infrared thermometers are advanced, easy to use models. This model has an ultra-high temperature range of 32° to 2500°F (0° to 1380°C). 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 ±3°F with 1°F / °C resolution. This series is specialized for measurement of glass gobs, heat treating, annealing, welding, and metal ingot operations. Please note these models will not measure through glass ports.
Aluminum housing is durable and long lasting, and each model is °F/°C Switchable with adjustable emissivity. The DHSA28 Series features an anti-reflective filter for accurate use in sunlight or strong light sources. This model can measure normal materials, including glass surfaces. Measurement with the DHSA28 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.
*If measuring high temperatures, the telescopic sighting option is recommended to maintain a safe distance from the target.*
All DHSA28 Series models feature LCD screens.
Each unit comes with an AC adapter; choose 110V or 220V.
The DHSA28 has a three year warranty covering defects in materials and workmanship.
NIST Calibration Available, sold separately.
