DHSA24 • DHSA26 • DHSA28 Series
Since Wahl introduced the FIRST digital portable infrared thermometer
thousands have been in use trouble-free for years.
With NIST traceable accuracy, Wahl’s DHSA24, DHSA26, DHSA28
Heat Spy® Infrared Thermometers are the most advanced, easy to
use and durable Infrareds in the world.
Their precision ground mirrors are protected by rare-earth germanium
filters, and tightly focus infrared energy on the patented detector for
accuracy as accurate as ±0.3% full scale with 1°F / °C resolution.
Rugged, cast and extruded aluminum case, provides shielding
against stray EMF from machinery and engines.
Temperature readings are updated 3 times per second on your
choice of standard LCD display, or LED for low light levels.
High reliability and higher accuracy than others.
Telescopic Sight
For long distances (20 to 100 feet) or
precise aiming on small objects such as
bolts, thick cable, tubing, forgings, and
castings. The Heat Spy “T” version telescopic sight provides sighting on the
centerline of the infrared optics.
Switchable Laser
Aiming Sight
Enclosed Optical
Sight
Highly visible narrow red light beam
pinpoints objects up to 100 feet away.
Good choice for locating hot spots and
for centering on targets.
For most applications, the
standard enclosed optical sight
provides target definition at 4 feet
and 20 feet with parallax correction.

DHS520B High Temperature Infrared
with Bluetooth® Communications
The Wahl DHS520B Series Heat Spy® models are general purpose, high
precision, portable infrared thermometers, designed for accurate high
temperature measurement in the range of 1022° to 5432°F (550° to 3000°C).
The measured temperature is displayed in four simultaneous modes:
continuous, peak, mean, and valley, with user selected mode for the
viewfinder display. The bright, back-lit external display panel indicates
status and configuration of thermometer.
Accurate sighting is ensured by the clear, wide angle (9°) field of view and
small, clearly defined (1/3°) measurement area. Focusing is variable from
1m to infinity, with close focus options available using auxiliary lenses. The
reflex optical system gives precise definition of target spot and simultaneous
backlit display of user selected values in the viewfinder.
Emissivity compensation is provided via the icon-based menu system. The
operating waveband has been carefully chosen to minimize errors due to
uncertainty in emissivity and the effects of atmospheric vapor components.
The DHS520B features
a 2-position trigger
which takes and stores
temperature readings.
