HANDHELD INFRARED DHS-24, DHS-26, DHS-28  Heat Spy® Series

Digital Infrared Thermometers with NIST traceable accuracy are the most advanced, easy to use and durable I.R. Thermometers in the world. Their precision ground mirrors are protected by rare-earth germanium filters and tightly focus I.R. energy on the patented detector for accuracy as good as ±0.3% full scale with 1°F/°C resolution.

Temperature readings are updated a quick-fire 3 times per second on a unique red liquid crystal display – more readable than black. The entire body is cast of extruded aluminum which provides shielding against stray EMF from machinery and engines.

Factory Mutual Approved models for potentially explosive environments are also available. Use Heat Spy with confidence. Thousands have been in trouble-free service for 10 years or longer. Three-year warranty, factory recalibration and service.

DHS-24, 26, 28 Sighting Options

1. Enclosed Optical Sight . For most applications, the standard  enclosed optical sight provides target definition ad 4 ft. and 20 ft. with parallax  correction.
2. Switchable Laser Aiming 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.
3. Telescopic Sight. For long distances (20 to 100 ft.) or precise  aiming on small objects such as bolts, thick cable, tubing, forging and castings, The Heat  Spy "T" version telescopic sight provides sighting on the centerline of the  infrared optics.

DHS-24, 26 and 28 Display Modes:

1. Display options for LCD and LED. LCD is best for most uses. Select LED for low  light conditions.
2. Measured Temperature is updated 3 times per second on large LCD.
3. PEAK holds highest temperature and is especially useful in high temperature  scans.
4. TEST mode flashes room temperature to show Heat Spy is working properly.
5. BATT displays low battery. HLP flashes when instrument is out of specification.
6. ---- means measurement is over or under the range of the instrument.

Factory Mutual (FM) Approved models do not include the following Heat Spy features or options: F/C switch (order dedicated Fahrenheit or Celsius model); 1mV/degree output; rechargeable battery (use alkaline only); laser sighting.

All models include carrying case, spare battery, owners manual, trigger lock, AC adapter (specify 110 or 220VAC)

The new DHS-34 Heat Spy Portable infrared thermometer from Wahl focuses automatically for easier and more accurate spot temperature measurements.

You simply "point and press" the hand-held DHS-34A. No special skills or training are required. Readings are produced immediately to pinpoint potential trouble spots. With an optional View Finder Camera Kit you can take photographs through the lens for permanent records.

The DHS-34A presents a clearly defined target area and displays temperature in the view finder. An external LCD displays temperatures, mode, alarm, battery condition, and surface emissivity setting.

A standard model, DHS-34S, offers the same, compact, rugged construction and advanced performance without the auto focus feature. Data processing and printing capabilities can be added for both models with optional accessories.

HANDHELD INFRARED HSA-201 Heat Spy®

Heat Spy Telematic Scans Distant Target for Hot Spots & Easy to Use

Aim at any distant surface. The Telematic automatically reads zero. Squeeze the trigger and hold the first recording in memory. Sight the target area through the telescope and scan for hot spots. Then depress the Maxi-Temp switch to automatically lock in peak temperature observed. The meter indicates the exact temperature above or below the selected reference ambient source or selected target. The Telematic is available with a variety of scales: single range, dual range, °C and/or °F.

• Dial-face meter makes scanning for hot spots easy. The needle swing shows differential temperatures instantly.
• Maxi-Temp switch holds needle for precise temperature reading.
• Preferred by maintenance engineers for checking distant targets such as transmission lines, transformers and insulators. Special shielding from EMI interference.
• Ideal for preventive maintenance in refinery, steel and chemical processing. Search out hot spots on stacks, kilns, and reactors at convenient distance.
• Measures from 300 feet away. Only 1.8-inch target from 40 feet. High precision cross-hair telescopic sight.
• Gun stock mounted and balanced for comfort. Tripod fitting included.
• Emissivity control, Maxi-Temp™ peak hold, millivolt output to recorder and rugged carrying case are standard.
