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.

  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.

The accuracy and resolution of  Wahl's 700M Portable Thermistor Thermometer  make it an ideal instrument for  precision measurements in pipeline oil monitoring, chemical processing, biological testing  and research, and many other production, processing, and laboratory applications.

The handheld instrument provides a  resolution of 0.01°C/°F and an accuracy of ± 0.02°C within the temperature range of  -1.00 to +60.99°C (30 to 141.8°F). Accuracy is traceable to NIST, with an optional test  report for your quality assurance.

The system interchangeability and  accuracy of Wahl's 700M meter with both the LN0255 and LN0255A probes are shown in the  table at left. A system accuracy of ± 0.04°C is obtainable.

The microprocessor-based 700M is  barely a handful. It is only six inches in length and weighs 12 ounces. Measurements are  displayed on a bright red 0.33" LED, making it especially effective in indoor and  low-light conditions. A low drift range of 0.02 per year provides long-term accuracy.

The meter operates on an internal  battery pack with eight hours of continuous operation between charges.

The 700M is intrinsically safe and  Factory Mutual approved for hazardous environments. The meter design is similar to the  platinum meter Model 392M Heat Prober described .

DST200 with optional DSA392HP Dual  RTD Sensor in stem and connection on case. Shown with Platinum-RTD 392HP Meter used for  calibration. 

RTD or Thermocouple Output

Direct Connection: Wahl provides  optional DIGI-STEM with dual element temperature sensors in the stem for direct connection  to recorders and controllers. The primary sensor drives the local display while the  dedicated secondary sensor (RTD or thermocouple) provides access to a 3-or 4-wire RTD  circuit or a thermocouple system interface. The connecting port is 1/2"NPT.

In Situ Calibration: Specify option  DSA392 for in situ calibration of DIGI-STEM Model DST200 without removal from a  process. This instrument has an RTD as the secondary sensor, which allows single-point  calibration using Wahl's highly accurate platinum-RTD Heat Prober 392 Meter. This provides  the accuracy of a laboratory calibration and saves time and money,as well.

HTS30 High-speed System

  • Fast  response humidity sensor with 5-sec. time constant
  • 0 to  100% RH, -40 to +176°F
  • Not  affected by moisture condensation
  • Applications:  plant maintenance, air conditioning installation and maintenance, checking humidity levels  and temperature in process areas, measuring moisture content in pager

This handheld humidity instrument  system, comprised of a meter and probe, uses a thin film sensor for extremely fast  measurements. In operation, the film absorbs moisture, changing its capacitance proportional  to the relative humidity. The resulting linearized data is displayed in percent RH.

Simultaneous with the RH reading,  temperature is measured with 0.1° resolution over the -40 to +176°F temperature range.  Temperature measurements employ a high precision, 100 ohm, platinum RTD film sensor element  mounted in the same location as the humidity sensor. A plastic grid protects the sensors  against damage. Models are available with either Fahrenheit.

HTM34 Pocket-Size Meter

  • 6.25  × 2.24 × 1.06 in., 8.8oz.
  • 0 to  100% RH, -4 to +140°F or -20 to +60°C
  • 3-1/2  digit,3/4-in. high LCD readout
  • Hold  button provides measurement retention

Shirt pocket size for easy  portability, the HTM34 has a retractable probe that slides out of the meter case for  quick, easy checks of relative humidity and temperature in laboratory or industrial  environments
