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.

Remote Sensor Systems
DIGI-STEM® is offered in a variety of configurations to measure process temperatures remotely located from the meter. Optional remote sensor cables are available with different stem configurations. Stems can be specified for a variety of process connections or interfaces, including different thermowell adapters,penetration probes and immersion probes.
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.

Humidity / Temperature Meters
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.

FM approval for use in hazardous environment
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 .
