Why so many Heat-Prober

®

Meters?

Meters are the basic component of a Heat-Prober System. Probes, no matter how well designed and constructed will not compensate if the wrong meter is chosen for the job. Wahl Heat-Probers are offered in three basic measurement types:

Platinum RTD

Platinum Resistance Temperature Detectors (RTD’s) are recognized as the most reliable standard for measuring temperature information. Platinum provides long-term stability, response and repeatability for use as a primary standard. It has a wide useful temperature range and can be used in varying conditions, making it ideal for many applications.

Thermocouple

Thermocouple portable temperature sensors have the advantage over other types due to their fast response, wide temperature range, and ruggedness. The sensors are small in size, versatile and convenient to use. An added advantage of thermocouple use is derived from their wide-spread availability and meter/probe compatibility.

Thermistor

Thermistor sensors offer excellent accuracy and long-term stability, but over a relatively narrow temperature range. Thermistors are generally used to measure moderate temperatures in applications demanding greater accuracy than thermocouples, but less demanding than Platinum RTD Thermometer

Systems.

Each type has advantages and characteristics described in the catalog sections to follow. Basically the differences center on accuracy, temperature range, type of display and price.

What is a Heat-Prober

®

?

Wahl pocket-sized digital Heat-Probers are complete, high performance portable temperature measurement systems. Wahl originated the systems approach to provide engineers, technicians and research scientists the high confidence required for “routinely critical” temperature measurement.

A Heat-Prober “system” consists of a meter and a sensing probe.

The Heat-Prober meter serves (by means of a microprocessor) to accurately interpret the temperature sensed by the probe, provide digital output and allow measurement options such as peak reading hold or maximum/minimum memory. The meter also contains the power (battery) to allow complete system portability.

Heat-Prober probes are designed to be interchangeable. This allows a meter/probe system to be formed with any number of probes for specific applications used interchangeably with the meter. More probes for additional applications or replacement probes may be purchased, or an additional or replacement meter can be utilized without replacing existing probes.

Accuracy

Because of the Heat-Prober meter’s microprocessor, the probe’s sensor can be linearized to yield maximum accuracy at all points within the measuring range. Probe design is also a large factor in accuracy. The ability to select a standard or custom probe specific to the task and constructed from superior materials, is a key in “system accuracy.”

Portability and Ruggedness

A Heat-Prober’s battery power and rugged compact design make them the perfect choice for service and maintenance technicians who must use their temperature measurement equipment on the move and in a variety of tough environments. Kits with userselected probes are available for many of the meters. Heat-

Probers store away in small spaces without special requirements.

Versatility

Wahl offers Heat-Prober meters utilizing platinum RTD,

Thermocouple and Thermistor technology. Many meters offer range, display and kit options. All meters have a full set of interchangeable probes carefully designed and built to perform specific measurement tasks. This approach allows Heat-Prober users maximum versatility in specifying, purchasing, utilizing and maintaining a temperature measuring system suited to their needs.

Cost Effectiveness

Buy meters and interchangeable probes specifically for your applications and needs. Replacement and additional probes can be purchased as required.

Service

Wahl maintains a complete calibration lab with NIST traceability.

This service allows your Heat-Prober meters, probes or systems to be calibrated at standard or user-specified points. Wahl also offers repair service for meters and probes.

392 Series Platinum

RTD Probes

Platinum resistance temperature detectors (RTD’s) are recognized worldwide by metrology laboratories as the most reliable standard for measuring and comparing temperature information. Platinum provides long-term stability and repeatability for use as a primary standard. It has a wide useful temperature range which makes it ideal for laboratory and industrial applications.

Our accurate, stable platinum sensors are housed in thin wall stainless steel shanks with low mass tips that don’t compete with the measured object. That’s why Wahl probes have fast response, and provide an accuracy of ±0.2°F at ice point, ±0.5% of reading thereafter.

Every probe is engineered to do a specific job in measuring surfaces, liquids, semi-solids or gasses. Each probe has a high quality, heatresistant Delrin ® handle, a coiled 5-foot cord and a snap-in connector that mates it solidly to our thermometer (exceptions noted in descriptions below).

Every probe is calibrated at two or three temperature points on NIST traceable secondary standards and tagged “Wahl Test Certified” with calibration data. You can order a NIST certificate with test data for meters and probes. See page 6.

For 392HP Probes, simply add “HP” after Model Number

Wahl Exclusive Surface Probes

For surface probes where it is necessary to bring the greatest amount of surface heat in direct contact with the sensor, a unique design developed for the U.S. Space Program is employed. The coil is bonded to a platinum base plate of low thermal resistance which contacts the measured surface. The platinum base, in turn, is bonded directly to a thin stainless steel, bell-shaped housing of low mass. Heat loss is impeded by high thermal resistance elements: stainless steel housing, shank and coil spring.

The coil spring in Wahl 121 and 145 surface probes provides automatic articulation of the tip for conformity and uniform contact with the surface being measured.

This is especially useful in blind recesses where contact measurements are made by “feel” instead of sight.

Type K Probes Type K Thermocouple Probes

Probes for High Performance

The quality of temperature measurement depends principally on the probe design as it relates to the object being measured. That’s why each of Wahl’s interchangeable thermocouple Type K probes is scientifically engineered to do a specific job.

Wahl thermocouple probes are designed for the fastest response possible depending upon use.

Each starts with the thermocouple junction, precision welded for virtually instant response. Then a stainless steel sheath is created with a thin wall for fast measurements or a thicker wall for heavy duty applications. Surface probe tips are Wahl-engineered to provide optimum contact with the least thermal load.

Thin wall 300 series stainless steel sheath results in fast probe response.

Rugged Delrin ® handle withstands high temperatures.

Portable probes have (except as noted) rugged Delrin ® handles, ANSI mini-connectors and 5-foot flexible compensated cables.

These probes are compatible and interchangeable for use with Wahl Heat-Prober Meters 2500/1370 series (page 10), TM410, and TM500 (page 11).

Calibration Traceable to NIST

All thermocouple probes are individually calibrated at two temperature points to the same NISTtraceable secondary standards and tagged with calibration data. Probes are calibrated with your purchased meter or with a factory maintained standard, so you get guaranteed precise temperature measurements in the harshest environments.

Flexible compensated cable takes abuse.

Type K ANSI miniconnector plugs solidly into thermocouple meters.

Look for the “Wahl Tested

Certified” calibration tag on every probe.
