Digital Probe Thermometers

Digital thermometers are the most commonly used temperature measuring instruments in the food industry. They are easier to read than glass thermometers, generally more accurate than the older dial-type thermometers based on bimetal coils, have a great range of specialized uses and applications and tend to have a much quicker response-time. Digital probe thermometers are generally of two types: thermocouple digital thermometers and thermistor digital thermometers.

Thermistor-based Digital Thermometers

Thermistor digitals generally have "built in" probes and sensors. They must be calibrated during the manufacturing process and so are not interchangeable. Thermocouple digitals, with some exceptions, can accept any matching category of probe (the two most common are K-type and T-type--these have different temperature ranges). We concentrate on K-type only, since this type spans all food application temperatures, and has more availability of probe options.

Accuracy can be very good with both types, but thermistor digitals are limited to the type of built-in probe they come with, and if the probe breaks, you have to buy a new thermometer.

Thermocouple digital thermometers are generally very predictable in their quality, and the response characteristics of their fitted probes is within a very narrow range. All QA stocks the highest quality thermocouple digital thermometers, so they can be used with high confidence.

Thermistor digitals are made worldwide, and can have variable quality, if not carefully checked. All QA performs checks of all of their thermistor-based products to ensure that their customers are getting products of excellent quality. Our line of thermistor products represents the very best available at the price.

Thermistor Digital Thermometers

AQA 4500 Waterproof Thermometer

        $24.50 This new pocket digital unit is the most useful food preparation tool we have found to date. It is completely waterproof, accurate and tough, has user-calibration, and can be used for dishwasher temperature monitoring.

AQA 1264 Economy Digital Thermometer

$11.50 SALE All QA offers this hand probe unit as an alternative to the familiar bimetal coil thermometer used for food preparation. The upward facing dial allows a convenient viewing angle. Light and easy to use.

AQA 1282 Digital Reefer/Freezer Thermometer

            $42.95
This digital mounts on the wall or stands on the counter and displays max-min data and also sounds an alarm when a preset temperature is reached. This unit also is available with a glycerol bottle sensor to simulate true food temperatures (AQA 1281)

AQA 1397 Digital Time-At-Temperature Thermometer

             $30.50

This countertop unit allows cooking by time, temperature reached, or both. When cooking is complete according to the setting, the alarm sounds. Magnetic base keeps the unit secure. Can also be wall-mounted. Once you use this unit, you will not want to be without one.

AQA 1283 Big Digit Refrigerator Thermometer

             $39.95 Easily seen 1 1/8''H display digits. Probe in Freezer or Refrigerator. Constantly displays temperature of exterior air plus interior. Cable is small to run between door gaskets. Min/max probe for ice bath chill-down or water bath thaw.

AQA 1411 Water Resistant Digital

          $32.50

This display digital thermometer can be used near washing areas, over steam kettles and with ice or water baths. Mount on the wall or stand on counter. Magnet, suction cup, Velcro^� all provided.

Remote Sensing Digital Thermometers

See our IR Thermometer Information Page | IR Thermometer Listing with Ordering Information

Infra-red digital thermometers sense temperature from a distance. The radiation of infra-red ("IR") light from surfaces is related to the temperature of the object--you cannot see this heat radiating light, but the IR thermometer can see it. The IR thermometer "sees" the intensity of this light and converts it into an equivalent surface temperature.

Remote sensing is needed when speed, numerous reading, and necessary distance from the measured object are requirements. If you can't reach it to make a surface reading, or if you need to scan hundreds of areas in a short period of time, then an IR digital thermometer is what you need.

The key to IR thermometry is to make comparisons between what you get with the IR "gun" and what you get with a direct touch reading at the surface or a penetration reading within the object. IR readings can be misleading, since they can also "see" air temperatures and also they only look at the thin outer skin temperature of a target object. With care, however, the advantages of using a gun are tremendous--you can make dozens of measurements in a minute or two--the only limitation is getting to one measurement location to another.

All QA offers the best selection of IR digital thermometers available anywhere--from simple and very inexpensive devices to the best of laser sighted and regular IR guns.
