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 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.

Remote Sensing Digital Thermometers

See our IR Thermometer Information Center | Product Listing with Prices and 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.
