| Infrared Thermometer |
 |
|
An infrared thermometer is a non-contact temperature measurement device. Infrared Thermometers detect the infrared energy emitted by all materials -- at temperatures above absolute zero, (0°Kelvin)-- and converts the energy factor into a temperature reading.
The most basic design consists of a lens to focus the infrared (IR) energy on to a detector, which converts the energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation. This configuration facilitates temperature measurement from a distance without contact with the object to be measured. As such, the infrared thermometer is useful for measuring temperature under circumstances where thermocouples or other probe type sensors cannot be used or do not produce accurate data for a variety of reasons. Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an EM field, as in induction heating; where the object is contained in a vacuum or other controlled atmosphere; or in applications where a fast response is required. |

| 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.

| Dial Thermometer |
 |
|
A dial thermometer, also known as a differential absorption lidar thermometer, is a mechanical device that uses a metal pointer on a circular scale to indicate temperature measurements. The device has two primary components; the metal pointer, or needle, and a temperature sensor. These sensors may be bi-metal or bimetallic, liquid or gas filled, or vapor-tension-based.

| Temperature Gauge |
 |
|
A device used to indicate the temperature of an item being monitored. The display can be an analogue dial, an analogue range or a digital readout. Common methods of measuring temperature include bimetallic strip (the bending of which increases with temperature) and the thermocouple which produces an electronic voltage that depends on the temperature.
