Digital Thermometers

Thermistors or Themistor Meters and Probes have exceptional accuracy over ambient and biological temperature ranges, especially when compared to the next RTDs and thermocouples. They operate through a decrease in resistance as the temperature increases.

Resistance Temperature Detectors (RTDs) or Platinum Resistance Thermometers (PRTs) offer excellent accuracy, stability, and repeatability over a wide temperature range but are sensitive to mechanical shock. These instruments measure temperature by measuring the change in electrical resistance across a metal wire.

Infrared Thermometers read infrared energy as emitted from an object, convert it into an electrical signal, and display it as a temperature reading. They provide a fast response time for surface temperatures and also read a wide range of temperatures.

Thermocouple Systems (Meters and Probes) use a sensor composed of two dissimilar metals for measuring temperature. This different pairing of multiple metals (such as iron or copper) makes them operable for many different applications and highly versatile. Thermocouples are durable and immune to shock and vibration.

Digital Indicator Thermometers are used for general purposes such as monitoring the temperature of freezers, water baths, and incubators. They are also a good option for displaying ambient temperatures for food service purposes. Their accuracy varies by model but they are easy to read and may be battery operated, wireless, solar powered and/or wall mounted.
