Using one of three varieties of temperature sensors (thermocouple, NTC thermistor and resistance temperature detectors [RTD or PT100]), Ross Brown Sales’ ETI Industrial Thermometers are available in a number of unique models.
NTC Thermistors: NTC thermistor probes are also based on a temperature dependent resistance change in the sensor element. But unlike resistance thermometer detectors, thermistors have a negative temperature coefficient, ie, the resistance decreases with increasing temperature.
Resistance temperature detectors: Resistance temperature detector (PT100 or RTD) probes consist of a flat film or wire wound platinum resistance sensor element. The measurement resistance value changes in the line with the temperature being measured.
Thermocouples: Thermocouple probes consist of two wires of dissimilar metals or metal alloys welded together. Thermocouples are based on the thermoelectric effect. There are various types of thermocouple, types K and T being the most common.
The Therma Series Industrial Thermometers allow interchangeable type K thermocouple probes. With the large, easy to read LCD display and long battery life, these heavy duty thermometers are reliable units for various applications.
The Precision PT100 Thermometer is a high accuracy unit with interchangeable PT100 probes.
There are various Bi-Metal Dial Thermometers that are ideal for industrial applications including waterproof, heavy duty and pipe surface thermometers.
