Temperature Gage

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

Things to Consider When Purchasing This Product:

ANALOG (BIMETAL THERMOMETER): Case (typically hermitically sealed stainless steel with 1" to 5" diameter); Window and ring (double strength glass or plastic); Accuracy in terms of percentage, plus or minus, of full scale, standard sizes should meet ASME B40.3 Grade A, pocket sizes should meet ASME B40.3 Grade 3; Measurement Range choices: dual scale degrees F and C, single scale degrees F or C; External reset to allow calibration to any specific temperature in the measurement range; Stem (typically 0.250" or 0.125" O.D. stainless steel in lengths from 2.5" to 72"); Connection style (typically threaded 1/4 or 1/2 NPT or plain non-threaded); Environmental conditions (instrument is not suitable for sustained temperatures exceeding 200F (93C)); Vibrating applications require case to be silicone filled to protect instrument; Thermowells prevent instrument damage and facilitate removal from a process with media that are corrosive or under pressure; Shipping weight; Warranty DIGITAL (ELECTRONIC THERMOMETER): Input type, Number of inputs, C/F switchable, Resolution, Accuracy, Maximum temperature measurement, Display (typically 3-1/2 to 5 digits), Backlit LCD, Battery life, Battery type, Input connection type, Delta T1-T2 (temperature difference between two probe locations), Data hold, Min/Max capability, Data storage, Hi/Lo limits with beeper; Other features to look for: compact, Water resistant, degrees K, Switchable for 3 or 4 wire sensors, auto power off, waterproof, dustproof, data-logging, printer port, NIST calibration certificate, Rugged case;, Included accessories; Warranty
