bimetallic thermometer accuracy

The industry standard for bimetal thermometer accuracy is +/-1% of the full scale (Grade A per ASME B40.3). Temperature readings normally 

7/16 · Periodically, all thermometers must be calibrated or adjusted to accurately measure temperature. Here’s how to do it: Check the accuracy of thermocouples and digital

How do you calibrate a bimetallic stemmed thermometer Fill a large container with ice Add clean tap water until the container is full. Stir the mixture well. Put the thermometer stem or probe into the ice water Make sure the sensing area is underwater and not touching the sides of the container. Wait 30 seconds or until the reading stays steady.

Bimetallic stemmed thermometers are calibrated using the ice-point method. Calibrate on a regular basis and after using the thermometer with very hot or very cold foods, or after dropping or jarring it. In a clean styrofoam cup, make an ice water slush by filling the cup halfway with ice cubes and the rest with water.

Produces typical accuracy better than ASME B40.3 Grade AA (1%- 1⁄ 2 %-1%) full span ★ OVER TEMPERATURE LIMITS • Up to 250°F 100% • 250° F to 550°F 50% • 550° F to 1000°F 800°F for continuous use, intermittent use over 800°F ★ TEMPERATURE RANGES • 20 Standard Fahrenheit ranges from -100° to 1000° • 20 Standard Celsius ranges from -75° to 550°

1, normally closed thermostat set the temperature point is "off temperature"If the product accuracy is ± 5 ℃,For example: we buy the product is 120 ℃,Then his disconnect temperature between 115 ℃ ~ 125 degrees, are qualified products.Reset the temperature of the relative accuracy will be much lower,General factory set reset temperature

Bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. Bimetallic thermometer is a round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end

Bimetallic thermometer * ; cheap. requires frequent calibration to maintain accuracy ; durable. fairly slow response ; can be used for thermograph. easily
