The 309 surface temperature thermometers are unilateral thermal sensors, which measure the temperature of the contact surface. These instruments are fully enclosed to protect the bimetal from dirt and dust. Accuracy of the thermometer is ±2% of full scale range. 2 inches in diameter and weigh only 1 ounce. The bimetallic sensor is designed to permanently retain its calibration.
-50° to 110°C Fully Enclosed to protect Bimetal. These thermometers can be used for external wall leakage temperatures of refrigerators, cold chambers, freezers, ovens, boilers, electric motors, cylinder blocks, plastic dies, and rubber molds. All types of ducts, wall, ceiling, and floor, temperatures of building or storage areas.
