Supco EM90 Infrared and Thermocouple Thermometer with Probe, -50 to 300 Degrees C, -58 to 572 Degrees F, Accuracy of + or - 1.5% of Reading Plus 2 Degrees C

The Supco EM90 infrared thermometer with K-type thermocouple wire probe is for measuring temperature in heating, ventilation, and air-conditioning applications, including refrigeration and heating systems, supply and return registers, circuit breaker panels, motors and bearings, transformers, and ducts. The infrared sensor measures temperature from -50 to 300 degrees C (-58 to 572 degrees F), with a best accuracy of + or - 1.5% of reading plus 2 degrees C (4 degrees F). The infrared sensor measures temperature from a distance for applications involving hard-to-reach, moving, hot, or electrified equipment. The detachable K-type thermocouple wire probe takes contact surface temperature measurements and provides a broader temperature measurement range but lower accuracy than a thermistor sensor. The infrared sensor has a 2:1 distance-to-spot ratio, which means the measurement field measures approximately 2 feet in diameter when the target is 1 foot away. A built-in laser pointer helps improve aiming accuracy when taking infrared measurements. The LCD screen can display the current temperature, the highest or lowest temperature reading for the session, and the average temperature for the session. The operator can choose to display readings in degrees Fahrenheit or Celsius. The hold function keeps a measurement on the display so it can be recorded. The display is backlit for readability in low light. The thermometer operates on two AAA batteries (included), and it can be set to automatically shut off after 25 seconds or 20 minutes of non-use to conserve battery life. A lanyard is included to help protect against accidental drops, and a sensor cover helps protect the inputs from debris.

*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Digital infrared thermometers measure the temperature of surfaces from a distance. They may measure temperature in Celsius, Fahrenheit, or both. Infrared (IR) thermometers work by focusing the infrared radiation emitted by a surface onto a detector called a thermopile. The thermopile turns the heat into electricity, which is measured and converted to a temperature reading. The reading is then displayed on an LCD display. IR thermometers are used to measure temperature when an object is fragile, as in ear thermometers, or dangerous to be near, as in the case of industrial equipment.

Supco manufactures test instruments and replacement parts for heating, ventilation, air conditioning, and refrigeration systems. The company, founded in 1945, is headquartered in Allenwood, NJ.
