Model: ST-8835
The Reed ST-8835 infrared thermometer with K-type thermocouple input and probe is for measuring temperature in industrial applications such as heating, ventilation, and air conditioning installations. The infrared sensor measures temperature from -50 to 1050 degrees C (-58 to 1922 degrees F) with a best accuracy of + or - 1.5% of the reading plus 2 degrees C (3.6 degrees F). The infrared sensor takes measurements from a distance for applications involving hard-to-reach, moving, hot, or electrified equipment. The K-type thermocouple 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 30:1 distance-to-spot ratio, which means the measurement field measures approximately 30 feet in diameter when the target is 1 foot away. It has an adjustable emissivity setting to help improve measurement accuracy on a range of surface types, and the thermometer automatically selects the appropriate emissivity setting for a target. 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, the average temperature for the session, and the difference between two temperatures. 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, and the thermometer's internal memory can store up to 20 sets of data. The display is backlit for readability in low light. When a reading exceeds the user pre-set high or low measurement limits, an alarm will sound. The display shows polarity and indicates when the measurement is outside the acceptable operating ranges. A trigger lock on the handle provides continual measurements. The thermometer operates on one 9V battery (included), and it automatically turns off after a period of non-use to conserve battery life. A carrying case is provided for tr...
