This Extech product datasheet presents the IR Thermometer with Color Alert, a 12" distance dual laser infrared thermometer with a blue backlit dual LCD display that changes to red when a reading exceeds the programmed high or low set point. The datasheet lists the sensor's features, such as the 150 millisecond response and the two lasers that converge at 12" to mark where accuracy is highest.
A specifications table gives the measurement range, repeatability, basic accuracy, adjustable emissivity, field of view, dimensions and weight. The ordering information covers model 42509 and a 42509-NIST version with calibration traceable to NIST; the unit is supplied complete with case and 9V battery.
