Energy Audit IR Thermometer/Scanner with Star Burst Laser Targeting (IRTC50) from General Tools & Instruments (General®) allows the user to designate a set point and determine whether subsequent readings are within or outside selectable ranges from that set point. The Star Burst laser targeting system lets the user easily determine the area being measured. The device is ideal for conducting energy audits; it can perform a progressive scan over a pre-determined area and check for temperature differentials. It also has a wide variety of applications for HVACR technicians, building inspectors, electricians, plumbers, manufacturing technicians, homeowners and others.

With the gun-style Energy Audit IR Thermometer/Scanner, a set-point reference temperature is first acquired and stored. Then the user selects one of three reference ranges (+/-1°, 5° or 10°F; 0.5°, 3° or 5.5°C). As subsequent readings are taken, tri-color light and buzzer alarms indicate if those readings are within, above or below the selected range.

The precision point-and-shoot IR Thermometer/Scanner easily and safely scans and measures surface temperatures without requiring direct contact to inaccessible or dangerous objects. It has a rugged, ergonomic design and features a large backlit LCD display powered by a single 9-Volt battery (included). The instrument has a measurement range of -40° to +428°F (-40° to +220°C) with an accuracy of +/-4°F/C, or 2% of reading. The unit has a fast response time of 0.5 seconds and repeatability of +/-1.5°F (1°C). Its practical distance-to-spot ratio of 8:1 is suitable for commercial and consumer applications.
