The Amprobe dual-input thermometer is designed to measure two temperatures simultaneously in a variety HVAC, electrical, industrial, and automotive maintenance applications. The thermocouples support superheat and subcool applications, and cut-out and cut-in temperature measurements. The meter has an offset mode that can be used to compensate for thermocouple error. The meter has a back-lit LCD screen with data hold to save readings for later viewing, and displays minimum and maximum temperature with elapsed time, and average and relative temperature calculations. The device operates on one 9V battery (included), which provides approximately 200 hours of use. The auto-power-off feature turns the meter off after approximately 15 minutes, and can be disabled. A low battery indicator helps prevent false readings.
