More About this Item

This heavy-duty manometer measures suction line or liquid line pressure and temperature to calculate and display superheat and sub-cooling for air conditioning (A/C) units. Dual pressure connections, dual temperature connections, and triple-line display—lets you read P1-P2, T1-T2, and ambient temperature measurements simultaneously.

Multifunction differential pressure and temperature meter features Min/Max/Average functions, data hold, and auto power-off. The dual Type K thermocouple inputs come with electronic offset to compensate for differences between thermocouple probes—increasing temperature accuracy.
