Manometer PCE-HVAC 4
The manometer PCE-HVAC 4 is a versatile measuring instrument for the determination of differential pressure, differential temperature and ambient temperature. The measurements of the manometer PCE-HVAC 4 are via measuring terminals, thermocouples and an internally installed NTC sensor. All measurements can be performed simultaneously. By simply plugging in or screwing on, the measuring terminals, thermocouples and pressure hoses can be attached to the differential pressure gauge. The PCE-HVAC 4 differential pressure gauge is powered by a high-performance 7.4V polymer Li-ion battery, which is charged via the mains.
