  • PCE Instruments HVAC 4 Differential Pressure Gauge for Refrigeration Systems

    # 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.
    • The PCE-HVAC 4 differential pressure gauge is often used in the installation and maintenance of refrigeration systems. In particular, the high measuring range up to 34.47 bar is a big advantage of the differential pressure gauge, as most differential pressure gauges do not reach these measuring ranges.
    • 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.
    • The PCE-HVAC 4 differential pressure gauge is often used in the installation and maintenance of refrigeration systems. In particular, the high measuring range up to 34.47 bar is a big advantage of the differential pressure gauge, as most differential pressure gauges do not reach these measuring ranges. The handy design, in combination with the battery mode, enables non-stationary measuring operation.
    • The measurements of the differential pressure gauge are made via the corresponding measuring lines. On the sides, shown in yellow, the temperature measurement by thermocouples is made. The corresponding setting also determines the temperature difference. The internally installed NTC sensor is responsible for the ambient temperature. The pressure hoses are attached to the upper side. The pressure is determined there as well as the differential pressure.
