The EiUK PC4is an appliance for verification and calibration of pressure sensors, pressure gauges, as well as pressure switches for low pressures. The combination pressure measuring unit and pressure generator allows a variety of applications in the laboratory as well as in the field.
The EiUK PC4 can be used with battery (9V E-block) or from the mains (plug-in power supply). The robust inductive measuring cell covers a wide pressure measuring range by means of a 1 : 5 pressure range selector.
The EiUK PC4 can be delivered for 3 standard measuring ranges. Response time of the measuring signal can be selected for 3 steps. The pressure is displayed on a high contrast LC display with 12.5 mm characters. An analogue output is available on request. For greater volumes an integrated hand pump is used to generate pressure and metal belows is used for precise adjustment. Two integrated valves are used to vent the measuring equipment.
