212C Low-Pressure Pneumatic Test Pump – -0.5 to 0.5 bar

212C Low-Pressure Pneumatic Test Pump

The 212C is a compact pneumatic source for generating pressures from -0.5–0.5 bar. It is designed for differential and low-pressure gauges, transmitters and sensors that require careful control close to atmospheric pressure.

The fine-adjustment screw provides increments of 0.01 Pa for making very small pressure changes around each test point. This is the fineness of the pressure adjustment, not the accuracy or uncertainty of the calibration system.

At 240 × 130 × 130 mm and 1.5 kg, the 212C is the smallest pump in this group and is convenient for field or bench use. A separate reference instrument, suitable connections and a controlled procedure are required for traceable comparison work.
