The calibrator supports pneumatic pressure and vacuum generation for low and medium pressure applications up to 20 bar and is also available with a hydraulic option for pressure generation up to 100 bar, making it suitable for a wider range of calibration tasks. With an accuracy of ±0.025% of full scale, the APC-P Series ensures reliable and repeatable measurement performance.
The instrument includes comprehensive electrical measurement capabilities, allowing simultaneous mA and voltage measurement, along with a 24 V loop-powered supply for direct calibration of transmitters. A built-in pressure switch test facility enables technicians to accurately detect opening and closing set points through display hold functionality. The calibrator features a large backlit graphical display, feather-touch keypad with a dedicated ZERO key, and useful diagnostic functions such as high and low peak pressure capture and over-pressure alarm. Housed in a durable IP65 ABS casing and powered by a rechargeable Li-ion battery, the APC-P Series offers a reliable and portable solution for pressure calibration, transmitter testing, and instrumentation maintenance across industrial applications.
