The DPC-300A Dual System Pressure Calibrator isn’t just a replacement for the old “box” calibrator. With full digital precision and accuracy, a dual pressure system and a built-in loop calibrator function, it’s a pressure calibration powerhouse in a portable format. A dual pressure system means you can use regulated plant air or internally generated pressure sources for calibration. The internal pump goes up to 300 psi with pushbutton ease. Exact values are set using the fine vernier control knob. Plant air, up to 100 psi is controlled with a precision regulator for low inches of water on up.
