The portable Low Pressure Calibrator (LPC) is a high-accuracy, self-contained cali-bration system, says the company. Designed for lab-oratory and industrial applications, the instrument measures gauge and differ-ential pressures with an accur-acy of better than 0.035%, generates low reference pressures, and programs the calibration of pressure sensors and other devices, the company says. Features include an intelligent auto-zero function that helps to eliminate errors in measurement.
