Gas Miser™ Demand Regulator:
no need to manually open or close a valve for accurate calibration once attached to the calibration cylinder. The Gas Miser Regulator is designed for use with pumped instruments and supplies the exact gas flow for the instrument pump. No ON/OFF valve is necessary because the regulator automatically turns itself off when not in use, simplifying the test and calibration process and saving calibration gas -
