Product Description

The Ashcroft 1490 low pressure diaphragm gauge is designed to measure pressures from 10" H2O to 15 psig, both positive and negative, using a very sensitive diaphragm capsule. The gauge is specifically designed for use on non-corrosive gases. The polysufone case is suitable for intermittent or continuous service on natural gas provided a .013" throttle plug is installed in the socket. Typical applications include vacuum pumps, gas leak detectors, air compressors, air filters, gas burners, vacuum ovens, suction regulators and respirators.
  • Diaphragm capsule design for low pressures
