Ashcroft Series 1490, Low Pressure Diaphragm Gauge


The Ashcroft® Type 1490 low pressure diaphragm gauge is designed to measure pressure from 10 in.H2O to 15 psi, both positive and negative pressures. This gauge uses a very sensitive diaphragm capsule to measure low pressure and vacuum. The gauge is specifically designed for use whenever the pressure medium is a gas that is not corrosive to beryllium copper, brass, polysulfone and RTV silicone.

The polysufone case is suitable for intermittent or continuous service on natural gas provided a .013½ throttle plug is installed in the socket. Typical applications are, but not limited to, vacuum pumps, gas leak detectors, air compressors, air fi lters, gas burners, gas measurement, vacuum ovens, suction regulators and respirators.
