Ashcroft 1490 Low Pressure Gauge

Ashcroft^® 1490 low pressure gauges are designed to measure from 10in. H₂O to 15psi, both positive and negative pressures. These gauges use a very sensitive diaphragm capsule to measure low pressure and vacuum. They are designed for use whenever the pressure medium is a gas not corrosive to beryllium copper, brass, polysulfone and RTV silicone. Typical applications are vacuum pumps, gas leak detectors, air compressors and filters, gas burners, gas measurement, vacuum ovens, suction regulators, and respirators.
