Ashcroft 1490 Low Pressure Diaphragm Gauge

Ashcroft 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 polysulfone case is suitable for intermittent or continuous
service on natural gas provided a .013 throttle plug is installed in the socket.
Typical applications are, but not limited to, vacuum pumps, gas leak detectors, air
compressors, air filters, gas burners, gas measurement, vacuum ovens, suction
regulators and respirators.
