2½” Low Pressure Diaphragm Vacuum Gauge

The low-pressure diaphragm gauge offers the pinnacle in both performance and accuracy for pressure and vacuum applications up to and including 10 psi. Such uses in the vacuum regulators. The D2577 is constructed from a single beryllium-copper diaphragm affixed to a precision machined brass plate. This advanced design, coupled with a high-precision, milled-teeth brass movement, provides the user with a low-pressure instrument that is without equal.
