Low Pressure Diaphragm Gauges

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 include a gas-draft indication, airflow & filtration, leak detection, etc. The D2507/D2507L 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.
