4″ Low Pressure Gauge

The 4″ low pressure  gauge offers the pinnacle in both performance and accuracy for pressure and vacuum applications up to and including 10 psi. Such uses include gas-draft indication, air flow & filtration, leak detection, etc.
The LP40 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.
