Ordering Numbers
The standard scale contains two sets of calibrations (dual scale) in the pressure units inches of water and psi. Dial
markings in the negative range are in red colour and in the positive range in black colour.

Overpressure protection
A pressure relief valve protects the mechanism
(capsule); pressure up to 90 psi will not damage the
mechanism nor affect accuracy. A built-in relief valve
and a flow restrictor protect the case from pressures
up to 10 times the case rating of 35 psig. This valve
is an emergency-protective device only.
