Description

The model 230.15 is a bourdon tube pressure gauge with up to 2 Reed contacts model 851. It was created for high purity applications that require discrete monitoring outputs for globally installed systems and life safety applications.

The switch point can easily be adjusted by removing the window and putting the mark pointer on the desired value on the dial's circumference.
