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.

The pressure gauge is helium leak tested and the internals
are electropolished to optimally meet purity standards.
The instrument complies with SEMATECH and SEMI
standards to optimally ensure the quality your applications

With such UHP characteristics, the instrument is suitable
for the semiconductor and flat panel industries, various gas
distribution systems, as well as medical gas applications.
