CUSTOM FEATURES AND PROGRAMMING
Because these gauges are microprocessor controlled, it is possible to provide custom
control features at surprisingly reasonable prices. The software is "burned" into the
microprocessors, which are socketed and easily replaced by a user. Contact the Digivac
Company to discuss your needs.
If the gauge is to be used in a neon sign processing facility, it must be installed with a
stopcock or a solenoid valve to protect it from exposure to the system and possible damage
during high voltage bombarding. Battery operated gauges are also offered and are
particularly suited to neon applications.
SPECIAL REQUIREMENTS
It is the policy of the Digivac Company to customize instruments for specialized
requirements whenever it is economically feasible to do so. We encourage inquiries about
your special needs.
