Heise Dial Gauges

The Heise® precision pressure gauge yields consistent, reliable accuracy through the use of state-of-the-art precision machining and the world's most refined ("Hi-Tech") bourdon tube technology. This eliminates the need for a power source and precludes the associated problems such as susceptibility to electronic line noise, power outage or potential fire hazard. In addition, this mechanical instrument is simple to operate, easy to troubleshoot, and can be readily flushed or purged to remove foreign matter or trapped gas. That's why the Heise precision dial gauge is the #1 choice in precision mechanical instrumentation.
