Heise® Model CM Dial Pressure Gauge


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 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 pressure instrumentation.

Standard Features
  • Pressure measurement accuracy of ±0.1% F.S., ASME B40.1 Grade 4A (See datasheet HE-2 for complete product specification)
  • Pressure ranges from 0/15 psi to 0/100,000 psi
  • Available in 6", 8.5", 12" and 16" dial face diameters
  • Gauge, absolute, vacuum and compound ranges
  • 300° pointer arc for most ranges
  • Bourdon tubes available in Beryllium Copper and 403 Stainless Steel (range dependent)
  • Solid-front protective case with "blow-out" rear cover
  • High and low pressure-limit stops
  • Bleeder tip to allow flushing of Bourdon tube
  • Mirror band dial and knife edge pointer to eliminate parallax reading error
  • NIST traceable certification of calibration
Optional Features
  • Temperature compensation; eliminates temperature errors from -25°F to 125°F
  • Peak load indicator
  • Slotted link to protect gauge from sudden pressure release
  • Wall-mounting brackets
  • Dual scale or custom scale dials
