CMM Dial Pressure Gauge
The Heise® model CMM precision pressure gauge yields consistent, reliable accuracy through the use of precision machining and refined Bourdon tube technology. Pointer rotation of up to 660 degrees with up to 1600 divisions offers high resolution to easily support tight tolerances. As a mechanical instrument, the gauge does not require a power supply. 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 continues to be the #1 choice in ASME B40.100, grade 4A precision mechanical pressure instrumentation.
Key Features:
- Accuracy ±0.1% of span
- Gauge, Compound and Vacuum ranges
- Pressure ranges 30 to 10,000 psi
- 660 degree of pointer rotation
- Includes small “scale indicator” pointer
- Mirror-band dial and knife-edge pointer eliminates paralax error while
assuring easy readability of precise measurements - Solid-front case design and blow-out safety back protect users from
extreme overpressure - Optional Thermal Compensation – to maintain accuracy over a wide
temperature range from -25° to +125°F
