- Used where operator safety is a must
- Ideally suited for process, chemical and petroleum industry applications where chemical compatibility and contamination is a concern
- Processes where pulsation or vibration exist
- StabiliZR™ dampened movement minimizes effects of pulsation and vibration without liquid filling
- Solid phenolic front and polypropylene pressure relief back safety case
- ±0.5% accuracy
- Stainless steel full rotary movement
- Micrometer adjustable pointer for ease in calibration
- Under and overload stops
- 316L stainless steel or brass wetted parts standard
- Restrictor screws standard on dual scale (optional on single scale gauges)
- ASME B40.100 compliant
- RoHS compliant (SS and Monel® internals only)
- CRN registered
- 5 year warranty
