Dwyer Fluid Filled and Handheld Digital Manometers
Dwyer Instruments manufactures a wide variety of digital and fluid filled manometers. Digital manometers range in accuracy from 1.5% (low cost) to 0.05% (high-end) full-scale accuracy. These manometers measure single pressure, differential pressure, absolute pressure, or gage pressure. The series 475-FM Mark III and the series 477-FM digital manometers are FM approved intrinsically safe for hazardous applications. Optional carrying cases are sold separately.
Fluid filled manometers provide an even less expensive approach to measuring positive, negative, and differential pressures. Series Mark II inclined/vertical plastic manometers can not only measure a wide range of pressures, but can measure air velocity as well. Tube manometers are highly durable and provide portable, direct readings.
Applications:
- HVAC systems
- Clean room checks
- Field calibration
- Laboratories
- Servicing gas appliances
