Dwyer Instruments 475-1-FM Manometer
The Dwyer Instruments 475-1-FM Manometer is a field-ready intrinsically safe digital manometer designed for the precise measurement of positive, negative, or differential pressures. Engineered for natural gas pressure testing and HVAC troubleshooting, this rugged tool features a range of 0 to 20.00" w.c. (4.982 kPa) with a 10 psig maximum pressure limit. The FM approved rating makes it essential for technicians working in hazardous Class I, Div. 2 environments where combustible gas pressure monitoring is required. Housed in a durable extruded aluminum case, the solid-state 475-1-FM utilizes a silicon piezoresistive sensor to ensure ±0.5% full-scale accuracy. Dual push pads allow for seamless toggling between English and metric units and simplified auto-zeroing. Whether you are performing static pressure measurement on a boiler or pairing it with a Pitot tube for air velocity readings, this handheld unit delivers the reliable performance veteran contractors expect without the complexity of mechanical gauges.
Key Benefits- Intrinsically Safe: FM approved for use in hazardous locations (Class I, Div. 2, Groups A, B, C, D) commonly found in industrial gas applications.
- High Precision: Delivers ±0.5% FS accuracy, providing reliable data for field calibration and system balancing.
- Rugged Construction: Durable aluminum housing protects internal electronics from physical impact and environmental stress in the field.
- Versatile Media Compatibility: Rated for use with clean air and compatible combustible gases like methane, propane, and natural gas.
- Operator Efficiency: Large 0.42" 4-digit LCD and simple two-button interface minimize setup time and reduce collection errors.
Is the 475-1-FM suitable for measuring air velocity?
Yes. While native to pressure measurement, this manometer can function as an air velocity gauge when used in conjunction with a Dwyer Pitot tube and an air velocity calculator.
What type of tubing is compatible with the process connections?
The unit features dual-sized barbed connections that accommodate either 1/8" or 3/16" ID vinyl or rubber tubing for flexible field setup.
How is the zero-point maintained during testing?
Technicians can perform an auto-zero by venting both pressure ports to the atmosphere and pressing the zero button, ensuring accuracy across different ambient temperatures.
