Dwyer 476A Single Low Pressure Manometer

The Dwyer 476A Single Low Pressure Manometer is a handheld instrument designed for low-pressure measurement in HVAC and combustion applications. It offers ±1.5% full-scale accuracy, electronic zeroing, selectable pressure units, and automatic power-off for efficient field operation.

The Dwyer 476A Single Low Pressure Manometer is a handheld instrument for measuring low pressure in HVAC and industrial systems. It uses electronic zeroing and delivers ±1.5% full-scale accuracy.

The Low pressure differential manometer measures pressures from -20 to 20 in. w.c. Technicians use it to check field instruments and adjust fuel mixtures in combustion systems. The rugged extruded aluminium case protects the instrument during demanding field work.

A one-button auto-zero function allows quick calibration before measurement. The automatic power-off feature helps extend battery life. Users can also select from nine English or metric pressure units for fast setup.
