Digital Manometers

The 476A series digital manometers can be used to measure low pressures from -20 to 20 "w.c. with ±1.5% FS accuracy. The 478A digital manometers can be used to measure positive, negative, or differential pressures. Both are constructed of an extruded aluminum case for exceptional durability.

Measures positive, negative, or differential pressure of air and natural gases in ranges from 1 "w.c. (0.249 kPa) to 150 psid (10.34 bar). The dual push pads on the front panel control the on/off, auto-zero, and pressure unit selection, allowing for simple operation with no set up needed.

The 477AV series offers pressure, flow, and velocity measurements. The built-in air velocity and flow calculations provide accuracy and conserve time and errors. Additionally, it features adjustable zero and span values for calibrating in the field, as well as damping to compensate for the fluctuating of readings.

Versatile, hand-held, battery operated manometers available in several basic ranges for positive or positive differential pressure measurement and can tolerate most liquid media compatible with 316LSS. A memory function allows storage of up to 40 readings for later recall and a backlight provides auxiliary lighting for hard-to-see locations.
