The Dwyer 477AV-1 Handheld Digital Manometer sold by Ace Instruments
is now available with pressure, flow, and velocity measurements along with a number of other convenient features. The built-in air velocity and flow calculations provide accuracy and conserve time and error associated with manual calculations. Also featured on this unit are adjustable zero and span values for calibrating in the field, as well as a damping feature to compensate for the fluctuating of readings.
The accuracy that the 477AV-1 provides is critical to maintenance personnel and technicians who require a highly accurate standard to check their instrumentation or equipment, to ensure proper performance. The digital display offers a backlight feature for easier viewing in darker areas. Meanwhile, battery conservation is monitored and displayed in the event of low battery voltage. The digital manometer will automatically shut off after 20 minutes to prevent battery drain. This shut-off time can be reduced or disabled if desired. Series 477AV can be field-calibrated by setting zero and span values. Furthermore, the damping feature compensates for the fluctuating readings by averaging input values to display a more stable readout. Included is an audible and visual alarm to warn over flow, over pressure or over velocity.
The Series 477AV features a menu structure outline printed on the back of the aluminum casing. Comprehensive written instructions, a wrist strap, and a 9 Volt alkaline battery are also included.
