Details for 477AV-4

477AV-4 Digital Manometer by Dwyer Instruments Dwyer Instruments' 477AV-4 Digital Manometer is a robust tool designed for precise pressure measurement in industrial and maintenance applications. Its compact size and lightweight design allow for easy portability, while the large, easy-to-read display provides clear readings even in low-light conditions. This manometer measures pressure in a wide range of units, including psi, inches of water column, and millibars. The maximum pressure capacity of 30 psi makes it suitable for various applications, such as testing pressure regulators, verifying vacuum levels, and measuring gas pressures. The 477AV-4 features a rugged construction with a chemical-resistant polycarbonate case and a stainless steel sensor. This ensures durability and reliability even in harsh environments. The built-in backlight and zeroing function enhance usability and accuracy. Key Features: * Range: 0 to 30 psi * Accuracy: Â±0.5% of full scale * Units: psi, inches of water column, millibars * Compact and portable design * Large, easy-to-read display * Backlight for low-light conditions * Zeroing function for accurate measurements * Chemical-resistant polycarbonate case * Stainless steel sensor Applications: * Testing pressure regulators * Verifying vacuum levels * Measuring gas pressures * HVAC system diagnostics * Industrial maintenance and troubleshooting Our HVAC supply store offers the 477AV-4 Digital Manometer at competitive prices with fast shipping.

Series 477AV Handheld Digital Manometer

Measures Pressure, Flow and Velocity; ±0.5% Accuracy

The Series 477AV Handheld Digital Manometer 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.

NIST CALIBRATION available in Product Configurator.
