The Dwyer 477A-1 and 477A-2-NIST Handheld Digital Manometers are precision instruments designed for a wide range of pressure measurement applications. These manual handheld manometers feature a high-resolution, backlit LCD display that clearly shows pressure readings up to 2000 PSIG (137.9 bar) with an accuracy of 0.1% of full scale or 0.5 PSIG (0.035 bar), whichever is greater.
The 477A-1 model features a 1/4-inch NPT connection, while the 477A-2-NIST model comes with a 1/4-inch NPT connection and NIST-traceable calibration certification. Both models have a rugged, water-resistant design, making them ideal for use in industrial and field applications.
The manometers also include a range of advanced features, such as a pressure unit selector, a hold function that freezes the display, and an auto-shutdown feature that conserves battery life. The manometers are powered by two AAA alkaline batteries, which provide up to 500 hours of operation.
In addition, the 477A-2-NIST model comes with a NIST-traceable calibration certificate, which verifies that the manometer has been calibrated to meet the highest standards of accuracy. This makes the 477A-2-NIST an ideal choice for applications that require NIST-traceable calibration, such as quality control and regulatory compliance.
Overall, the Dwyer 477A-1 and 477A-2-NIST Handheld Digital Manometers are high-precision, durable, and versatile instruments that are perfect for a wide range of pressure measurement applications. Whether you're working in an industrial setting or conducting field tests, these manometers will provide you with accurate and reliable pressure readings.
