Product Overview
The Dwyer VP1 is a genuine 100 mm vane thermo-anemometer replacement probe designed for the Dwyer 473B-1. It provides a replacement solution when the original probe is damaged, worn or otherwise needs to be replaced, allowing the existing 473B-1 meter to continue being used for HVAC airflow measurements.
The wired 100 mm vane measures air velocity from 40 to 5000 ft/min (0.2-25 m/s) with ±1.5% of reading accuracy. The probe can register air speeds as low as 0.25 m/s (50 fpm), making it suitable for low-flow measurements at applications such as filter faces and large return grilles.
The VP1 supports the 473B-1's measurement functions for air velocity, volumetric flow, temperature and humidity. Its listed air temperature range is -20 to 212°F, with temperature accuracy of ±0.54°F at 77°F. Humidity measurement covers 0-100% RH.
A flexible coiled cable provides reach for duct and grille measurements while keeping the connection organized. The probe has an 8-inch depth for duct insertion and weighs approximately 0.95 lb.
The VP1 is CE and RoHS approved. Using the genuine replacement probe specified for the 473B-1 helps maintain compatibility with the existing instrument and its intended measurement functions.
