DAFM4, Digital Airflow with Humidity Tester

The DAFM4 is the tool for all your airflow measurement needs. With the DAFM4 you can directly capture air temperature, relative humidity, and air velocity. It also calculates wet-bulb temperature, dew point temperature, and air volume. Enter duct dimensions for live or timed average of air-flow in CFM (or CMM), or use the effective area of a grill for outlet volume measurements. Air volume is displayed in real-time, or choose a timed average with start/stop capabilities to traverse ductwork. Features: 0.7” diameter vane head with 39" long telescopic & scale marked probe Mini vane probe with built-in temperature & RH sensor Up to 1 hour accumulative average Metric & imperial scales Handheld size, easy to carry In-duct or grill surface measurements Low battery indication Fast, accurate response Display Max/Min value Hold function freezes current readings Sleep and non-sleep selectable Powered by 9V batteries or 9V DC adaptor Functions: Measures: Air velocity, temperature, RH% Calculates: Air volume, web bulb, dew point Includes: 0.7” small diameter air vane on 39" long telescoping probe Hard carrying case 9V battery Manual
