Digital CFM Airflow Meter – CFM Master II

Simultaneously displays air flow and temperature readings for convenient HVAC and cleanroom filter monitoring

One-piece design allows easy single-hand use in hard-to-reach locations

Displays air velocity in FPM, MPH, KPH, Knots, MPS, and CFM

Switches °F and °C scales

Data Hold function is perfect for measuring transient or difficult-to-view conditions

Includes MIN/MAX and multi-point averages

Precision fan bearings ensure long, no-maintenance service life

RS232 output permits computer storage and analysis
of data (order RS232 kit No. 5401-31A separately)

This portable, once-piece digital air flow meter is the ideal service tool for HVAC and airflow technicians. It also allows easy monitoring of vertical laminar air flow inside a cleanroom.

Versatile Scale Options and Control Features

The CFM Master II provides simultaneous display of air velocity and temperature in an easy-to-read LCD screen. It provides minimum and maximum values and measurement of up to eight multi-point readings. The data hold function is ideal for transient readings, and the auto power off function conserves battery life.

Air velocity readings are displayed in any of the common scales in use: FPM, MPH, KPM, Knots, MPS and CFM. Temperature scale switches between °F and °C.

This unit includes one 9-volt battery, a hard case and an RS232 serial output.
