Kestrel 4200 pocket air flow tracker

November 2011 Flow Measurement & Control

The Kestrel 4200 pocket air flow tracker allows instant and accurate readings of air flow and environmental conditions based on the instantaneous air velocity and cross-sectional area through which the air is passing. Ideal for HVAC, health and safety, facilities and maintenance engineers, the Kestrel 4200 offers a multitude of features to help monitor the environment in one single handheld instrument.

The Kestrel 4200 combines all the features of the Kestrel 4000 and Kestrel 4100 and also makes the HVAC technicians job even easier via built-in wet bulb temperature and humidity ratio measurements, as well as barometric pressure and altitude. Like the 4100, the 4200 features automatic volume air flow readings. Simply enter the duct shape and dimensions, hold the unit in the air stream and the volume air flow readings are displayed. The convenient averaging mode ensures that the volume air flow readings are accurate in any airflow or duct size and shape.

Individual functions can be displayed in three different formats: current, min/max/ave and chart. There are also three user screens, which can be customised to display the three most appropriate functions for the application. The instrument can be set to log data automatically (as well as manually) at programmable intervals, in order to display a history of environmental information – graphs can display up to 1600 data points. When a data point is highlighted, the value, time and date of capture point can be shown on the easy to read display with illumination for use in poor lighting conditions.

High precision jewel bearings and a lightweight impeller provide accurate air flow measurements and the ability to operate at speeds as low as 0,4 m a second. The impeller is user-replaceable in case of damage to ensure high accuracy levels for life. An integral cover protects the impeller when not in use.

A precision external thermistor sensor provides fast response temperature readings and accuracy of 1°C. The 0,1° resolution of the display aids in determining when a consistent reading has been reached. A special housing protects the relative humidity sensor from contamination and on-screen customisation allows the technician to personalise the 4200. The unit is powered by two AAA batteries and has two power saving modes to prolong battery life.
