Kestrel 4200 Pocket Air Flow Tracker

Kestrel 4200 measures
volume air flow in cfm, ls, m³s, m³m, m³h
air velocity (current, average, and maximum)
heat stress index
windchill
relative humidity
dewpoint
temperature in °f or °c
humidity ratio
barometric pressure
wet bulb temperature
altitude
density altitude
tired of cumbersome equations to calculate cfm?
like the 4100, the kestrel 4200 has taken the calculations and guess-work out of air flow measurements with automatic air flow readings. The convenient averaging mode ensures accurate cfm readings in any airflow or duct size and shape. For immediate and accurate air flow readings, simply:
1.enter the duct shape and dimensions.
2.hold the 4200 in the air flow.
3.volume air flow readings are displayed. No calculator required!
innovative design and features
the kestrel 4200 makes hvac technicians jobs even easier with automatic wet bulb temperature and humidity ratio readings. Of particular interest to dehumidification professionals, the kestrel 4200 measures relative humidity, dewpoint, wet bulb temperature and heat stress index as well as the humidity ratio—and the patented dual chamber humidity sensor assures fast and accurate readings in any environment. This multi-functional precision instrument also measures: volume air flow, air velocity, barometric pressure, altitude, wind chill, heat stress index, temperature, relative humidity and dewpoint, either ambient or in any accessible airflow.
