Wohler FA 430 Fan anemometer (incl CO2)

Wohler FA 430 Fan anemometer
Used to measure the air speed, temperature, and humidity, as well as CO2 levels.
Can be connected to a cone or funnel to measure the volume flow of air vents.

Flow velocity: 0.5-30 m/s
Volume flow: 0-99,999 m3/h
Temperature: -20 to 60 Celsius
CO2:: 0-9,999ppm

Flow velocity: 0.1 m/s
Volume flow: 0.1 (0-9,999) or 1 (10,000-99,999)
Temperature: 0.1C/F
CO2: 1ppm

Flow velocity: ±(1.5% of reading + 0.3m/s) for under 20m/s, ±(3% of reading + 0.3m/s) for above 20m/s
Temperature: ±0.6C
CO2: ±30ppm ±5% of reading (0-5000ppm)
CO2 warm-up time: 30 seconds
