The Rotronic CP11 has a measuring range from 0 to 5000 ppm, 0.1 to 99.95 %RH, and -20 to 60 °C
The CP11 is the most recent improvement of an economical multiple parameter meter that all the while measures and records CO2, humidity and temperature. The CP11 is also capable of calculating the dew point and wet bulb temperature. Equipped with the field-tested ROTRONIC HYGROMER® IN-1 humidity sensor, this instrument offers top notch esteem for cash. The CP11 includes the ROTRONIC SW2.1 software which can be utilized to program, download data and save logged files.
