Rotronic CP11 CO2 is a carbon dioxide measurement instrument – the economical multiple parameter meter for measuring and recording levels of CO2 gas also calculates dew point and wet bulb temperature.
Rotronic CP11 CO2 is a carbon dioxide measurement instrument – the economical multiple parameter meter for measuring and recording levels of CO2 gas also calculates dew point and wet bulb temperature.
The Rotronic CP11 instrument is equipped with the field-tested Rotronic Hygromer IN-1 humidity sensor offering unbeatable value for money.
Typical applications of the Rotronic CP11 include air quality monitoring in underground car parks for safety and leak monitoring in filling plants.
Key Features – The Rotronic CP11 is capable of calculating dew point and wet bulb temperature and features automatic or manual logging. There is also easy field calibration by simple connection to a known reference.
Connections – The CP11 features a mini USB port for connection to a PC and a 5 VDC power supply, for connection of the optionally available AC adapter.
Large Display And Controls – With a back-light for improved reading. There are also large buttons for easy operation of the measuring instrument.
Sensors/Calibration – The Rotronic CP11 features the Hygromer IN-1 humidity sensor. Calibration is possible at 35/80 %RH and calibration of CO2 possible at 0 and 400 ppm.
Rotronic CP11 handheld instrument evaluates the quality of air along with a measurement of the levels of carbon dioxide (CO2) gas present. In closed areas with inferior ventilation and populated with people, carbon dioxide levels can quickly develop in high concentrations.
CO2 gas is colourless and odourless making it impossible for humans to detect alone. In addition the gas occurs naturally in the earth’s atmosphere and a high CO2 content becomes apparent in humans through rapid fatigue and loss of concentration.
In order to initiate suitable counter measures such as an increase in the supply of fresh air, it is important to data log and record not only parameters such as relative humidity and temperature measurement, but also the CO2 gas content.
Rotronic devices including transmitters, data loggers and hand held instruments are used for regulating ventilation in living areas, offices, classrooms, cinemas, hospitals and also for measuring CO2 pollution in garages, tunnels and logistics facilities. Rotronic carbon dioxide gas measurement instruments monitor indoor air quality (IAQ) safeguarding the health, productivity and comfort of occupants.
