Available to purchase from Instrument Solutions is the Rotronic CP11 is a handheld instrument that simultaneously measures and records CO2, humidity and temperature. It also calculates the dew point and wet bulb temperature. Equipped with the field-tested ROTRONIC HYGROMER IN-1 humidity sensor, this instruments offers unbeatable value for money. Using the ROTRONIC HW4-Light software that comes with the device, it can be set as required and data can be downloaded, saved and analysed.
Typical applications include indoor air quality studies, and safety studies in car parks.
