CP11

The CP11 handheld instrument is an economical multiple parameter meter 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 SW21 software that comes with the device, it can be set as required and data can be downloaded, saved and analyzed.

Applications
Indoor air quality, monitoring in underground car parks (safety), Leak monitoring in filling plants (safety).
