Description
The CO2-Display is an inexpensive multiple parameter data logger that simultaneously measures and records CO2, humidity and temperature.Using the SW21 software that comes with the device, it can be set as required and data can be downloaded, saved and analyzed.
Applications of the CO2 data logger
Indoor air quality, monitoring in underground car parks (safety), Leak monitoring in filling plants (safety).

• 18 000 data point memory for CO2, humidity and temperature values
• Maximum, minimum and average value display
• Adjustable audible CO2 alarm
• Display with backlight
• Adjustable auto power off function
