Description
Key Features
Dual display functionality allows you to monitor CO2 concentrations and environmental factors like Temperature, Humidity, Dew Point, or Wet Bulb simultaneously.
The maintenance-free NDIR (non-dispersive infrared) CO2 sensor ensures reliable air quality readings without the need for frequent sensor servicing.
An integrated audible CO2 warning alarm alerts you immediately when concentration levels exceed your custom high user set point.
Track environmental changes easily using the Min/Max CO2 value recall function to see the highest and lowest levels recorded.
Convenient user controls include a Data Hold function to freeze readings and an Auto Power Off feature to help conserve battery life.
Stay informed about your device status with a built-in low battery indicator to ensure you are always ready for testing.
