Product BrochureThe EE820 CO2 sensor is optimized for use in harsh, demanding applications, such as hatchers, incubators, life stock barns or greenhouses. Outstanding Accuracy A multiple point CO2 and temperature factory adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range, so the EE820 can even be installed outdoors. Long-term Stability The EE820 incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability. High Resistance to Pollution With its robust, functional IP54 enclosure with a special filter the EE820 can be employed even in harsh environment. Fast Response Time For an even lower response time, a forced air circulation module is available as an accessory. Analogue Output The CO2 measured data range up to 10000 ppm is available on the analogue output (voltage / current). Easy Configuration and Adjustment An optional adapter and the free EE-PCS Product Configuration Software facilitate the configuration and adjustment of the EE820

Product BrochureThe CO2 Guard 10 reliably shows the carbon dioxide (CO2) concentration in the ambient air as a measure for indoor air quality (IAQ). The CO2 level indicated by the LEDs helps deciding on the need for ventilation, for example by opening the windows. Adequate ventilation and IAQ is paramount for healthy living and working conditions. In spaces with high occupancy, good IAQ diminishes the risk of contamination with aerosol-borne diseases. Addditionally, air exchange based on the actual CO2 level can significantly reduce energy costs compared to random ventilation. Measurement performance The CO2 Guard 10 employs the dual wavelength NDIR measurement principle with auto-calibration, which stands for outstanding long term performance even in harsh and polluted environment. Pressure and temperature compensation with on-board sensors lead to best accuracy irrespective of the location (altitude), weather and environmental conditions. Flexibility The CO2 Guard 10 can be deployed as wall mount or as portable tabletop device. The tabletop stand adapter is included in the scope of supply. Comfortable use The CO2 Guard 10 is maintenance free. Battery supply allows for portable use independently of any external electrical supply availability. All LEDs flashing indicate the need for replacing the batteries. Visual and acoustic indication Green, yellow and red LEDs indicate the actual CO2 range. Additionally, short acoustic signals indicate CO2 rising to the next higher range. Wide CO2 monitoring range The six CO2 ranges indicated by the LEDs are suitable for all common indoor situations from low to high CO2 levels. Low CO2 levels are typical for residential and commercial purposes according to EN 13779. High CO2 levels typically occur in spaces with very high occupancy such as school classes. Long battery life time A set of 4 commercially available batteries lasts for typically 6 months at room temperature. The snap-on enclosure concept allows for opening/closing without any specific tools.

The EE046 condensation monitor helps to prevent condensation on critical cold spots. It reliably detects the danger of condensation just before it occurs with the help of its relative humidity (RH) sensing element. Mounting options EE046 is available in two variants. The wall mount/pipe mount model is appropriate for installation on flat surfaces and on pipes with a maximum diameter of 50 mm (2"). It is mounted on cooling ceilings, on cooling or cold water piping, cooled surfaces and chilled beams. The snap-on model can be mounted on plastic and aluminium composite pipes with 16 mm or 20 mm diameter. Typical applications for this model are cooling and heating by concrete core activation. Reliable anti-condensation safe guard Condensation on a surface occurs when the humidity of the air close to the surface reaches 100 %. Because of the very good thermal coupling with the surface, the EE046 measures the RH of the air directly at surface temperature. Its properties make it the ideal choice for applications where control guards are required to prevent dripping or mould. Early detection of condensation risk The relay output provides an early warning before condensation actually happens. It also indicates a power supply failure or a broken cable. A status LED indicates normal operation, alarm or power supply failure.The E+E proprietary coating protects the humidity sensor against dust and dirt.
