- Operates with high accuracy and reliability down to temperatures of -20°C. Performance may degrade below -20°C
- Extended exposure to concentrations below 400 ppm may result in incorrect operation of ABC algorithm and should be avoided.
- Sensor provides readings in the extended range but the accuracy may be lower than that specified in the table.
- The accuracy specification covers environments ranging from 0-50°C and 0-80% RH, and complies with indoor air quality standards ANSI/ASHRAE Standard 62.1-2022 at 25°C.
- Temperature response times strongly depend on the type of heat exchange, the surrounding surface and the airflow in the final application environment.
- As a RESET Certified Grade B air quality monitor, this device automatically meets technical requirements for this parameter.
- Humidity response times strongly depend on the surrounding surface and the airflow in the final application environment.
- Total length of cabling up to 100 meters. However, we don’t recommend using cables longer than 50m to guarantee the stability of power and data transmission.
- Customizable upon request.
- Optional extended warranty with contract.
