- 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.
- As a RESET Certified Grade B air quality monitor, this device automatically meets technical requirements for this parameter.
- During operating hours (9-5, Mon-Fri): one sample per minute for all sensors except particulate matter, and one sample every 10 minutes for particulate matter. Outside of operating hours: one sample every five minutes for all sensors except particulate matter sensor, and one sample every 60 minutes for particulate matter.
- Actual battery life may vary based on usage, environmental conditions, and other factors. Model SE-300W has a battery life expectancy of 3.5 years. Model SE-300L has a battery life expectancy of 8.5 years.
