Low risk of false alarms because it equalises to the CO2 present in the air. Consistent and accurate responses – infrared cell does not weaken over time. Will not react to smoke, humidity, airflow or temperature changes. Quick ‘zeroing’ from high efficiency air sampling. On-board diagnostics indicate charging status and warn of low battery or infrared cell failure. NiMH power stick won’t corrode and provides greater charging capacity.
