The CO₂ monitors offer an LCD screen that clearly relays the measured values in PPM (particulates-per-million) and indicates good, normal, and poor air quality levels. Integrated into the devices is an acoustic alarm that sounds off when levels defined have been exceeded. Additional features include the year, month, date, and time plus the monitors are power via a battery or plug adapter.
