AQD-V43[A] Desktop CO2 Monitor for Air Quality Control

ZKTeco's launches AQD-V43[A] an innovative CO2 Monitor for Air Quality Control designed for crowd control to help reduce the risk of Covid-19 transmission in indoor environments.

Monitoring carbon dioxide levels in buildings and common areas correlate to mitigate the coronavirus threat. The new series of ZKTeco CO2 Monitors enables continuous monitoring of carbon dioxide concentration in the air helping to control the air quality. When the measured level of carbon dioxide rises above a threshold, an alarm is triggered, and appropriate security actions can be taken.

This new series of CO2 Monitors are simple to fit and easy to maintain, and they do not require any particular installation or wiring. A precise and cost-effective solution for residential, commercial, offices, restaurants, and official buildings.
