Five-sensor air monitor for home and travel

The PinoTec AK3 measures carbon dioxide, formaldehyde, TVOC, temperature and humidity in one compact Ink Grey unit. A 1200 mAh rechargeable battery powers continuous monitoring without a permanent outlet. It suits anyone who wants immediate visibility of indoor pollutants in bedrooms, offices, cars or temporary accommodation.

Colour screen shows safety levels at a glance

The LED display changes colour to flag unhealthy readings so you can react without interpreting raw numbers. Battery operation limits use to the charge cycle; extended sessions away from USB power will eventually require a recharge. No audible alarm is fitted, so visual attention is necessary.

Verify USB charging access and placement height

Ensure a USB port or adapter is available for periodic recharging of the 1200 mAh cell. Position the monitor at breathing height and away from direct drafts or heat sources to keep CO2, HCHO and TVOC samples representative. The device arrives ready to use with no separate batteries required.
