What it is

The working details

The AK25A With Infrared CO₂

Same 98 g mini body, same five readings, same packaging. The CO₂ channel moves from a semiconductor element to infrared NDIR — the smallest body in the range carrying it.

Stable Where Semiconductors Wander

Humidity swings, hand sanitiser and cleaning products leave the reading where it is. The figure you take this month is the figure you can compare next month.

Five Readings on a Mini Body

CO₂ by NDIR, TVOC and formaldehyde by MOS, plus temperature and humidity.

1200 mAh, Six Hours

Four-hour USB-C charge.

Same Footprint as AK25A

Identical enclosure and packaging — the accuracy tier without a second carton specification to manage.
