What it is

The working details

The AK11T With Infrared CO₂

Same 98 × 32 × 67 mm shell and 50-per-carton spec. The semiconductor CO₂ element becomes infrared NDIR — the step that turns a trend indicator into a figure you can quote.

Readings That Stay Comparable

Infrared measurement does not age the way a semiconductor element does, so a figure taken next winter can be set against one taken today.

Unaffected by What Else Is in the Air

Alcohol, solvents and cooking vapour move a semiconductor CO₂ reading. They do not move this one.

1200 mAh, 6–8 Hours

213 g, USB-C, about three hours to full charge.

The Accuracy Tier of the AK11 Family

Same shell and carton spec as AK11T; the upgrade a distributor offers when a customer asks how accurate the number is.
