Looking at the link, this device measures formaldehyde in mg/m3. You'll need to convert this to ppm, just FYI.

1 ppm in air = 1.24 mg/m3 @ 25° C

If you're measuring 0.1 on the meter, that's about 0.08ppm (still pretty high).

It can show the measurement in ppm also.

However, I've read the reviews and dug a bit deeper, talked to some people. Basically, that value might be elevated by some unknown amount, but the device should not be trusted for the absolute levels.
