Air sample
I bought this unit for this unit after comparing to 12 other meters. It measures twice a second, at 2.5% accurate with a cost of 20% of other machines at 2% accuracy. Indicates 5 different samples including RH, temp, noise, light, and air flow at the press of a button. Only reason for not giving a perfect 5 stars is I have only had it 3 weeks.

Great all-around meter
I bought this one month ago both for light consulting use and teaching 1st year engineering students. Luminance is a nice touch. Very happy so far.
