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.

NIST Certified? Comes with Certificate of calibration (COC)? Where to send to for annual certification/ or calibration?. What kind of calibration do you provide? Can we have more T&RH calibration data points .
Hi Amador,
Thank you for the inquiry. The RH87 does not include NIST certification. It comes with CofC. Please contact our Customer Care if return for calibration pricing is needed.
Our calibration is ISO9001 certified. Please contact our temperature engineers if special test points are needed.
Best regards
OMEGA
