The humidity section worked great; but the temperature section gave shorted fault to the input on the Novar IOM/2.
The ma reading confirmed this and I never could get that part to work. Guess I need to order separate temp next time.
Pros: Good value, humidity works
Cons: Low value, temperature doesn't work

We use the wall mount version, and it worked as expected since the begining. It's a very good alternative to Vaisala when you need pecition, and also has NIST.
Pros: Good value
Yes, I recommend this product.
