Use these in my storage and guitar playing rooms to compliment the smaller RHM15 in my guitar cases

5.0

This is essentially the same review I've submitted for 7 of the RHM15 models I use in my guitar cases - purchased 2 of these for the larger display. In short, these are CONSISTENTLY accurate, both relatively to actually humidity - and even more so: the actual humidity reported. These 2 units plus 6 of the 7 RHM15s report exactly the same reading, the one other is only 1 degree off --- I have never seen or heard of such phenomenal accuracy from those of us that use them in our homes and guitar cases. I just provided this larger one and the RHM15 as gifts to my guitar instructor of over 10 years. And so reported the precedented accuracy to my local, high-end guitar store. I purchased this model for the larger batteries, and that it could be calibrated with accessory kit - but, in my use, clearly not needed given the exact accuracy of all the meters.

Unrivaled accuracy - seriously - the best for my use on Dec 30, 2021 I found this helpful (0)
