Product review (1 stars): Dissapointed with the performance of the product.
We have bought two items and when we turned on the equipment the data seemed to be good but when the relative humidity when above 80% the data changed from each item, one 94% and the other 83% to much difference for 2 devices in the same place, we also saw the error test but the equipment is new, we will check this product with our electricity technician and also will need to calibrate the product but it appears that it was not calibrated from factory.
