Product review (1 stars): view window easily scratches. RH/DP way off
Only used product twice in crawlspace. Casing is weak, view window easily scratches. RH/DP way off. Should come calibrated. Should include calibration canisters for calibration, instead there's an addition charge for that item. I will be  returning this product. I could see it may be useful to some industries, but not for contscko
