Have the MT-3 at 17.3. put in my film greenhouse. The cable of the outdoor sensor was 3 cm less than the specified 1.50 m. The MT-3 shows the temperature and humidity of good. In plastic greenhouse were 99% humidity. The last 3 days were cool. Today, the visible housing was then fogged from the inside. Actually, the MT-3 should (also with high humidity) also for the sauna. Well, have the MT-3 now mounted upright on the bar and since it is now nice and warm, opened the entrance of the foil greenhouse. I hope if the window again gets fogged, I can reduce the star of 3 to 2. But we are only once optimistic. What also stands out when I press the max key and to hold back, sometimes the temperature from Celsius to Fahrenheit change. When inserting the battery there is no rubber seal for the purpose of protection against moisture. So let's see you next week. For those who have less than 50%, or for a short period to do with more humidity, the MT-3 is likely to be ideal. If would not have been an extra in the product description that it would be suitable for the greenhouse, sauna, cold store or refrigerator, stands up probably 5 star.
Addendum on 03/25/14: yesterday I was able to reduce from 3 to 2, as steam up more than 80% humidity, the viewing window. In contrast to the product is clearly in the English instructions that the thermometer is only for indoor use. That the external sensor into the aquarium, refrigerator etc. can be hung into it, right in my view not generally declare this product for damp areas.
