JEDEW 2 Pack Mini Digital Hygrometer Thermometer Gauge, Indoor Outdoor Temperature Humidity Meter for Greenhouse Humidors Incubators Reptile Terrarium Jars, Fahrenheit (℉) or Celsius(℃) (2)

I was a little doubtful but I bought them, I placed them in my cigar humidor, there are always fresh boveda 67% humidty packs in there. These hygrometers read 68%, both have the same reading. So they seem to be accurate.I like the size as well, they don't take up much space.

These are fine little devices for the price, but when they arrived, one had a completely dead battery and the other had no battery at all. Other than that they're OK for the price.

Funcionan bien y están bien calibrados. Las mediciones son iguales a mis sensores de temperatura externos. Buen precio. Útiles para cajas de secado de filamento

Otimo produto bonitinho chegou bem embalado, vem com 2 baterias

Mit dem entsprechenden Ausdruck für das AMS fügt es sich dort sehr gut ein und gibt wichtige Informationen über die Temperatur und die Luftfeuchtigkeit im AMS. Prima!
