Ideal for monitoring environmental conditions (temperature, humidity and dew point) in laboratories, storage areas, manufacturing assembly areas and other controlled environments, the humidity alert meter features a user settable alarm and will warn you, both audibly and visually, when adverse conditions occur. High humidity can create a breeding ground for mold and low humidity can create static electricity. The 445815 also displays the dew point reading which is a calculation of temperature and humidity and used to determine when condensation will occur. The humidity alert meter ...
