aquapro digital water tester (tests water conductivity)

Description Documents Specifications Description Before You Install a Steam Humidifier, Test Water Conductivity! Installing a steam humidifier can be one of the most effective ways of increasing the humidity in one’s home; however, selecting the right model requires a little more consideration than other humidifier models! Steam humidifiers utilize electrode steam technology, whereby electric current is passed between electrodes inside a water-filled canister to heat the water within and create steam. This technology relies on water conductivity (provided by the presence of natural minerals in the water) in order to efficiently pass electric current between electrodes. Knowing your water's conductivity is essential in determining which model steam humidifier you should install. If the water does not have ample conductivity, steam humidification may not be the right choice for your home. Testing Water Conductivity: Using the AP-2 Digital Water Tester, test your tap water for electrical conductivity (measured in micro Siemens per centimeter (µs/cm).
