    This easy to use instrument is a simple way of testing water for dissolved solids, which seems to be that standard way that quick tests are made to determine if water is potable. It does not provide a detailed analysis of the actual components contained in the water, but that is another story, The meter also measures the conductivity of the water, which is more or less the same thing, only measured from a different perspective.- i.e. the one can be calculated from the other using the appropriate formula. There is no need to be technical, since there is a backlight on the meter's screen: green means OK; red means not OK. As readings should strictly be taken at 25C, there is also a temperature measurement facility so that you can adjust the reading to take into account the temperature difference if you know the relevant coefficient (which I don,t). As a pure amatuer it more than does the job for me.

    Ricevuto nei tempi previsti, prodotto un pò economico costruttivamente ma nel complesso fa le funzioni previste, un pò per capire come si usa ma poi tutto ok.

    Received the items in a short period, I thought it will take a long time to reach me as it’s not shipped through express courier but I got with the same time the express courier might take and now I am using it at, hope I will get the needed result from this devise.
