The Oakton PTSTestr 50 hand-held meter, donated by the Mabel Lake Community Club, tests a water sample for pH, Conductivity (EC), Total Dissolved Solids (TDS) and Salinity. We rarely use it for salinity because we are sampling fresh water.
Unlike the Hach meter, this meter does not maintain a record of its readings.
