Wayne; Hanna makes a single frequency spect for about $150.00 and the chemicals for 50 tests is about $105.00. You will need several other items which I will not go into here. If anyone is interested in buy the Hanna unit I will help them get started. It is not difficult but time consuming to establish a base line for testing.
If one does not keep the wet electrodes polished then things will not always be the same. For example I had been running 2 gallon lots with my HVAC unit and getting 15 ppm in 2 1/2 hrs. Suddenly the 2 1/2 hr run produced 5 ppm!! the wet anode was covered with a white film. After cleaning with a scrubbie things returned to normal.
