Hanna 8-Parameter Water Test Meter
Hanna C203 8 - Parameter Water Test Meter The following meters work using ion specific chemical method, in other words like simple test kits, a chemical is added and a colour is formed and the electronic meter reads the results very accurately in mg/l down to 2 decimal places I.E. 0.01mg/l special reagents (chemicals) are required for each parameter.  This Complete Kit C203 is sound value and is in our opinion better value than the individual iron specific Meters if you can afford the initial layout ... This comes complete with the 5 major test reagents: - pH, Ammonia, Nitrite, Nitrate, Dissolved Oxygen. There is enough reagents supplied to perform 100 tests How they work? There is no need to calibrate as the test procedure does this for you. Fill the test tube with a clear pond water sample, insert into meter, press the “zero” button (this calibrates the pond water sample to the meter as a reference), add the reagent to the same test tube, Insert back into the meter, press the read timer button, this starts a timer count down, then the meter shows the result on the digital display. All have a 2 year warranty.
