pH/Chlorine Photometers

The EZ photometric instrument is a battery operated unit offering high accuracy measurement of Chlorine, pH and Bromine or Cyanuric Acid. It uses the standard DPD 1 or DPD 3 method for Chlorine and pHENOL RED for pH. The measured value is displayed on an easy to read LCD. The instrument is totally waterproof and is supplied in a carrying case with all reagents.

Measuring Ranges:
Chlorine, Free 0 - 6 mg/l
pH 5.9 - 8.2 pH
Cyanuric Acid 5 - 90 mg/l

Instead of tablets the EZ uses the EXact reagent strips which are supplied in bottles of 50 strips for the above tests. Other versions of the EZ are available for the measurement of other parameters, e.g. Bromine, Chlorine Dioxide

Colour Comparators

Less accurate but inexpensive method of measuring Chlorine and pH is an optical colour comparator where stable coloured solutions are created by the addition of reagent tablets and compared against known standards. Comparators are available for: Chlorine/pH Bromine Hydrogen Peroxide (Sanicil) Most kits are supplied with sufficient tablets for 30 tests.What's another popular item you have for sale or trade?

Test Strips

An inexpensive method of testing for a wide range of chemical parameters is by using dip strips. The chemically impregnated tip of the measuring strip is dipped into the test solution for a few seconds and on removal produces a colour which is compared against a colour chart to determine intensity levels.

  • Chlorine Low Range 0-10 ppm
  • Chlorine High Range 0-200 ppm
  • Hydrogen Peroxide Low 0-100 ppm
  • Hydrogen Peroxide High 0-400 ppm
  • pH 2-12 pH
  • QAC (Sanispray) 0-400 ppm
  • Multi pH, Chlorine, Hardness. Various

Test strips available in vials of 50 or
