Colorimetric testing is a method of determining the concentration of a chemical element or compound (organic or inorganic) in a solution with the aid of a colour reagent.

Using Hanna special reagents, our test kits measure the strength or weakness of a chemical presence according to the degree of colour saturation. Ie – if it is pale in colour, then the chemical concentration is low. If the colour is strong, then the chemical concentration is high. Simply add the reagent to the compound to be tested and match the colour gained against a colour chart included in the kit.

HI-3830 Bromine test kit

SKU: HI-3830
  • The HI-3830 portable bromine test kit determines the bromine level in water with efficiency. The first step involves pH adjustment of the sample to pH 6.3 by adding pH buffer. The second step consists of adding the second reagent, an indicator solution which contains DPD (N, N-diethyl-p-phenylenediamine). DPD is immediately oxidised by bromine producing a reddish colour. The colour intensity of the solution determines the bromine concentration.
