trodeks’s HHWT-12 photometer uses the dip strip method andtechnologies that offer faster, safer, easier, and more precise watertesting. The HHWT-12 has been designed to offer the user a more“green” and cost-effective alternative to testing. Instead of using a10 ml water sample, it uses a 4 ml water sample, which uses up to60% less chemical per test. The easy to use dip strip methoddelivers the reagents to the sample safely and takes theguesswork out of water testing. The HHWT-12 offers ten modeswhich provide direct read capabilities for nine direct reads: TotalAlkalinity, Bromine, Calcium Hardness, Free Chlorine, Total Chlorine,High Range Chlorine, Copper, Ozone, Permanganate, pH, and% transmission–which allows for testing of an additional31 parameters.
