DescriptionOMEGA’s HHWT-12 photometer uses the dip strip method and technologies that offer faster, safer, easier, and more precise water testing. The HHWT-12 has been designed to offer the user a more “green” and cost-effective alternative to testing. Instead of using a 10 ml water sample, it uses a 4 ml water sample, which uses up to 60% less chemical per test. The easy to use dip strip method delivers the reagents to the sample safely and takes the guesswork out of water testing. The HHWT-12 offers ten modes which provide direct read capabilities for nine direct reads: Total Alkalinity, Bromine, Calcium Hardness, Free Chlorine, Total Chlorine, High Range Chlorine, Copper, Ozone, Permanganate, pH, and % transmission–which allows for testing of an additional 31 parameters.
