Product Specs
OMEGA’s HHWT-11 is a handheld photometer designed for direct read testing water for free and total chlorine. The HHWT-11 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-11 also features a transmission mode which allows users to develop custom conversion charts using general tablet and power methods.
