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.
