LaMotte Company’s WaterLink® Spin Touch™DW photometer automates home drinking water analysis, eliminating drop-count chemistry and user error. Water treatment professionals can now test eight different test factors simultaneously in 60 seconds with patented centrifugal fluidics photometry. No glassware or mess to clean. Users inject a water sample into a Spin Touch disk then load it into the instrument. All tests results appear on the touchscreen display and are time-date stamped into the instrument memory.
