This pocket-sized photometer is specially designed for the determination of alkalinity or KH in seawater (not suitable for freshwater). They are much more accurate than test kits and strips and the results are displayed digitally. They are light as a feather and therefore useful for measuring KH in seawater. No more messing around with test strips and comparing colors. Digital measurement is more accurate and very easy to read.
Economic, fast and accurate measurements
Very clear digitally readable display
Very easy to use with only one control button
Practically no maintenance
Automatic shutdown after 10 minutes
