Description
The HI775 handheld colorimeter provides a simple, accurate, and cost-effective way to measure alkalinity.
Get accurate water analysis results with our easy-to-use handheld colorimeter. Our freshwater alkalinity colorimeter gives you more accurate technology from your standard chemical test kit. With direct digital freshwater alkalinity results, our handheld colorimeter eliminates the hassle of color matching.
Present in varying concentrations in freshwater bodies, the alkalinity of carbonated and non-carbonated salts provides a buffer against drastic pH changes in water. Used in the drinking water treatment process, the concentration of alkalinity dictates which chemicals are used and in what volumes,
as well as protecting the finished drinking water in the distribution system
-Dedicated to a single parameter-Small
size, great convenience-Easier
to use and more accurate than chemical test kits-Easy
operation and direct results make measurement fast
How to use it?
Designed as a more accurate alternative to chemical test kits, the HI775 provides fast and accurate results in a few simple steps:
STEP 1. Zero the checker with your water sample.
STEP 2. Add the reagent to the cuvette.
STEP 3. Insert the tray into the Checker.
STEP 4. Press the button and read the results.

Method Colorimetric Method
HANNA checkers are small, portable and, above all, provide more accurate results than typical chemical test kits. Offering improved technology, its simple design allows for easy measurement without complications.
These digital photometers or test kits serve as a bridge between the very simple test kits and professional instrumentation such as a calibrable photometer.
Conventional test kits are not accurate and depend entirely on the user who is viewing the color, which is why HANNA has digitized this measurement and achieved accurate pocket-sized digital colorimeters.
The new shape of the Checker makes it fit in the palm of your hand and in your pocket. In addition, the LCD screen is easy to read, with an automatic shut-off function in case for some reason you forget to turn it off.
