Technical characteristics
Checker Hanna pH analyser HI780
The HANNA HI780 pH meter, checker, is a digital colourimeter for pH testing. With the HI780 chlorine meter you can easily, accurately and cost-effectively measure pH.
The pH is a measure of the concentration of hydrogen ions in water. The higher the concentration, the more acidic the water. A neutral pH is 7 (most fish can live in a general range between 6 and 8). Keeping the pH of an aquarium stable and in optimal ranges reduces stress on your fish and aquatic animals, helping them resist disease and tolerate other stressors. Maintaining an ideal pH can also dramatically improve the growth, behaviour and overall appearance of marine life.
Designed as a more accurate alternative to test kits, the HI780 marine water pH meter provides fast, accurate results in a few easy steps.
The ideal pH in a pool should be between 7.2 and 7.4.
what's included?
The HANNA HI780 checker is supplied complete with two cuvettes with lids, liquid sample reagent, battery, instructions and a quick start guide for accurate measurement in a few simple steps.
Two bowls with lids
Liquid reagent
how is it used?

STEP 1. Zero the checker with your water sample.
STEP 2. Add reagent to the cuvette.
STEP 3. Insert the cuvette into the Checker.
STEP 4. Press the button and read the results.

HANNA checkers are small, portable and, above all, provide more accurate results than typical chemical test kits. Offering improved technology, their simple design allows for easy, uncomplicated measurement.
These digital photometers or test kits serve as a bridge between very simple test kits and professional instrumentation such as a calibrated photometer.
Conventional test kits are not accurate and depend entirely on the user viewing the colour, which is why HANNA has digitised this measurement and achieved accurate digital pocket colourimeters.
The innovative shape of the Checker makes it fit in the palm of the hand and in the pocket. In addition, the LCD display is easy to read, with an automatic shut-off function in case for some reason you forget to turn it off.
