Technical characteristics
Checker Hanna total analyser HI711
The HANNA HI711 total chlorine checker is a digital colourimeter for chlorine testing. With the HI711 chlorine meter you can easily, accurately and cost-effectively measure total chlorine.
The benefits of chlorine on water are many and it is precisely these benefits that make the use of this product so important both in drinking water tanks and in the maintenance of swimming pools. First and foremost, it is a powerful germicide, reducing the level of pathogenic micro-organisms in the water to levels that are almost impossible to measure. Chlorination allows the control of taste and odours by reducing them, this is due to the fact that chlorine oxidises substances that occur naturally, we are referring to the secretions of smelly algae and odours of vegetation that is in the process of decomposition; chlorine gives water odourless attributes and favourably modifies its taste.
what is included?
The HANNA HI711 checker is supplied complete with two cuvettes with lids, reagent powder for 6 tests, battery, instructions and a quick guide for use so that with a few simple steps you can achieve an accurate measurement.

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.
