Drinking Water Alkalinity Checker (0 to 500 ppm)

The pocket meter for alkalinity in drinking water, the HANNA HI775 checker, is a digital colorimeter for performing alkalinity tests. The HI775 Drinking Water Alkalinity Checker is supplied with two cuvettes with a lid, reagent for 25 tests, battery, instructions and a quick-use guide so that with a few simple steps an accurate measurement can be achieved. The alkalinity of water is one of the most important parameters to measure in aquariums as it helps to maintain a stable pH, a very important factor for most aquatic life.The alkalinity of water can be defined as a measure of its ability to neutralize acids. In natural waters, this property is mainly due to the presence of certain salts of weak acids, although the presence of weak and strong bases can also contribute. These substances act as buffers to resist the drop in pH resulting from the addition of acids. This concept is widely used in wastewater treatment practice.The concentrations of certain species (hydroxides, carbonates and bicarbonates) produce a buffer effect in the water since they absorb protons, keeping the pH at a stable value. This is very important in living beings and in certain environments such as blood flow. It is also worth noting that water with high alkalinity is not necessarily harmful for human consumption, such as carbonated water, also known as soda. The new HI 775 meter is a simple, accurate, and inexpensive way to analyze this parameter. It is designed as a more accurate alternative to test kits. Alkalinity test results are obtained in four easy steps. Step 1: Add a sample to the cuvette (included). Step 2: Insert the sample into the checker and press the button to zero. Step 3: Remove the sample and add the reagent as directed in the manual. Step 4: Reinsert the sample and press the button to measure the results. The HI775 Drinking Water Alkalinity Meter (0 to 300 Ppm) is ideal for freshwater aquariums.HANNA checkers are small, portable and, above all, provide higher precision results than typical chemical test kits. Offering improved technology, its simple design easily allows for hassle-free measurement. 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 precise and totally depends on the user who is viewing the color, which is why HANNA has digitized this measurement and has achieved an exact pocket digital colorimeter. The Checker® is accurate while offering a very affordable price. The new shape of the Checker makes it fit in the palm of your hand or 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. Easier to use and more accurate than visual test kits: • High precision • Large, easy-to-read digits • Automatic shutdown Dedicated to a single parameter: • Designed to work with Hanna's reagents • Uses 10 ml glass cuvettes Small size, great comfort: • Weighing only 64g, the Checker® fits easily in your hand or pocket Use it for quick and accurate analysis Single button operation: zero and measure Operated by a single AAA battery General.
