The Hanna Instruments HI720 Calcium Hardness Colorimeter - CheckerHC is the perfect tool for anyone looking for an accurate and efficient way to test their water's calcium hardness. Say goodbye to traditional chemical test kits that rely on the human eye to match colors and hello to this handheld colorimeter that provides a direct calcium hardness result digitally. With a range of 0.00 to 2.70 ppm and a resolution of 0.01 ppm, you can get simple and direct results with just one button.
This advanced instrument offers a middle ground between high-end instrumentation and standard test kits. It eliminates the hassle of matching to a color chart by providing a direct calcium hardness result digitally, greatly increasing accuracy and efficiency. The device is based on the adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, Calmagite method. The reaction between calcium and reagents causes a reddish-violet tint in the sample, giving you an accurate reading.
The device features LED light source at 525 nm and a silicon photocell light detector, making it incredibly precise. Its auto-off feature kicks in after ten minutes of non-use, saving battery life. The device runs on a single 1.5V AAA battery and can operate within a temperature range of 0 to 50°C (32 to 122°F) with a maximum relative humidity of 95% non-condensing.
The device comes in small, portable dimensions of 86.0 x 61.0 x 37.5 mm (3.4 x 2.4 x 1.5”) and only weighs 64g (2.3 oz). The HI720 CheckerHC is supplied with sample cuvettes with caps (2), calcium hardness reagent starter kit (reagents for 25 tests), syringes with tips (2), a plastic beaker, battery, instructions, and a quick start guide. It has a one-year warranty.
This device is the go-to choice for anyone concerned with the hardness of their water. It offers a direct, accurate, and simple way to measure calcium hardness in your water without the difficulty of matching to a color chart. Say goodbye to inaccurate color matching with this easy-to-use device.
