The HANNA Alkalinity Checker bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and have low resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA Alkalinity Checker is accurate and affordable.
The HANNA Alkalinity Checker features an accuracy of ±5 ppm (mg/L) ±5% of reading and uses the colorimetric method.
The contoured style of this Alkalinity Checker fits in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.
The HANNA Alkalinity Checker is extremely simple to use. After zeroing the instrument with your water sample, add the reagent to the cuvette and gently invert 5 times. Then insert the cuvette into the HANNA Alkalinity Checker and press the button to read the results. It's that easy.
