Bridge the gap between simple chemical test kits and professional instruments with this Hanna® Checker® Handheld Colorimeter, Phosphate. Chemical test kits are not very accurate and only give 5 to 10 points of resolution, while professional instruments can cost hundreds of dollars and can be time consuming to calibrate and maintain.
This device uses a 525-nm-wavelength LED light source and a silicon photocell detector to deliver high-accuracy, low-cost results. It's contoured to fit in your palm and pocket perfectly and has a large easy-to-read LCD. Auto shut-off maximizes battery life. Unit comes with two 10-mL sample cuvettes with caps, reagent powder for 6 tests, AAA battery, and instructions.
