The Checker HC is a brand-new line of single parameter handheld colorimeters, designed to bridge the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain.  Checker HC's offer high accuracy and ease of use, in a small modern design that fits in the palm of your hand.

The Checker HC is now available in 5 different models. You can choose from phosphate, iron, free and total chlorine and iodine. Coming soon 3 new models, nitrates, nitrites, and bromine!

The contoured style of these Checker HC’s fit 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 Checker HC’s are extremely simple to use:
1.  Zero the instrument with your water sample.
2.  Add the reagent.
3.  Place the vial into the Checker HC, press the button and read the results. It’s that easy!

The new series of Checker HC’s are manufactured in our European state-of-the-art ISO 9001:2000 production facility. Each Checker HC is CE compliant to EN 61326-1 and EN 61010-1 standards.
