Testpak The Testpak is a simple and cost-effective means of extending the use of an existing CHECKIT®Comparator instrument to a new test parameter. *Reagents for turbidity method and speed test (Test-Kit 5 in 1) see MINIKIT. All test kits for chlorine are for 'free, combined and total chlorine”. Test Kits 2 in 1 Order Code pH value 6.5 - 8.4 pH Copper 0 - 1.0 mg/l Cu pH value 6.5 - 8.4 pH Test Kit 5 in 1 Chlorine 0 - 4.0 mg/l Cl2 pH value 6.5 - 8.4 pH Cyanuric acid (Turbidity method)* 20 - 200 mg/l Cys Calcium hardness (Speed-Test)* 20 - 800 mg/l CaCO3 Total Alkalinity (M) (Speed-Test)* 20 - 800 mg/l CaCO3 Disc readings see following pages. The operating instructions provide a step-by-step explanation of how to conduct the water test, ensuring that even 'nonchemists” can achieve reliable and accurate measurements in the minimum of time. The test kits are supplied in a sturdy and handy plastic case. Test Kits Together with the CHECKIT®Comparator, each test kit includes CHECKIT®Discs, cells, stirring rod and AQUALYTIC® tablet reagents (for 30 tests) for the desired test. Instruction manuals explaining the various stages of analysis in simple, straightforward terms, are supplied with each CHECKIT®Disc. These CHECKIT®Discs are specially manufactured in selected materials to remain colour-stability over a long period and guarantee reliable, reproducible measurement results. CHECKIT®Disc Each CHECKIT®Disc contains a continuous colour scale which makes it possible to achieve an exact colour match between the colour standard and the sample. The mirror optics makes use of the view through the entire length of the cell.

The CHECKIT®Comparator D55 enables the use of large path lengths. Supplied with a generous number of different colour scales, it provides the basis for a comprehensive, easy-to-use colorimetric analysis system.

CHECKIT®Comparator The AQUALYTIC® CHECKIT®Comparator is a compact, handy colorimetric unit which is suitable both for mobile and stationary analysis work.
