Checkit Comparator — Comparator Disc Water Testing

Download pdf. Datasheets

Checkit Comparator - General

Description

Compact, one-piece housing with no moving parts to lose or break — the colour disc simply clicks into place and you're ready to test.

Covers a wide range of parameters, many with multiple testing ranges and methods; new parameters can be added at any time via additional discs and reagents, using the same comparator body

Continuous colour gradient on each disc gives a direct colour match against the sample — no need to interpolate between fixed standards

Diffuser panel behind the results window spreads light evenly across the sample and blank tubes, helping achieve an accurate match and compensate for turbidity

Clear, multilingual step-by-step instructions mean even non-chemists can get reliable, repeatable results quickly

Tablet reagents carry a guaranteed shelf life of 5–10 years
