Micro Essential CMR-245 Test Paper Refill 10-200 ppm PK10

Test Paper Refill for Free Chlorine

The Micro Essential CMR-245 refill pack supplies ten rolls of test paper designed to measure free chlorine levels from 10 to 200 ppm. Each roll is 15 ft long and 1/8 in wide, providing enough material for approximately 2,000 individual tests. The pink and white PVC strips include a matching colour chart for immediate visual comparison. This product suits pool operators, water-treatment technicians and facility managers who need a portable, reagent-free method for routine disinfection checks.

Integrates with Standard Test Kits

The refill rolls drop directly into compatible chlorine test kits, replacing spent paper without tools or recalibration. Because the strips are self-contained, they free the user from carrying liquid reagents, vials or a photometer when moving between sampling points. The compact 15 ft rolls store easily in a toolbox or glove compartment, ensuring a fresh supply is always at hand for spot checks or scheduled compliance rounds.

Consistent Response Under Repeated Use

Each strip delivers a stable colour reaction across the full 10 to 200 ppm range, maintaining readability during extended testing sessions. The PVC substrate resists curling and fraying even after prolonged exposure to humid environments, so the last test on a roll performs like the first. This reliability supports high-volume monitoring programmes where dozens of measurements are taken in a single shift.
