The Pool Lab 3 Bag Reagent Set is a refill pack of testing reagents for photometer-based pool water testers, including Pool Lab, Chromatalyzer, ASP, Hayward, PL and Puresilk systems. It's designed for pool owners and technicians across Australia who rely on accurate, lab-style water readings rather than test strips or drop kits.

What's included

• Three reagent bags formulated to work with compatible photometer water testers
• Consistent, repeatable results for key pool chemistry parameters
• A straightforward refill for testers that have run through their original reagent supply

Why it matters

Accurate reagents are the difference between a photometer giving you a true reading and one that leads you to over- or under-dose chemicals. Keeping fresh, compatible reagents on hand means your pool testing stays reliable through the swimming season.

Always check that this reagent set matches the make and model of your existing photometer before ordering.
