Description

The LaMotte R-2057 is the test reagent refill kit for the ColorQ PRO 7 pool water tester. It restocks the chemistry the meter uses so an existing tester keeps working.

What it is

This is a refill, not a tester. It suits an owner or service tech who already runs a ColorQ PRO 7 and has worked through the reagents that came with it.

Why refills matter

Test chemistry is consumed with every reading and loses accuracy as it ages. A photometer is only as good as the reagents in it, so keeping fresh chemistry on hand is what makes the readings worth trusting.
