Description

These are the AquaChek TruTest test strips, 100 to a bottle. They are the refill strips for the TruTest digital test strip reader, which reads the strip electronically and reports free chlorine or bromine, pH and alkalinity as numbers.

Why a reader instead of a chart

Reading a strip against a printed color chart is where most home testing goes wrong. Light, shade and eyesight all change the answer. The TruTest meter takes the reading itself, so two people testing the same water get the same result.

Using them

Dip a strip in the pool or spa, put it into the meter and read the values. The bottle has a flip top cap so it opens with one hand and closes again quickly, which matters because damp strips give bad readings. Test at least twice a week, taking water from each end of the pool.
