A semi-quantitative test strip for ozone in air rather than in water. Dip it, wait the stated time, and compare the pad against the colour scale on the tube.
Ozone generators leak, and ozone is an irritant that damages the lungs at concentrations well below what most people would call a smell. A test that samples air rather than water answers the question that matters to whoever works in the room.
A strip gives a range, not a figure. That is enough for the great majority of decisions — dose or do not dose, discharge or hold, keep running or stop — and it gives the answer where the sample is, in about a minute, with no instrument to calibrate and nothing to carry back to a laboratory.
When a number has to be defensible — a regulatory report, a dispute, a limit you are close to — a photometer or a laboratory method is the right tool. The strip's job is to tell you whether you need one.
This is a spot check, not personal exposure monitoring; where exposure is regulated, a dosimeter or an instrument is required.
Supplied in one presentation.
