Reads the actual humidity inside the pack, at a glance
A desiccant tells you nothing about whether it worked. An indicator card does: it sits inside the same sealed pack and reads the humidity the product is actually experiencing. Multi-spot cards give a graduated reading rather than a pass/fail, which is what you need when a specification calls out a particular RH threshold.
| Spot configurations | Single, three, four, six spot |
|---|---|
| RH ranges | 8%, 5–15%, 10–30%, 10–40%, 20–40%, 30–50%, 10–60% |
| Colour change | Blue → pink |
| Minimum order | 200 pieces |
The indicator reports its own condition — no weighing, no fixed replacement schedule.
