30-40-50% humidity indicators for shipping

These indicators show whether ambient humidity has crossed the 30, 40 or 50 percent thresholds during transit. Each card changes colour permanently so receivers can confirm storage conditions at a glance. The pack contains 125 cards for high-volume packaging operations.

Verify card size and threshold range needed

Each card measures two by three inches and displays three fixed points at 30, 40 and 50 percent relative humidity. Check that these dimensions fit your packaging and that the three-step scale matches your quality-control requirements before ordering.

Passive operation with no power or noise

The indicators use a chemical reaction that requires no electricity, generates no heat and makes no sound. They remain accurate across normal warehouse temperatures and add negligible weight to shipments.

What does the 30-40-50% reading tell me once the card is inside a sealed package?
