Humidity Test Strips
Current Reviews: 1
Wait at least 15 minutes before recording the humidity level. The vial is lined with dessicant and the strips need time to equilibrate. The 20% will change first, followed by the others. Note that these pads are reversible, changing color to white - pink and back to blue repeatedly, according to ambient humidity.
