Description
- Each Strip can be used many times – just put the strip somewhere dry and you can use it again!
- Four pads enable you to get a precise idea for the relative humidity of the room. It may take up to 15 minutes for the test pads to equilibrate or react completely.
- No chemicals, special preparations, or electricity needed to determine the humidity, just a strip and your eyes!
The Humidity test strip contains 4 blue test pads which is become pinkish according to relative humidity in the air. The process is reversible (i.e. the pads revert back to their original blue color). The test strip responds to the relative atmospheric humidity in the range of 20% – 80%, in the steps of 20 – 40 – 60 – 80%. You can learn more about how to use our humidity test strips and the science behind them.
Instructions:
Hold one test strip in the air or next to potential leaks. The blue indicator is discolored to pink according to relative moisture in the air. It may take up to 15 minutes for the test pads to react completely.
