Humidity Indicator Card
It is a good idea to monitor the climate in
storage areas to ensure that it remains moderate and stable. Monitoring
instruments ranging from humidity indicator cards to hygrothermographs and data
loggers are available. While we do not sell equipment like hygrothermographs, we do sell humidity indicator cards.
The simple card, which can be recharged, shows 6 indicators that changed from blue to pink and will read what the prevailing humidity is in the closed space. Easy to read with instructions on each card.
Read between 10%, 20%, 30%, 40%, 50%, and 60%.
