Projects One Humonitor® Humidity Indicator Cards tell at a glance if moisture within sealed containers or closed spaces is at an acceptable level. Humonitor cards help monitor desiccant activity and are ideal for use with desiccants in any application where moisture control is critical. Any color change from blue to pink indicates an unsealed container and/or damaging level of humidity. |
Humonitor Humidity Indicator Cards have several distinct advantages:
- Easy to use and read for fast monitoring
- Wide range of indicating materials available which change colors at a variety of relative humidities - up to 100% RH
- Sensitive indicating element calibrated for permanent accuracy to ±5% of relative humidity
- Cards can be custom designed for your specific needs
- Electronics packaging
- Optical instrument packaging
- Preservation packaging of sensitive components
- Bulk packaging
