Relative humidity indicators handle diverse levels
A
Brownell product story
Edited by the Engineeringtalk editorial team
Jul 22, 2008
Relative humidity indicators can provide an indication of when the desiccant is saturated and requires replacement or recharging.
Brownell manufactures a range of relative humidity indicators which provide a signal of the relative humidity ranging from 10% to 60%.
50% relative humidity is a typical level obtained to prevent damage to products and components.
Semiconductors and hygroscopic powders often require relative humidity levels as low as 10%.
Relative humidity indicators can also be used in conjunction with desiccators, desiccant bags and moisture absorbers to provide an indication of when the desiccant is saturated and requires replacement or recharging.
Humidity indicators can also be used to monitor the relative humidity inside cabinets storing antique items where low and high humidity can cause irreparable damage.
A blue to pink colour indicates the transition of the relative humidity from dry to wet.
Relative humidity indicators are fully reversible and will change colour when dried with a desiccant or placed in a dry environment.
Relative humidity indicators can be fitted to panel mounting housings for viewing the internal relative humidity of an instrument or system.
Multiple level relative humidity indicator cards are commonly used for packaging applications.
Relative humidity indicators are available in a range of sizes for easy visibility when used inside a plastic storage bag or transit container.
