Humidity Indicators

Humidity indicators allow you to visually check whether a product or package has been exposed to humidity levels above the permitted limits. They are essential in conservation processes, storage, export and transport of sensitive products such as electronics, optical components, spare parts, precision machinery or chemicals.

At Conservatis we offer reliable, economical and easy-to-use humidity indicators, available in different formats and sensitivity levels to meet any environmental control need.

Available types of humidity indicators

Card-style humidity indicators (HIC)

Cards with reactive dots that change colour when a specific humidity level is exceeded. Ideal for sealed packaging, boxes with desiccants and barrier bags.

• 3-spot cards
• 6-spot cards
• Humidity levels from 5% to 95% RH
• Cobalt-free humidity indicators
• High-precision humidity indicator technology

Circular and adhesive-format indicators

Designed for small spaces or applications requiring a quick and compact reading. Suitable for small boxes, kits, technical cases or individual components.

• Individual circular indicators
• Adhesive versions for direct attachment

Complementary accessories for humidity control

Humidity indicators work effectively when combined with other conservation products.

• Aluminium barrier bags
• Silica Gel and activated clay desiccants
• Seals and conservation accessories
  
  

Benefits of humidity indicators

Humidity indicators provide a clear and quick verification of the internal environment in sealed packaging, facilitating audits, quality controls and logistics inspections. They help detect sealing failures, moisture presence during transport or product deterioration, reducing risks and claims.

As passive devices, they do not require energy, calibration or maintenance, making them a reliable and cost-effective solution for protecting sensitive products. Their use is essential in sectors such as electronics, military, optics, pharmaceuticals, automotive and industrial export.
