Product Category Description:

Unique humidity card indicates both the current and the maximum humidity attained. Easy-to-read cards are ideal for use with bottles, chemicals, plastic bags, electronics, desiccators, and storage containers. They monitor humidity levels in shipments, optics, and packaging.

Dual ranges are Current and Maximum Memory. Current range is 0 to 100% relative humidity. Color changes from blue to lavender in increments of 10% RH. Reversible indicator changes color as the humidity increases and decreases. Readable to an accuracy of ±5% RH at 24°C (75°F).

Maximum Memory range (the highest humidity attained when exposed for 24 hours or more) is 50 to 90% RH. Blue crystals dissolve in increments of 10% RH. Memory indicator is nonreversible. Readable to an accuracy of ±5% RH at 24°C (75°F).

Each card is individually sealed in a clear moisture-barrier bag with a Humidity Sponge™ desiccant to keep the card dry and provide for an extended shelf life. Card dimensions: 10.2x10.2cm (4x4").

A serial numbered certificate is provided from an ISO 17025 calibration laboratory accredited by A2LA to indicate instrument traceability to standards provided by the National Institute of Standards and Technology.
