More About This Item

The Traceable® 4192TR Humidity Card offers an easy-to-read visual indication of humidity conditions and is an effective tool for protecting moisture-sensitive materials. The card combines a reversible current humidity indicator with an irreversible maximum humidity memory indicator, allowing users to determine both present humidity conditions and the highest humidity level experienced over time.

The maximum humidity indicator records the highest relative humidity attained when exposed to elevated humidity levels for 24 hours or longer. The indicator changes from orange to yellow in 10% RH increments across the 50 to 90% RH range, providing a permanent visual record of peak humidity exposure.

The reversible current humidity indicator continuously responds to ambient conditions and changes color from blue to bright pink in 10% RH increments throughout the 0 to 100% RH range. This allows users to quickly evaluate current environmental conditions without requiring batteries, electronics, or specialized equipment.

Each humidity card is individually sealed in a clear moisture-barrier bag with desiccant to maintain indicator integrity and maximize shelf life until use. These cards are particularly useful for monitoring storage conditions of pharmaceuticals, laboratory chemicals, electronic components, optical equipment, packaging materials, and other humidity-sensitive products.

Every Traceable® humidity card includes an individually numbered Traceable® Certificate documenting traceability to SI units through NIST or other recognized National Measurement Institutes (NMIs). Calibration is performed by an A2LA-accredited ISO/IEC 17025 laboratory, supporting quality control programs, compliance initiatives, laboratory accreditation requirements, and audit documentation.

Guaranteed to have at least one year of calibration remaining on the certificate.
