Bsc Preferred DES160 Humidity Indicator Cards 125 Pack

Product Description

The BSC PREFERRED DES160 is a pack of 125 small paper humidity indicator cards designed to provide a simple visual alert when moisture levels rise in a protected space. Each card uses a color-reactive chemical that shifts from blue to pink as ambient humidity increases, giving technicians and handlers an immediate, no-tool read on whether sensitive equipment has been exposed to damaging moisture during storage or transit. These indicators are commonly used to protect electronic assemblies, optical instruments, and other moisture-sensitive components. The pack ships as a single case unit containing 125 individual cards.

These humidity indicator cards are suited for placement inside sealed packaging, equipment enclosures, shipping containers, and storage bins. They are particularly recommended when monitoring electronic equipment or optical instruments where moisture intrusion can cause corrosion, fogging, or component failure. The cards require no calibration and no power source, making them a passive, low-cost monitoring solution for warehouses, field service kits, and controlled-storage environments across HVAC, electrical, and electronics trades.
