Humidity Indicator HM-04-CDF
It allows quick and easy verification that the required humidity conditions have been maintained throughout storage and transportation. If the relative humidity inside the package reaches or exceeds a specified threshold, the corresponding indicator spot changes color from blue to lavender.
The HM-04-CDF Humidity Indicator is a single-use humidity indicator designed to monitor the relative humidity inside sealed packaging during the storage and transportation of moisture-sensitive products.
It provides a quick and easy visual verification that the required humidity conditions have been maintained throughout storage and transit. When the relative humidity inside the package reaches or exceeds a specified level, the corresponding indicator spot changes color from blue to lavender.
Thanks to its instant visual indication, the HM-04-CDF is an ideal solution for electronic components, semiconductors, optical devices, pharmaceutical products, and other moisture-sensitive materials.
Key Features of the HM-04-CDF Humidity Indicator
✅ Visual humidity indication – enables fast monitoring of relative humidity without the need for measuring instruments.
✅ Multiple humidity levels – monitors humidity at 10%, 20%, 30%, and 40% RH.
✅ Color-changing indication – the indicator spot changes from blue to lavender when the corresponding humidity level is reached or exceeded.
✅ Cobalt dichloride-free – environmentally friendly and safe design compliant with REACH requirements.
✅ IPC/JEDEC J-STD-033 compliant – suitable for use with Moisture Sensitive Devices (MSDs).
✅ Easy to use – simply place the indicator card inside a moisture barrier bag or transport package.
Applications
📌 Electronic components and semiconductors
📌 Printed circuit boards (PCBs) and SMD components
📌 Optical and measuring instruments
📌 Medical and laboratory equipment
📌 Pharmaceutical products
📌 Moisture-sensitive industrial components
Reading the Humidity Indicator
📌 Blue – Relative humidity is below the indicated value.
📌 Lavender – Relative humidity has reached or exceeded the indicated value.
For example, if the 10% and 20% indicator spots are lavender while the 30% spot remains blue, the relative humidity inside the package is between 20% and 30% RH.
Recommended Use
For maximum product protection, we recommend using the humidity indicator together with:
📌 Aluminum foil barrier bags (Moisture Barrier Bags – MBBs)
📌 Desiccant bags
📌 VCI corrosion protection packaging
This combination provides reliable protection against moisture during both storage and transportation.

Plastic Security Seals
Plastic security seals are single-use security closures designed to protect shipments, shipping containers, and storage units from unauthorized tampering. Once sealed, they cannot be opened without causing visible damage, so any attempt to open them is immediately apparent. Each seal is marked with a unique serial number, which allows for easy identification, tracking, and verification during both transit and storage.
