Moisture Indicator – Transparent

The transparent humidity indicator allows for quick and easy monitoring of relative humidity inside sealed packages without having to open them. If the relative humidity reaches or exceeds a specified value, the corresponding indicator field changes color from blue to pink.

Full product description and features

The transparent humidity indicator is used to monitor relative humidity inside sealed barrier packaging during the storage and transport of moisture-sensitive products.

The indicator is installed directly into the wall of the protective packaging and allows monitoring of internal conditions without disrupting the protective environment. When the specified relative humidity level is reached, the corresponding indicator field changes from blue to pink.

Thanks to immediate visual assessment, it is an ideal solution for industrial products, electronic components, machinery, and other materials requiring protection from moisture.

🔹 Key Features of the Transparent Moisture Indicator

✅ Visual Moisture Monitoring – allows you to monitor relative humidity without opening the protective packaging.

✅ Multiple indication levels – available in 3-point (30%, 40%, 50% RH) or 5-point (40%, 50%, 60%, 70%, 80% RH) versions.

✅ Color change – when the corresponding humidity level is reached, the indicator field changes from blue to pink.

✅ Inspection without damaging the packaging – allows you to verify conditions inside the package without compromising the protective environment.

✅ Manufactured according to MIL-I-8835 – the indicator is manufactured in accordance with this standard.

✅ Easy to use – installed in the wall of barrier packaging in combination with desiccant pouches.

🔹 Areas of Application

📌 Engineering products and metal components

📌 Electronic components and sensitive equipment

📌 Optical and measuring instruments

📌 Industrial machinery and spare parts

📌 Overseas and long-distance transport

📌 Long-term storage in ALU barrier packaging

🔹 Indicator evaluation

📌 Blue color – relative humidity is lower than the specified value.

📌 Pink color – relative humidity has reached or exceeded the specified level.

For example, if the 30% section of a three-point indicator is pink and the 40% and 50% sections remain blue, the relative humidity is approximately between 30% and 40% RH.

🔹 Recommended Use

For maximum product protection, we recommend using the transparent moisture indicator in combination with:

📌 ALU barrier packaging

📌 Desiccant bags

📌 Anti-corrosion packaging

This combination helps protect products from moisture while allowing you to control the conditions inside the sealed packaging during storage and transport.
