Indicator tapes are specialized tapes that provide a visual indication when a specific condition has been met. They are designed to change color, texture, or appearance when exposed to a particular substance, temperature, or other environmental factor.

Indicator tapes come in a wide variety of types, each designed to detect a specific condition. Common types include moisture indicator tapes, temperature indicator tapes, pH indicator tapes, and tamper-evident indicator tapes.

Indicator tapes have numerous applications across various industries. They are commonly used in packaging, manufacturing, healthcare, and scientific research to monitor conditions such as moisture levels, temperature changes, product tampering, and chemical exposure.

Using indicator tapes is generally straightforward. The tape is applied to the surface or object being monitored. When the specific condition is met, the tape will change its appearance, providing a clear visual indication. The interpretation of the color change or other visual cue will vary depending on the type of indicator tape being used.
