3R Series Three-Stage Temperature Stickers



The 3R series is a small, three-stage irreversible temperature sticker designed by NIGK specifically for precision indoor monitoring. The color-changing temperature starts with a number and progresses clockwise from low to high temperature. The sticker features an adhesive backing, is extremely small, and is weather-resistant, making it particularly suitable for application to PCBs, micro-component bearings, relays, or other confined spaces for localized hot spots. It provides a quick, on-the-go testing solution, helping maintenance personnel and engineers quickly determine if localized overheating or prolonged overload has occurred.
Product Introduction
The 3R series is a small, three-segment irreversible temperature sticker from NIGK, designed for use in confined spaces or with tiny components. The sticker features a three-point temperature display; as the temperature of the measured area sequentially rises to each threshold, the corresponding area of the sticker permanently changes color, irreversible, facilitating temperature history recording and anomaly warnings. This sticker is for indoor use only, complies with RoHS standards, and its extremely small size makes it suitable for temperature monitoring of high-space-density equipment such as miniature components, bearings, and circuit boards.
- Dimensions : 3-section temperature indicator, 1 mm diameter color-changing area (overall sticker diameter 6 mm)
- Packaging : 20 pieces/box
