FAQ3E Series Three-Stage Temperature Stickers
The 3E series is a three-stage irreversible temperature sticker launched by NIGK. It features three progressively changing color at different temperature points. Once one of these temperatures is reached, the color changes irreversibly, recording past temperature data and serving as a temperature warning indicator. The sticker requires no power supply or wiring, making it easy to operate and an ideal solution for temperature management in busbars, distribution panels, and mechanical equipment.
Product Introduction
This sticker is designed with a 3-stage temperature-sensitive color change (e.g., 50 → 60 → 70 ℃). As the measured temperature gradually increases, the sticker changes color sequentially according to the temperature threshold. This irreversible characteristic prevents later tampering, making it a highly reliable tool for recording high-temperature anomalies. The 3E series covers a variety of temperature models (from 40 ℃ to above 230 ℃) with 10 ℃ increments, meeting diverse temperature management needs.
In addition, the stickers comply with RoHS regulations, are 15 × 30 mm in size, and come in boxes of 20.
- Dimensions : 15 × 30 mm
- Packaging : 20 pieces/box
