Through systematic calibration and maintenance, the metal shell static wrist strap alarm can be ensured to maintain high sensitivity throughout its entire lifespan.

While brushing removes most of the surface plaque in daily oral care, it often misses the "blind spots" between teeth.

The thermal stability of PC plastic is not only reflected in its wide operating temperature window and excellent high-temperature mechanical properties, but also in its ability, through material modification and engineering design, to readily address dive

To effectively control this "invisible killer," a metal shell static wrist strap alarm... The alarm was developed to address this need. It's not just a monitoring device, but a "metal shield" integrating precise sensing, reliable alarm, and robust protect

In modern oral care, removing plaque between teeth—where a toothbrush can't reach—has become a key step in preventing caries and periodontal disease.

When the resistance exceeds the preset safety range, the system determines it as a grounding anomaly and triggers an alarm.
