Tungsten trioxide from India for high-sensitivity sensors
Improvement in the performance of high-sensitivity sensors achieved by high-purity WO₃!
In the sensor industry, there is a demand for high sensitivity and stable performance. Particularly in sensors that capture minute signals, the purity and characteristics of the materials greatly influence performance. Tungsten trioxide, with its excellent thermal stability, chemical stability, and high melting point, contributes to the performance enhancement of high-sensitivity sensors due to its high purity. By using China-free raw materials sourced from India, we achieve both stable supply and quality reliability. 【Application Scenes】 - High-sensitivity gas sensors - Environmental monitoring sensors - Medical sensors 【Effects of Implementation】 - Improved detection limits due to increased sensitivity - Enhanced reliability through stable signal detection - Long-term maintenance of performance
