SemeaTech has released a new product, the 4AsH3-1 & the 4AsH3-10 sensor, for applications in gas monitoring in environments where AsH3 (hydrogen arsenide) may be present, such as semiconductor production. The AsH3 sensor can also be used for gas monitoring in metal smelting, processing, storage, and other chemical environments. Based on our proprietary electrochemical technology, the 4AsH3 sensor has excellent linearity, repeatability, environmental dependency, and long-term stability.
