Release of 4AsH3-1 Gas Sensor

Update time:2022-07-15 13:32
SemeaTech has released a new product, the 4AsH3-1 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 4AsH3-1 sensor has excellent linearity, repeatability, environmental dependency, and long-term stability.


All SemeaTech electrochemical gas sensors can be paired with the Smart Modules to have digital output, such as I2C and UART. If you need any samples, please email us at
