Ethylene concentration alarm instrument-Industrial-grade electrochemical sensor
The EST-10-Ⅱ-C2H4 ethylene detector is a portable handheld gas concentration measurement instrument. It adopts a natural diffusion gas detection method and has a data storage function. It can be connected to a sampling pump for use and is designed and produced in accordance with relevant national standards and alarm design standards. It adopts high-precision circuit design, with the core using original imported sensor chips. After secondary development, calibration, temperature compensation, signal amplification and stability testing by Wanyi Technology, it is completed. After the standard gas is mixed with a professional gas mixing instrument and the core sensor is calibrated, the product will only be released from the factory and delivered to the user after meeting the relevant national standards.
