Overview
Handheld gas detector | The detection type can be selected and different gas probes can be replaced. Shenzhen Wanyi Technology Co., Ltd. has been using the technology of American Environmental Sensor Technology Company for nearly 20 years to create the CESTSEN brand gas detector. The company focuses on the research and development, production, sales, and after-sales service of gas detection equipment. The core components of the equipment, sensors, are provided by outstanding sensor manufacturers in the United States, the United Kingdom, Germany, and other countries, and are carefully selected by the Wanyi Technology engineering team before being put into use. The complete set of gas distribution instruments is strictly calibrated in the laboratory. Handheld gas detector | Detection type can be selected and different gas probes can be replaced
Product Details
The EST-101A series high-precision gas detector is a portable handheld gas concentration measuring instrument with a replaceable probe design. It is divided into two parts: the main unit and the probe. Users only need to replace the corresponding probe to change the measuring gas. It adopts a high-precision circuit design and uses imported sensor chips as the core. After being developed and calibrated by Wanyi Technology, signal amplification, calibration, and strict testing, it is sent out of the factory.
The EST-101A multi probe gas detector mainly monitors gas types:
