Tvoc Detector-EST-1000Pro-TVOC
The EST-1000Pro-TVOC series total volatile organic compounds detector is a portable instrument capable of measuring various toxic and harmful gases. It features an innovative and replaceable probe design, consisting of a main unit and a probe. Users only need to replace the probe corresponding to the type of gas to measure. It adopts high-precision circuit design, with the core using original imported sensor chips. After being developed and calibrated by Wanyi Technology, signal amplification, calibration and strict testing, it is released from the factory.
Product features
The sensor calibration cap can be connected to the gas sampling pump for use
2. It has a data storage function and can be connected to a computer to export tables
3. It is equipped with a two-level sound and light alarm function, and users can set the alarm value
4. There are over a hundred types of gas detection, and users can choose and select them by themselves
5. High-precision electrochemical sensors support submission for inspection to major metrology institutes
