Description
Overview
GAOTek Combustible Gas Detector has graphical display and uses the form of curve to reflect the trend of gas concentration changes in a certain period. Data recovery function; in case of mis-operation, it is possible to select partial or full recovery. It is possible to set whether to display the maximum value, minimum value, average value or not. Standard USB charging port, with charging protection function, USB hot plug supported, and the charging status instrument can work properly. 4600 mA high-capacity rechargeable polymer battery is adopted, so it is possible to work for a long period of time. High-precision temperature and humidity measurements (optional configuration).
Features
- Adopted advanced electric circuit design.
- Mature kernel algorithm processing.
- Unique external appearance design.
- Had achieved a few patents about the software works
- Possible to simultaneously detect 1 to 6 types of gases
