Description
Overview
GAOTek multi gas sensor – ≤ 20 seconds response time graphical display, and use the form of curve to reflect the trend of gas concentration changes in a certain period of time. 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).
