Product features
1. Sulfur hexafluoride gas sensor is adopted, and 1000ppm SF6 standard gas is introduced for commissioning and calibration to ensure the measurement accuracy, which can be used immediately after startup;
2. Built in gas extraction pump and pump suction sampling mode, fast response;
3. External replaceable integrated dust filter;
4. External water vapor filter can be selected for occasions with high humidity;
5. Font color and background color can be set for different light intensity occasions to view the display interface;
6.The gas change curve can be viewed;
7. The storage capacity of 20000 records can be customized. It supports real-time storage, regular storage, local viewing and deletion of data. It can also upload data to the computer through USB and interface, and use the upper computer software to analyze, store and print data. Optional external micro wireless Bluetooth printer to print test results;
8.It adopts high-capacity rechargeable polymer battery and USB charging interface,;
9.Audible and visual alarm, fault alarm and other alarm functions. The alarm value can be set. The alarm mode can be low alarm, high alarm, interval alarm and weighted average alarm. The alarm status is displayed in a multi-directional and three-dimensional manner during alarm;
10.Two display modes can be switched: large font display of gas concentration and real-time curve of gas concentration change; You can set whether to display the maximum value, minimum value and gas name, and view the history curve;
