Automatic Sampling and Analysis System for Soil Pore Gap

1.The soil pore gap automatic sampling analyzer is an integrated design, and the sampling flow rate can be automatically adapted. It can automatically start and stop the pump according to the well conditions

Adjust the exhaust flow rate; Real time display of sampling flow rate and pressure, real-time displayVOCTheCO2TheO2TheCH4TheH2SDetecting data,

2.Extract two pipelines, one with a flow rate of100～500ml/minAccurate adjustment within the scope; Another one is500~2000ml/min

Accurate adjustment within the scope;

3.The entire pipeline connection material is made of inert materials(For example, PTFE pipes and stainless steel parts);

4.The air inlet is equipped with a drying device for easy replacement, and the replacement frequency should not be less than12Hourly working conditions required;

5.Range of flow display instrument0~3000ml/min,Real time display of exhaust flow rate;

6.The size of the soil pore gap automatic sampling analyzer shall not exceed30*15*22cm,Can walk with one hand;

7.The instrument is equipped with an integrated lithium-ion battery, which can work continuously for a minimum of24Hour;

8.VOC:Range:0-20PPM,zuiSmall exploration measurement1.5ppb,Detection principle: photoionization;

9.hydrogen sulfide:0-10 ppm,Accuracy:<2%,resolution<0.01 ppm;Measurement principle: electrochemistry.

10.Oxygen: Range0-35%VOL,resolution0.1%,Accuracy ±0.5%,Measurement principle: electrochemistry;

11.Methane: Range:0-5VOL%,Accuracy: ±5%FS,Resolution:0.01 VOL %;

Detection principle: Non dispersive infrared(NDIR)Testing technology;

12.Carbon dioxide: Range:0-1000 ppm,Accuracy: ±3%FS,Resolution:1 ppm;

Detection principle: Non dispersive infrared(NDIR)Testing technology;

13. You can set the comparison interval time and stable range by yourself; Automatically compare data to determine if the well flushing has ended,

After stabilization, send a prompt message and record the reading;
