Which is a good fully automatic integrator sampler

V-True 101AS Fully Automatic Integral Tank Sampler is a negative pressure sampler equipped with an inert, compact, and stable flow controller. It has ultra-high low flow stability and a wide range of flow rate applications, meeting the sampling flow requirements from 1 hour to 24 hours. It can be operated through a mobile app and instrument interface to directly set and calibrate the sampling flow rate, read the vacuum pressure inside the sampling tank, and perform timed sampling.

V-True 101AS Fully Automatic Integral Tank Sampler Performance Advantages:

1. Accurate flow control: error less than 0.2% of the full range; The flow controller can directly set the flow rate. Without the need to replace hardware, it is possible to set the flow rate for any time period from 1 hour to 24 hours, such as constant current sampling for 60 minutes, 120 minutes, and other time periods.

2. Diversified sampling modes: sequence programming sampling, event triggered sampling, remote start sampling, etc;

3. Integrated module control: integrating MFC flowmeter, pressure sensor, filter and timer, and software controls flow rate, digital display pressure, and sampling start stop;

4. Intelligent operating system: capable of remote operation, monitoring of various sampling statuses, and real-time recording and transmission of sampling records;

5. Integrated structural design: all pipelines and joints have no adsorption residue, and the sampling channel has no cross contamination;

6. Quality control function: equipped with functions such as Suma tank pressure detection, tank pressure judgment, flow calibration, and flow recording.

7. The instrument comes with a trend chart of the sampling flow rate and pressure inside the sampling tank over time, which is updated in real-time and can be downloaded through a mobile app or computer software.
