Description:

EJ-FC24B type (separate collection type) automatic water sampler is an environmental monitoring instrument designed by our company, which is used for online automatic sampling of the pollution sources. It uses a special peristaltic pump for sewage to take water, with a large pipe diameter and fast flow rate, which can effectively avoid pipeline blockage. Under the control of a 32-bit high-performance industrial-grade ARM controller, the sampling method, sampling time interval, sampling amount and storage location can be arbitrarily set according to user’s needs. It can be sampled simultaneously with on-line monitoring instruments (such as on-line COD, ammonia nitrogen, total phosphorus and total nitrogen, heavy metals, etc.). It is used for comparison experiments with the test results of online monitoring instruments. After connecting to the flow sensor (optional), the dual work of sewage metering and sampling according to the flow rate can be realized. The online monitoring instrument can realize over-standard retention sample. It can also realize remote wireless control, and randomly issue sampling instructions as needed. So as to obtain a real and effective water sample. It is one of the necessary instruments for environmental monitoring departments to improve work efficiency, reduce labor burden, and ensure the accuracy and effectiveness of monitoring data.
Features:

Fixed automatic water sampler has a refrigerator insulation, that the samples can be stored at constant temperature. There are 24 sample storage containers which can collect samples with equal proportion by the specific timing and quantitative sampling.

The main technical parameters:

1.Sampling Method:

* Standard sampling:

Sampling delay time: (1 ~ 9999 minutes) can be set at one minute increments

Sampling interval: (1 ~ 9999 minutes) can be set at one minute increments.

Sample volume: 50 ~ 1000ml arbitrary increments 1 ml

Mixed sampling:

Sample delay time: (1 ~ 9999 minutes) set arbitrarily, one minute increments

Sampling interval: (1 ~ 9999 minutes) can be set at one minute increments.

Sample volume: 50 ~ 1000ml arbitrary increments 1 ml

Mixed number of samples: (1 to 20)

Parallel sampling:

Sampling delay time: (1 ~ 9999 minutes) can be set at one minute increments

Sampling interval: (1 ~ 9999 minutes) can be set at one minute increments.

Sample volume: 50 ~ 1000ml arbitrary increments 1 ml

Number of samples in parallel: (1 to 24)

* Flowmeter control sampling:

Connected with special flowmeter control samples. 1 to 9999 pulses arbitrary. increment one pulse. The output pulse should be 5V ~

15V positive pulse.

* Output pulse flowmeter control samples :

1 to 9999 pulses arbitrary, increment one pulse. The output pulse should be 5V ~ 15V positive pulse.

3. Sample volume error:. ± 8%

4. Sampling repeat accuracy: ± 5ml.

5. Vertical sampling height: 8m.

6. Horizontal sampling distance: 50 meters. With a sampling tube automatic flushing function

7. Storage container: 24 1000ml polyethylene storage bottles.

8. System clock time control error: :△1 ≤ 0.1% and △24 ≤ 30S.

9. Air tightness of piping system: ≤-0.05MPa.

10. MTBF (Mean Time Between Failures): ≥ 1440h.

11. Insulation resistance:> 20MΩ.

12. 2.8TFT true color touch screen.

13. Software password lock that protects the instrument setup program will not be modified.

14. Can be preset and store 10 common procedures in accordance with the sampling requirements, could later be used directly.

15. The instrument can automatically record and store each sampling situation. After the flowmeter is connected, the flow data of three months can be recorded at five-minute intervals. Each set of data includes: month, day, hour, minute; instantaneous flow; cumulative flow. The recording time interval of each set of flow data can be set arbitrary. The larger the interval, the longer the recording time, and the cyclic update method is adopted. The stored data will not be lost after power failure, so you can check it at any time. Users can perform data analysis based on these data and the test results of the water samples.
