Description:

EJ-HC01B type (insulated mixed 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, using refrigerator insulation, has a sample container to store the water. It can collect samples by the specific timing and quantitative.

The main technical parameters:

1.Sampling Method:

* Equal-time or unequal-time mixed water samples: (time control sampling)

* Sampling interval: (1 ~ 9999 minutes) can be set arbitrary

* Equal proportion mixed water sample: (flow control sampling)

* Connected with special flow sensor to control sampling: 1～9999M3, can be set arbitrary

* Flow meter control sampling with output pulse: (The output pulse should be 5V ~ 15V positive pulse). 1 to 9999 pulses arbitrary. (The flow rate represented by each pulse is set on the flowmeter).

2. Number of mixed water samples (N) : 1 to 200, can be set arbitrary

3. Vertical sampling height: 8m.

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

5. Sample volume error:. ± 8%

6. Sampling repeat accuracy: ± 5ml.

7. Storage container: 5-10 liters polyethylene bottle.

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.

16. The instrument is equipped with RS232 interface, which can control sampling externally, and output the time and flow  parameters of the sampled product.

17. Working environment temperature: -5°C to +50 °C.

18. Water sample storage temperature: 0～8℃ adjustable, temperature control error: ±2℃
