Product description

EJ-FC24A type (portable separate collection type) automatic water sampler is a dedicated environmental monitoring instrument used for surface water and wastewater sampling, the monitoring of water sources, and investigation of the pollution source. The water intake method is pollution-free and controlled by a built-in computer program (optional remote control machine). After users setting the sampling time, timing, quantification and sampling method, it can automatically complete the work online. After connecting flow sensor (with optional) can realize sewage metering and sampling according to the flow rate. This instrument is a portable water sampler with separate bottles, equipped with imported high-quality drive and built-in 12V lithium battery power supply. It is applicable to environmental monitoring stations at all levels, universities, and research institutes to automatically take water samples after determining sampling points for surface water or pollution sources in rivers, lakes, and seas.

Features

The rechargeable portable automatic water sampler is convenient to carry to the field for sampling. It has 24 sample containers, which can store samples in separately. And sample storage at constant temperature.

The main technical parameters:

1.Sampling Method:
* Standard sampling:
Sample volume: 50 ~ 1000ml arbitrary
Mixed sampling:
Sample volume: 50 ~ 1000ml arbitrary
Mixed number of samples: (1 to 20)
Parallel sampling:
Sample volume: 50 ~ 1000ml arbitrary
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.
2. Peristaltic pump flow characteristics:. 3.4L/min (when suction range is 3m); 2.2/min (when suction range is 6m)
3. Sample volume error:. ± 5%
4. Sampling repeat accuracy: ± 4ml.
5. Vertical sampling height: 8.5 m.
6. Horizontal sampling distance: 50 meters. With a sampling tube automatic flushing, regular sampling, quantitative sampling, automatic emptying, steering switch and other functions
7. Storage container: 24 1000ml polyethylene storage bottles. Sample storage at constant temperature.
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. The software intelligently controls the sampling method and sampling volume, sets the length of the sampler water pipe. It can automatically calculates the flow range according to the length of the sampling pipe, and automatically records the number of times the instrument is used.

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

14. The system adopts integrated precision circuit structure, ARM system control, composed of control circuit and drive circuit, built-in communication protocol, can be used with flowmeter and external control terminal to achieve the effect of external terminal control sampling; The system is equipped with internal storage, which can store sampling backup data, and can be used for common sampling module settings. With a micro-USB interface, the settings can be verified on the computer.

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. Sampling pump parameters: YJ/T161mm*106mm*40mm. The inner diameter of the pump tube is 10mm, with filtering and backflushing function. It can be removed freely and easy to replace.

17. Driver parameters: YJ/T 45mm*65mm, DC-12V RPM: 263+10%, with drive precision control circuit system, to achieve perfect integration with system software, can control the sampling precisely. It also has the precision sealed bearing structure and copper wire motor.

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

19. Power supply:. AC220V/50HZ ± 10%; DC12V; Power: 60W. Dedicated power bank can be added.
