AB bucket water quality sampler online proportional automatic sampling of water quality exceeding the standard and retaining samples

Description :

　　1、 Product Overview

　　The online water quality automatic sampler adopts embedded control technology and is a fully functional intelligent sampler. Built in unique water sample temporary storage device can provide uninterrupted mixed water samples, which can be used in conjunction with online monitoring devices to achieve functions such as excessive sample retention, synchronous sample retention, and transportation of mixed samples; When used in conjunction with a flow meter, the sampling speed can be automatically adjusted according to the flow rate for flow tracking sampling, achieving continuity of sampling and making the measured water sample more representative.

　　The online water quality automatic sampler also has password protection, power-off protection and other protection functions, which can realize sampling in various ways such as timed, time proportional, flow proportional, flow tracking, external control sampling, serial port control, etc. It can also realize remote control of sample retention, remote parameter reading and setting, remote query of sample retention records and other functions.

　　2. Sampling function: It can achieve multiple sampling triggering methods such as timed sampling, time ratio, flow ratio, flow tracking, external control sampling, serial port control, etc.

　　3. Sample retention function: It can achieve functions such as excessive sample retention, synchronous sample retention, direct sample retention, and serial port control sample retention.

　　4. Sample supply function: It can provide uninterrupted mixed water samples to multiple online monitoring devices such as COD, ammonia nitrogen, heavy metals, etc.

　　5. Sample retention recording function: It can record the sample bottle number, retention time, retention amount, sampling mode, retention mode, retention frequency, parallel sample number, COD value, and NH3-N value for each retention, and can record 1000 data records.

　　6. Communication function (optional): Through the RS232 interface of the instrument, remote reset, remote sampling start, remote parameter modification, remote extraction of sample retention records can be achieved, and sample retention records can also be actively uploaded; We can customize communication protocols for users.

　　7. External interfaces: flowmeter simulation interface, RS232 interface.

　　8. Power off protection function: After the instrument is powered off and reconnected while in operation, it can automatically restore its original operating state, and the instrument parameters will not be lost after power off.

　　9. Automatic emptying function: After each sampling is completed, the system can automatically empty the water in the sampling pipeline to ensure that there is no sedimentation blockage in the sampling pipeline.

　　10. Moisturizing function: The sampling pipeline can be automatically wetted before each sampling to ensure the independence and representativeness of each collected sample.

　　11. Anti overflow function: Users can set the number of sample bottles to be retained, and stop retaining samples after completing the set number of bottles.

　　12. Water sample refrigeration function: Using an efficient refrigeration device, the retained water sample can be stored in an environment between 0 ℃ and 4 ℃.
