II product overview

WS-AThe type of proportional mixed sampling exceedance retention device can achieve continuous collection and mixing of sewage at the discharge outlet, and provide the mixed sample for online analysis equipment to monitor the mixed sample of sewage at the discharge outlet. This solves the problem that traditional online monitoring monitors the sewage at the discharge point at equal time intervals, and the analysis cycle of water quality analysis instruments is often long. Therefore, the monitoring data obtained is only a set of sewage discharge data at equal time intervals, which cannot truly reflect the total amount of pollutant emissions at the discharge outlet. It can provide a powerful technical means for monitoring the total amount of sewage discharge and retaining samples beyond the standard.

This product is mainly used for enterprise sewage discharge outlets and is used in conjunction with existing sewage online monitoring systems.

III Characteristics of Sampler

Ø A/BDual bucket configuration: configurationA/BDouble bucket, capable of continuous mixed sample collection, instrument sample supply, and retention of samples exceeding the standard;

Ø host/Passive working mode: When the product is integrated into the analysis system, it can be used as the main control device to control the operation of equipment such as analyzers; Sampling tasks can also be executed based on the control instructions of the data acquisition instrument, making system integration very convenient;

Ø Sampler function: Mixed sampling can be performed at equal time intervals or equal flow intervals, with flexible settings for interval time, flow rate, and sampling volume;

Ø Water intake liquid level detection function: Before each mixed sampling, the system will judge the water intake liquid level and prompt and record a water free alarm;

Ø Multiple instrument sample supply modes: supports active sample supply (with pressure) and passive sample supply (without pressure) modes;

Ø Excessive sample retention function: When the instrument measurement value exceeds the standard, the system can achieve the function of caching the excessive sample retention of the water sample;

Ø Access control function (optional): To ensure the safety of equipment operation, the equipment has card swiping access control function, which can effectively prevent unauthorized personnel from interfering with equipment operation;

Ø Voice prompt function (optional): The device can provide voice prompts for important operations, such as the "empty sampling bottle" action;

Ø Add fixative function (optional): Supports automatic addition of fixatives such as sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide, etc;

Ø Multiple sampling modes: In addition to the mixed sampling over standard retention mode, the device also supports various conventional sampling modes such as ordinary over standard retention, timed quantitative, fixed flow quantitative, timed proportional, quantitative, etc., and can support remote control;

Ø The instrument has a high degree of intelligence and is equipped with real-time network communication interfacesRS232andRS485Accept information from the upper computer or designated control device to achieve remote sampling settings, execution, and response functions;

Ø The device has power-off protection function, and data is not lost;

Ø The sampling bottle box has a large volume and maintains a constant temperature throughout the year4±2Within the temperature range of ℃;

Ø When the instrument performs a single sampling, the sampling amount and number of sampling bottles can be freely set, providing higher flexibility;

Ø Sampling bottles can be selected24Capacity only1LReusable inert material sampling bottles, arranged in a circular box in a fan-shaped pattern, with a compact structure and large sampling volume;

Ø The sampling structure design is tight, the sampling and filling action is accurate and stable, the pipeline design is novel, and the back blowing design before and after sampling is adopted. The sampling pipeline has no residual sewage liquid, ensuring that the sample is pollution-free and authentic;

Ø Implement water and electricity separation, completely separate the control part from the mechanical water intake part, and improve the safety and stability of the instrument;

Ø Separation of strong and weak electrical components, more reasonable layout of electrical control components, large space, good heat dissipation, less impact on instrument transmission signals, easier maintenance, and high safety of strong electrical components;

Ø The excessive sample retention pump is placed inside the sampler, greatly reducing the vibration and noise during sampling, resulting in low noise and vibration during instrument sampling;
