Sampling function: It has timing and quantity, fixed flow and quantity, timing ratio, and external control sampling mode, etc;

A/B dual bucket configuration: equipped with two mixing buckets, A and B, to collect instantaneous water samples and mixed water samples, mix and temporarily store water samples, and supply samples to COD, ammonia nitrogen, heavy metal and other instruments;

Excessive sample retention function: When the instrument measurement value exceeds the standard, it can be directly collected and retained as a sample, or configured throughA/B dual bucket implementation for mixed sample collection and retention of samples exceeding the standard;

Flexible sampling settings: When the instrument performs a single sampling, the sampling volume and number of sampling bottles can be freely set, providing greater flexibility;

Automatic emptying and rinsing: Before sampling, rinse the pipeline with the test solution, and after sampling, blow the pipeline back to ensure the authenticity and representativeness of the collected sample;

Water intake shortage alarm: When the system is unable to collect water samples normally, the instrument will sound an alarm and provide protection;

Anti overflow function: When the sample bottle is full, the instrument will sound an alarm and provide protection. The water sampling will be interrupted to prevent the water sample from overflowing;

Access control: Equipped with card swiping access control function and records of door opening and closing status;

Power outage protection: After the device is powered off, it can restore its working state before the power outage without losing data;

Reasonable layout: separation of water and electricity, separation of strong and weak electricity, ensuring safe and reliable equipment operation, and easy maintenance;

Reverse connection protection: Communication reverse connection protection ensures stable operation of equipment and is not affected by misoperation;

Refrigeration unit: including mixed samplingAB bucket, sample retention bottle，Capable of temperature control and low-temperature refrigeration of water samples.
