DR-803M4 water quality automatic sampler (shore station self

　　Application Overview

This water quality automatic sampler is suitable for shore based water quality automatic monitoring stations. The sampler can be integrated with the surface water quality automatic monitoring system to achieve timed sampling, time proportional sampling, synchronous sampling, external control sampling, over limit sampling, and immediate sampling functions. The sampling bottle has sealing function, automatic emptying function, and automatic rinsing function, and can be recycled.

The water quality automatic sampler also has protection functions such as password protection and power-off protection, as well as features such as small size, automatic refrigeration, and easy installation. It is an important component of the shore based water quality automatic monitoring station.

　　Features

There are various sampling methods: timed sampling, time proportional sampling, synchronous sampling, external control sampling, over limit sampling, immediate sampling, and other functions;

Bottle splitting method: single sampling;

Automatic rinsing: Use the original water sample to automatically rinse the pipeline and sampling bottle before sampling;

Automatic emptying: Automatic emptying of sampling bottles and pipelines;

Low temperature refrigeration: electronic temperature control, water sample storage temperature 4 ℃± 2 ℃;

Electronic access control: Open the electronic lock after password verification is passed;

Communication: It can remotely read and set working parameters through serial port;

Power off protection function: After the instrument is powered off and reconnected while in operation, it can automatically return to the operating state before the power outage, and the instrument parameters will not be lost after the power outage;

Sampling record function: It can record information such as the time, amount, and mode of each sampling, and can store 1000 sampling records;

Power outage record: It can record the time of each power outage and power on of the sampler, and can store 1000 power outage records;

Access control record: It can record the time of each opening of the access control for the water sample refrigeration room, and can store 1000 access control records;

Alarm record: When sampling fails, an alarm message can be generated and 1000 alarm records can be stored.
