DR-803F2 water quality automatic sampler (bottom self discharge

　　Application Overview

This water quality automatic sampler is a new generation intelligent water quality automatic sampler developed by our company. The sampler can automatically sample in multiple modes, including timed sampling, time proportional sampling, flow proportional sampling, and excess sample retention; In the case of long-term unattended sampling, expired water samples can be automatically emptied for the next sampling, achieving the goal of the sampler being able to cycle. Suitable for environmental protection departments, sewage treatment plants, drainage management offices, and sewage discharge enterprises to automatically collect, refrigerate, and drain water samples from surface water, water treatment processes, and enterprise total discharge outlets.

　　Features

Sampling mode by bottle: The instrument can achieve 1-25 bottle sampling by bottle, and the number of bottles can be freely set;

Multiple sampling modes: timed, time proportional, flow proportional, flow tracking, and retention of samples exceeding the standard;

Automatic emptying function: The instrument can automatically empty the water sample. When there is no sampling for a long time, the instrument can automatically empty the water sample in the sampling bottle for the next sampling, ensuring that the instrument is in working operation;

Sampling record function: It can record information such as sampling time, sampling volume, sampling bottle number, sampling mode, etc. for each sampling, and can store 1000 sampling records;

Operation record: It can record the opening time of the water sample refrigerator door and the change time of important parameters each time;

Communication function: It can communicate with other instruments through RS-232/RS-485;

External interface: capable of connecting flow meter signals and liquid level meter signals at 4mA to 20mA;

External pump control function: When the sampling distance is greater than the distance range of the built-in sampling pump, the external sampling pump can be used for relay sampling;

Power outage protection function: After a sudden power outage, the instrument can automatically restore its original operating state when powered on again, and the instrument parameters will not be lost after the power outage;

Sample constant temperature storage function: Under the control of the temperature control system, the sample can be stored at a constant temperature of 4 ℃± 2 ℃.
