SEM-803AAutomatic water quality sampler (online connected model)
Application Overview
Automatic water quality sampler (online connected model),This water quality automatic sampler is widely used in pollution sources, sewage treatment plants, andCODOnline monitoring devices for ammonia nitrogen, heavy metals, etc. are used online. In addition to traditional timing, time ratio, and flow ratio sampling modes, it also has functions such as synchronous sampling, excess sample retention, and remote control sampling.
When abnormal data occurs in the monitoring device, backup samples will be automatically retained for cause analysis and environmental law enforcement purposes, aiming to solve the problem of lack of traceable data. Various controls of the sampler can be achieved through a remote monitoring platform. This product is an effective supplement to online monitoring devices and has been widely installed at the total discharge outlet.
The water quality sampler is a multifunctional intelligent environmental monitoring instrument that integrates flow measurement, water sample collection, and automatic packaging. The Juchuang instrument has the characteristics of small size, easy mobility, simple operation, environmental protection and energy saving. Juchuang is suitable for environmental monitoring stations, supervisory agencies, research institutes, water affairs, municipal and sewage treatment plants at all levels, to automatically sample water samples from industrial pollution source discharge outlets, rivers, lakes, seas and other sources.
Functional Features
1)Conventional sampling: timed, time proportional, flow proportional, liquid level proportional, external control sampling;
2)Bottle division method: parallel sampling, single sampling, mixed sampling and other bottle division methods;
3)Synchronous sample retention: synchronized sampling and retention with online monitoring devices, commonly used for data comparison;
4)Excessive sample retention: used in conjunction with online monitoring instruments,Automatically retain water samples in sampling bottles when monitoring data is abnormal;
5)Remote control(Optional)Can achieve remote status query, parameter setting, record uploading, remote sampling, etc;
6)Power outage protection: automatic power outage protection, automatic power on restoration work;
7)Records: with sampling records, door opening and closing records, and power outage records;
8)External pump control: directly control the external pump to extend the sampling distance;
9)Automatic rinsing: Before each sampling, rinse the pipeline with the water sample to be tested to ensure the representativeness of the retained sample;
10)Automatic emptying: After each sampling is completed, the pipeline is automatically emptied and the sampling head is blown back;
11)Digital temperature control: precise digital temperature control for refrigerated containers, equipped with a uniform heating system, ensuring even and accurate temperature distribution.
