水質自動采樣器
一：概述
在環境污染的監測和水體污染的調查工作中，要真實地反映水質污染狀況。必須采集具有代表性的水樣。特別是當前用立法和經濟手段搞好環境管理的情況下，在水資源保護工作中，如何采集具有代表性水樣的方法及其正確性，就是得更為重要。
可是，工廠排放的污水的水質、水量往往在短時間內有很大變化，生活污水也隨著人們生活習慣及季節變化而改變，所以總的水體和河流的污染情況是很復雜。而我們以往的取樣工具，一直是比較落后的手工操作。工作量大、準確性差。。
778型水質自動采樣器是專為排水工程中常用的四種量水堰配備的流量函數容器和電子儀器，達到采集有代表性的水樣。
本儀器可供工廠廢水排放口，河流固定水質監測點等處水質采樣使用，是一種*的取樣工具和計量工具。
二：儀器結構
水質自動采樣器、主要有以下組成：
（1） 采樣控制器：裝于室內，主要是設置采樣時間和采樣工作。
（2） 采樣電機：裝于室外水池
三：使用方法
（1） 將采樣電機的電源,插入到控制器后部（注意：采樣電機不可以全部浸入水中）,將配套的采樣管和采樣電機的出水口接好.
（2） 將采樣水管從采樣出水口接好、另一段接入實驗室的取水瓶中。
（3） 將采樣電機的電源線和室內的采樣器主機連好。
（4） 接上主機的電源，設定好采樣時間、就可工作。
（5） 采樣時間的設定步驟見下。
主要技術指標：
1、 電 源 電 壓：交流220V，式 頻 率：50HZ
3、每天采樣次數：20次
5、交流負載功率：阻性1000W
6、zui小編程間隔：1分鐘
7、采樣時間長短：0—99秒

Automatic water sampler
A: an overview
Research on the environmental monitoring and water pollution, to reflect the water pollution situation. Must be representative water sample. Especially in the current legislative and economic means to improve environmental management situations, in water resources protection work, how to collect representative samples and its correctness, is more important.
However, the water quality of the sewage, water from the factory often have great change in a short period of time, domestic sewage is also change with the living habits and seasonal people, so the pollution of total water and rivers are very complex. While our previous sampling tools, has been relatively backward manual operation. Heavy workload, poor accuracy..
Type 778 automatic water quality sampler is designed for drainage works in the four commonly used weir equipped with flow function container and electronic instruments, to collect the representative water samples.
The instrument can be used for wastewater plant, water quality of rivers water quality monitoring points fixed sampling, is a kind of advanced sampling tools and measuring tools.
Two: the structure of the instrument
Type 778 automatic water quality sampler, mainly has the following components:
(1) sampling controller: installed in the interior, is to set the sampling time and sampling.
(2) sampling motor: installed in the outdoor pool
Method of use: Three
(1) the sample motor power, inserted into the controller back (Note: sampling motor can not be fully immersed in water), will be supporting the sampling tube and a water outlet sampling motor connected
(2) the sampling pipe from the sampling outlet connected well, another access laboratory take the bottle.
(3) the sampling power line motor and indoor sampler mainframe connected.
(4) the power supply connected to the host, set the sampling time, it can work.
(5) the steps of sampling time.
The main technical indicators:
1, the electrical source voltage: AC 220V frequency, type: 50HZ
3, every sampling times: 20 times
5, the AC load power resistance: 1000W
6, the minimum programming interval: 1 minutes
7, sampling time: 0 - 99 seconds
