Bench total phosphorus tester TZL-1

概述：  

 磷是水富营养化的关键元素。为了保护水质，控制危害，在水环境检测中总磷已经列入监测项目。

总磷包括水溶解的、悬浮的、有机磷的和无机磷，因此将未过滤的水样消解。消解就是将水中各形态磷转化成可溶态的无机磷酸盐的方法。消解的方法很多，用户按规程自行选择。总磷检测仪可以测量消解后的水溶液中无机磷酸盐的含量。

检测仪原理：  
本仪表应用微电脑光电子比色检测原理取代传统的目视比色法。消除了人为误差，因此测量分辨率大大提高。

Summary:

Phosphorus is a key element in water eutrophication. In order to protect water quality and control hazards, total phosphorus has been included in the monitoring project.

Total phosphorus consists of water dissolved, suspended, organophosphorus and inorganic phosphorous, and thus dissolves unfiltered water samples. Digestion is the process of transforming phosphorus into soluble inorganic phosphate in water. There are many ways to resolve the problem, and users can choose by themselves according to the procedures. Total phosphorus detector can measure the content of inorganic phosphate in dissolved water solution.

Principle of detector:

The instrument USES the principle of photoelectron colorimetry to replace the traditional visual colorimetry. The artificial error is eliminated, so the measurement resolution is greatly improved.

Technical indicators:

1. Measurement range: 0-1.5mg/L

2. Power supply voltage: 220V

3. Resolution: 0.01mg/L

4. Repeatability: 3%

5. Linear error: + / - (5% FS+
