總硬度測定試劑盒
Water Hardness Test Kit
產(chǎn)品介紹：
水源中的硬度是指水中鈣鎂離子的含量，包括永久硬度和暫時硬度。不同的國家和行業(yè)表表達的單位是不同，在國內(nèi)一般可以表示為mg/L或mmol/L（以碳酸鈣計）。對于食品飲料行業(yè)，水體的硬度會很大程度上決定了產(chǎn)品的口感，所以在國標中對于食品飲料行業(yè)使用的水硬度有嚴格的要求。通常水中硬度的分析方法是EDTA滴定法，但是需現(xiàn)配一些試劑，不便于現(xiàn)場快速檢測，廣東環(huán)凱微生物科技有限公司開發(fā)的水質(zhì)硬度測試盒基于國標的EDTA滴定法，快速可靠，可以廣泛使用于涉水行業(yè)。
產(chǎn)品檢測范圍：4－200mg/L（以碳酸鈣計）LR
12-600mg/L（以碳酸鈣計）HR
當水樣的硬度低于20mg／L時，可以選用軟水硬度測試盒

Water Hardness Test Kit
Sources of hardness:
Water hardness originally refers to the precipitation of calcium and magnesium salt to soap. Different countries have different definitions to the hardness such as total hardness, carbonate hardness and non-carbonate hardness. Total hardness refers to the total concentration of calcium and magnesium. Carbonate hardness, which is equal to the hardness of calcium and magnesium combined with carbonate and bicarbonate in the water, is a part of the total hardness. Non-carbonate hardness is also a part of the total hardness. When the content of the calcium ion and magnesium ion in the water exceeds the content of carbonate and bicarbonate, the redundant ions will combine with the chloride ions, sulfate radicals and nitrate radicals in the water, then the non-carbonate hardness forms.
The significance of hardness test
The hardness of the water samples such as boiler water etc. is a very important index. Good controlling of the hardness can not only ensure the boiler safe in operation and improve the efficiency of the boiler, but also prolong the durable years of the boiler and save energy.
Principle
This method equals to the standard method that is EDTA-2Na Titration Method (GB5750-2006). The calcium ions and magnesium ions in water samples combine with EDTA-2Na successively to form chelate. On the end point of the titration, the solution presents the color of the indicator.
Quick and Easy
Operating in accordance with the instructions, users can complete the hardness test independently without specialized training. Five minutes is enough to complete the analysis of one water sample.
Accurate and Reliable
Determination results with this method are in accordance with the results with the standard method. It can be used as an alternative method to the standard method.
The range of the determination:
0.4～20mg/L(as CaCO3)
4-200mg/L(as CaCO3)
12-600mg/L(as CaCO3)
Quantitative Packing
The kit can be used for 50 times. It is small, light and easy to carry.
