PH试剂使用说明
The Operating Instruction of the PH Reagent
本试剂的特点:
1、颜色鲜明,易于通过颜色变化来区分酸碱性;
2、便于携带,10ml的量使用更经济、方便;
3、适合于做体验式营销的好伴侣。
【用法用量】
【Usage and Amount of Usage】
1.将本试剂滴3-4滴于50ml被测溶液(无色)中,摇匀,根据被测溶液的颜色变化,对照色别表,即可读得相应所测溶液的数值。
2.PH试剂也适用于非常弱的缓冲溶液和浓度低于0.01%PH=4~10之间的酸碱溶液.即在试纸无法测定下,本试剂效果显著.
1. Drip 3~4 drops of the PH regent into the solution (colorless) of 50ml that to be measured, shake for even, check for the color change, and corresponding to the PH color table, read the PH test result of the measured solution.
2. This PH regent is also applicable to the very weak buffer solution or to the weak acid and weak alkali solution with the concentration lower than 0.01% or 4~10 PH. Even for the circumstances when PH papers can not be in function, this PH regent can still give a significant test result
【贮藏】避光,密闭在室温阴凉处.
【Storage】Keep from the light, sealed in the cool places of room temperature.
【注意事项】
1. 禁止饮用;
2. 远离烟火;

PH测试剂
PH测试剂使用方法:先用需要测定的水清洗试管1—2次,然后加入实测水质10毫升,滴入PH酸碱测试液两滴,搅拌3-5秒,显色后与标准色卡进行对比(30秒以内进行色卡对比),可测得该水质的PH值。
常识:自来水一般都是在7.0左右,但自来水的PH值是动态变化,与自来水厂的处理工艺、加药的浓度有关,所以不同时间段测试自来水的PH值有可能会出现不同的PH值,属于正常现象。
