PH指示剂 91002 两种

UNISOL PH指示剂
主要特点：

◆液体试剂可直接用于液体样品或潮湿表面。

◆利用比色卡可直接读取1.0到13.0的PH值。
◆对于纯水，地表水，稀释后浓度很低的酸液和碱液以及弱缓冲溶液，如果使用试纸，由于会出现酸碱错误，所以只有在一定条件下才适用。

◆非缓冲溶液应选用液体指示剂：把液体指示剂加入待测水样，等变色后直接与色度尺比较即可。

◆应用于纯水和污水、水族馆水、非缓冲溶液、纸表面及类似产品等。

Liquid indicators

UNISOL are indicator solutions that are directly applied to the sample. The resulting colour of the sample is compared to a colour chart that is included in the kit. UNISOL indicator solutions are especially suitable for pH measurement in non-buffered samples like pure water or surface water. In these samples, other indicator papers find their limit of applicability.
UNISOL comes in units of 100 ml in drop bottle, with colour scale and 1 plastic cuvette MN 13/72
