| 英文说明 | For measuring acidity and alkalinity (hydrogen ion concentration) based on a scale of 0 to 14 where 7 represents the value for pure water at 25oC or neutrality. Values less than 7 represent increasing hydrogen-ion concentration or increasing acidity, and a value greater than 7 represents decreasing hydrogen-ion concentration or increasing alkalinity. |
| 中文说明 | 该仪器用于测量酸碱度（氢离子浓度），以0到14的刻度表示，其中7表示25°C下纯水的中性值。数值低于7表示氢离子浓度增加，酸性增强；数值高于7则表示氢离子浓度降低，碱性增强。 |
