phs-3d-01 lab ph meter
    simple desktop ph meter, which is suitable for general ph measurement in laboratory, consistent with the most simple requirements.

● large lcd with blue background can display both ph and temperature value at the same time.
● it has intelligent functions for automatic calibration, automatic temperature compensation, data storage / recall, and memory max. and min. value etc.
● 1~3 point automatic calibration, and it can automatically display the percentage of slope after finishing calibration
● there is manual and automatic tempearture compensation, which can be choose. it needs to equips a temperature electrode if user want automatic tempearture compensation.
● ℃ and ℉ can be switched freely.
