PHS-3CT Automatic PH Meter
Instruction
Ⅰ. General
The PH meter is a kind of acidometer with automatic or manual temperature compensation, automatic or manual calibration of gradient of electrode and LED digital display. It is applicable to research institute, factory, hospital and mine, etc and used to test temperature, PH value, potential of electrode（mV）. If equipped with appropriate electrode selected according to ion, it can also be used to analyze variation of potential in determination of potential.
Ⅱ. Main Characteristics of Instrument
1. Microprocessor technology is adopted.
2 Calibration of PH value, temperature and mV.
3 Automatic or manual temperature compensation.
4 Temperature displayed both in PH and mV
5 Referential parameters are calculated by software without adjustable component.
6 Parameters can be saved automatically and doesn’t lose without electrifying.
7 Gradient of electrode and deviation can be displayed automatically.
8 Equipped with E-301type 3-composite PH electrode（with pt1000 temperature transducer）or E-201 type composite electrode and pt1000 temperature transducer.
9 100 PH data can be saved and read.
10 Communicate with computer by serial interface of RS232, read saved PH value and can transmit current results of measurement.
