1. digital LCD display, english operation system.
2. Have function of temperature compensation automatically or by hand.
Self-calibration, self calibration of electrode percentage
3. Five buffer liquid could be choosed to automatically calibration
( 1 or 2 point )
4. Testing record could be stored, deleted, read, printed, maximum
could store 200 items.
5. Have RS-232 connection point. Could connect TP-16 printer,
also could connect data collection system or computer.
6. Could test ultra pure water PH value, Pure water PH water or
boiler PH figure when using specific electrode.
7. Use combined electrode and temperature electrode
