Chinese LCD display, Chinese menu type operation, the Chinese history
Microcomputer: using high-performance the CPU chip, high-precision AD transform technology and SMT placement technology, perform multiple parameters measurement, temperature compensation, instrument self-check and high precision, and repeatability.
High reliability: veneer structure, touch buttons, no switch knob and potentiometer.
Waterproof dustproof design: protection class IP65, suitable for outdoor use.
The electromagnetic compatibility (EMC/RFI) design: by European standards 50082 EN50081 / design and manufacture.
25 ℃ convert: can realize the sandhust electrode slope temperature compensation, pure water and add 25 ℃ convert ammonia ultra-pure water
Stances impedance input circuit: low impedance PH electrode, the instrument of fast response, good stability, strong anti-jamming.
Solution: eliminating linked to loop interference.
Electrode diagnosis: various calibration way, E0, S query, monitoring electrode properties.
The automatic alarm functions: alarm signal isolating output, alarm upper and lower limit can be arbitrary set, alarm lag withdrawn.
Network function: the isolation of current output and RS485 communication interface; Current corresponding pH value of the upper and lower limit output can be arbitrary set; Hysteresis quantity can adjust, the adjusting range (0 ~ 7.00 pH).
Industrial control type watchdog: ensure instrument won't crash.
Notepad function: record 200 information.
Manual current source: convenient records and detection device testing.
Built-in real time clock: provide various function of time benchmark, etc.
Password management: calibration, parameter setting and maintaining all have password protection
