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automatic alarm functions: alarm signal isolating output, alarm upper and lower limit can be arbitrary set, alarm lag withdrawn.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.
Historical curve: continuous record of a month data, five minutes a point.
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.
1, which is two composite or distribution extremely three composites;
2 and electrode cable length, not according to match that was;
3 and electrode cable length more than 20m should match pHRT - 1, impedance transformer;
4, electrode and second instrument installation way.
5, power supplies, not to also signify AC220V match by.
6, measuring hydrofluoric acid or glass ball easily rupture with the solution T338 three composite pH antimony electrodes, an order to be indicated.
