20, can match three composite or two composite electrode.
Electrode installation: circulation type/sink into type/flange/pipeline/lateral wall type
Standard configuration: pHG5203B second table one, T334 electrode a, pH (4, 7, 9) standard buffer a each one package.
Chinese LCD display, Chinese menu type operation.
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.
Waterproof dustproof design: protection class IP65.
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
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automatic alarm functions: alarm signal isolating output, alarm upper and lower limit can be arbitrary set, alarm lag withdrawn.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.
Manual current source: convenient records and detection device testing.
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 add junction box; More than 50m please select pHG5201 matchs the preamplifier;
4, electrode installation way;
5, power supplies, not to also signify AC220V match by.
