PHG5203B online Chinese PH dollars

PHG5203B is my company a new generation of all Chinese microcomputer type, with all Chinese high-grade instrument display, Chinese menu type operation, all the intelligence, multi-function, measurement, high performance environment adaptable wait for a characteristic, can accurate measurement of the solution pH value and temperature. Can be widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmacy, biochemical, food and water and other solution pH value of continuous monitoring.

Technical indicators

1, standard: JB/T 6203-92 "industrial pH dollars";

2, displays with the Chinese menu, a chinese-language interface.

Three, measurement range: pH value 0 ~ 14.00 pH, dividing value 0.01 pH;

0 ~ 99.9 ℃ temperature degrees 0.1 ℃, dividing value;

Potential value - 1999 ~ + 1999mV, dividing value 0.1 mV;

4, precision: pH: + 0.05 pH; Temperature: + 0.5 ℃ (0 ~ 60.0 ℃);

5, automatic temperature compensation range: 0 ~ 120.0 ℃, 25 ℃ for benchmark;

6, be measured 120.0 ℃ water: 0 ~ 0.6 MPa,;

7, electronic unit automatic temperature compensation error: + 0.03 pH;

8, electronic unit repeatability error: + 0.02 pH;

9, stability: + 0.02 pH / 24h;

10, input impedance: p 1012 Ω;

11, current isolation output: 4 ~ 20 mA; Can choose two road, on the output current temperature, all pH or two road pH, please order specified, all output current standard disposition.

12, output current error: acuities + 1% FS;

13, discretion alarm relay: AC220V, 7A;

14 and RS485 communication interface (optional), also optional RS232 communication, please specify ordering;

15, power: AC220V + 22V, 50Hz + 1Hz; Optional DC24V, please order specified when.

16, protective level: IP65;

18, weight: 0.8 kg;

19, working conditions: environmental temperature 0 ~ 60 ℃ relative humidity < 85%;

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.

Main features

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.

Purchasing guidelines

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.
