Main features

Microcomputer: using high-performance the CPU chip, high-precision AD transform technology and SMT placement technology, perform multiple parameters measurement, temperature compensation, range automatically converts, instrument self-check and high precision, and repeatability.

High reliability: no complicated function switch and adjust knob.

Strong anti-interference ability: current output and alarm relay adopts photoelectric coupling isolation technology, strong anti-jamming capability, realize remote transmission.

The automatic alarm functions: alarm signal isolating output, alarm upper and lower limit can be arbitrary set, alarm lag withdrawn.

Industrial control type watchdog: ensure instrument won't crash

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).

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 installation way.

4, power supplies, not to also signify AC220V match by.

5, pHG5204 has discontinued, instead of model for pHG5203A.
