PHG5203 second table one, T334 electrode a, pH (4, 7, 9) standard buffer a each one package.
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automatic alarm functions: alarm signal isolating output, alarm upper and lower limit can be arbitrary set, alarm lag withdrawn.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).
Standard fluid pH value automatically convert: stored the standard fluid temperature curve, calibration automatically converted into a standard set temperatures liquid in the pH.
Automatic discriminant error calibration: if users in the calibration wrong using standard buffer liquid, instrument will automatically tip.
