Applied in industries such as water quality analysis, water treatment, pharmaceuticals, and chemical engineering.
Microcomputer-based: Adopts high-performance CPU chip, high-precision AD conversion technology, and SMT (Surface Mount Technology) to realize multi-parameter measurement, temperature compensation, automatic range switching, and instrument self-inspection, with high accuracy and good repeatability.
High Reliability: No complex function switches or adjustment knobs.
Strong Anti-interference Ability: Current output and alarm relays adopt photoelectric coupling isolation technology, ensuring strong anti-interference ability and enabling remote transmission.
Automatic Alarm Function: Isolated output of alarm signals; upper and lower alarm limits can be set arbitrarily, and alarm lag can be canceled.
Industrial Control Watchdog: Ensures the instrument will not crash.
Network Function: Isolated current output and RS485 communication interface; upper and lower limits of current corresponding to pH value output can be set arbitrarily, and hysteresis can be adjusted (adjustment range: 0～7.00pH).
Automatic Conversion of Standard Solution pH Value: Pre-stores the temperature curve of standard solutions; automatically converts the pH value of the standard solution at the set temperature during calibration.
Automatic Identification of Incorrect Calibration: If the user incorrectly uses standard buffer solution during calibration, the instrument will automatically prompt.
Electrode cable length: 5m as standard if not specified.
Electrode installation method.
Power supply: AC220V as standard if not specified.
Customization available for special requirements.
