PHD-99S Intelligent pH/ ORP Transmitter
Instruction
PHD-99S transmitter is an intelligent microprocessor industry online detecting instrument. It has flame-proof structure, advanced function and high performance priceratio which can be used in sewage treatment,
wastewater monitoring, water detection, acid-base neutralization, chemical reaction and the monitoring
and control of pH/ORP value in various industrial process.
Instrument Features
Intelligent instrument, check the performance parameters of the electrode through menu calibration and parameter setting.
Blue backlight LCD displays pH (mV), temperature, output percentage simultaneously.
24VDC two-wire
Output 4-20mA
Corresponding range can be set arbitrarily.
Manual or automatic temperature compensation, PT100, PT1000 temperature sensor can be switched by setting.
Calibration and parameter adjustment can be operated by key or by magnetic rod outside the shell in flame-proof occasions.
