Online Industry pH ORP Controller pH Transmitter
>>Overview
The Industrial Online pH/ORP Meter is a microprocessor-based water
quality monitoring and control instrument. Configured with various
types of pH or ORP electrodes, it is widely used in power plants,
petrochemicals, metallurgy, electronics, mining, papermaking,
bio-fermentation engineering, pharmaceuticals, food and beverage,
environmental water treatment, aquaculture, modern agricultural
cultivation, and other industries. It provides continuous
monitoring and control of pH (acidity/alkalinity), ORP
(oxidation-reduction potential), and temperature values in aqueous
solutions.
>>Features
• Dot-matrix LCD display
• Smart menu operation
• Multiple automatic calibration functions
• Versatile signal output options, 4-20mA, RS485
• Data recording & curve display
• Differential signal measurement mode for stable and reliable performance
• Manual/automatic temperature compensation
• Relay control switches
• High/low limits with hysteresis control
• Simultaneous display of main Parameter, temperature, and status on the same interface
• Password protection to prevent unauthorized operation
