The online pH meter is an instrument for measuring the acidity and alkalinity (pH) of a solution, by using a pH sensor to monitor and measure the hydrogen ion concentration in the solution in real-time. It has many unique features and functions and can be used in a wide range of applications in several fields. Besides, online pH meter has been simplified with guaranteed performance, resulting in a price advantage. It can be widely used in continuous monitoring of pH value in solutions of thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food, and tap water.
Micro-computerization: Adopting a high-performance CPU chip, high-precision AD conversion technology, and SMT patch technology, it can complete multi-parameter measurement, temperature compensation, automatic conversion of range, and self-test of the instrument, with high precision and good repeatability.
High reliability: no complicated function switch adjustment knob.
Strong anti-interference ability: current output and alarm relay adopt photoelectric coupling isolation technology, strong anti-interference ability, and realize remote transmission.
Automatic alarm function: alarm signal isolated output, alarm upper and lower limits can be set arbitrarily, alarm hysteresis withdrawal.
Network function: isolated current output and RS485 communication interface; the upper and lower limits of current corresponding to pH output can be set arbitrarily.
Automatic conversion of the pH value of the standard liquid: the temperature curve of the standard liquid is pre-stored, and the pH value of the standard liquid at the set temperature is automatically converted during calibration.
Automatic identification of incorrect calibration: If the user uses the standard buffer incorrectly during calibration, the instrument will be prompted automatically.
