What Is An Online PH Meter

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.

Main Features

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.
