PH Analyzer


Overview

SMART series intelligent multi-parameter universal controller has high accuracy, its unique professional design can be applied in water, chemical, pharmaceutical, food and hygiene in the production process of the most extreme physical and chemical environments. SMART series intelligent multi-parameter universal controller has modular bus structure, highly scalable functionality, high reliability and comfortable operation.


Principle

PH is the negative logarithm of hydrogen ion concentration (activity): pH=-lg[H+], so the potential characteristics of acid or alkali solution are related to the concentration of hydrogen ion.

The electrochemical PH glass composite electrode is based on the principle of potential difference, so the voltage between the measuring electrode and the reference electrode follows the Nernst equation.


Typical application

Source water monitoring

Filter monitoring

▲Drinking water quality monitoring

Separation process monitoring

Cooling water monitoring

Circulating water detection

Sludge treatment monitoring

Aeration tank monitoring


Features

Smart digital MEMS sensor

Sensor self-diagnosis, proactively reminding maintenance and management

Automatically completes all compensation and measurement algorithms

Quick response sensor

 IP68 Sensor

Automatic temperature compensation

Electrochemical sensor

KCl plastic gel electrolyte

PTFE porous permeable material is durable

Good robustness

Good stain resistance

The same electrode can measure PH/ORP at the same time

Fully automatic cleaning

The MEMS sensor eliminates the following problems: corrosion, contact problems, salt bridges, moisture, leakage, high resistance connections, and grounding.


Installation

Please note that the installation is more than 15 degrees above the horizontal plane, the first installation and use will take about 20 minutes of polarization time. When not in use for a long time, the PH or ORP electrode can be kept moist (the best storage solution is potassium chloride solution with pH 7 or 3mol, and it must be noted that it cannot be stored in deionized water and acid-base solutions). White potassium chloride crystals appear, which will not affect the measurement after cleaning the surface. If the sensor becomes dry during storage, you can soak the sensor in a pH 7 or 3 mol potassium chloride solution for a period of time, and the sensor will restore the water-containing glass membrane and the reference diaphragm.


Calibration

During pH calibration, wait for 5 to 10 minutes until it is stable before operation can be confirmed.


Application case

Sewage: water inlet, activated sludge and water outlet pipe.
