PH analyzer manufacturer Era New Wei pH meter pH meter Three composite electrode

Used in industries such as industry, electricity, agriculture, medicine, food, scientific research, and environmental protection. Such as wastewater treatment, purified water, and recycling

Water, boiler water and other systems, as well as large-scale wastewater treatment plants for electronics, electroplating, printing and dyeing, chemistry, food and other industries, chemical industry, and production

Measurement of pH and dissolved oxygen values for pure water, water, and wastewater in physical engineering, power plants, and other fields.

The instrument adopts a potentiometric analysis method, mainly consisting of a measuring battery and a high resistance millivolt meter (or ion meter). The primary battery consists of a measuring electrode (indicator electrode), a reference electrode, and the measured liquid, which converts difficult to directly measure chemical quantities (ion activity) into easily measurable electrical quantities (measuring the electromotive force of the battery). The relationship between the electrode potential under non-standard conditions and the activity and temperature of ions in the solution is obtained by the Nernst equation.

lThe instrument adopts high-precision AD conversion and single-chip microcomputer processing technology, which can achieve various functions such as conductivity measurement, temperature measurement, automatic temperature compensation, and automatic range conversion.

lHigh precision composite electrode, accurate and convenient measurement.

lAdvanced surface mount technology and integrated design, high integration circuit design is stable and durable.

lData loop storage function, automatically clearing overflow

lData, easy to operate, easy to query, with a power-off data storage time of over 10 years.

lChinese main menu operation, easy to understand, quick and convenient to operate.

lDisplay multiple parameters simultaneously, including pH value, temperature, time, and status on the same screen.

l5.0-inch touch color LCD, Chinese display, easy to operate.

Precautions

1. The electrode must be buffered with a known pH standard before measurement

To calibrate the liquid and improve measurement accuracy, buffer solution is used

The pH value should be accurate and reliable.

2. The sensitive glass bulb at the front end of the electrode should not come into contact with hard objects,

Any damage or scratching will cause the electrode to fail.
