The acid-base concentration meter has no zero drift phenomenon after long-term use
The acid-base concentration meter is a water quality online monitor with a microprocessor. The acid-base concentration meter indirectly measures the concentration of the solution by measuring the conductivity of the solution. It is known that at a certain constant temperature, the conductivity of the low-concentration electrolyte corresponds to the concentration of the solution. When the temperature changes, the conductivity also changes, ie the concentration of the solution is a function of conductivity and temperature. It should be emphasized that the concentration of the solution is the sum of the conductivity of all conductive ions in the water. If there are two or more conductive components in the water and the above data of concentration-temperature-conductivity can be measured, this instrument can also be used. Measurement; if the ratio of the conductive composition in water is uncertain, the meter cannot be used for measurement.
The main features of the acid-base concentration meter:
No need for zero adjustment, high precision: the audio frequency conversion excitation power supply and resonance circuit and its unique signal sampling method are used to replace the single frequency excitation method of traditional products, which increases the output voltage of the detection transformer by hundreds of times and greatly improves the performance of the instrument. precision and stability.
Long-term use without zero drift phenomenon: low magnetic leakage structure and ferromagnetic shielding, ferromagnetic substances near the sensor will not affect the zero point of the instrument.
The display value is stable: the sensor is equipped with a gas-water separator, which can eliminate the influence of air inhalation due to air leakage of the acid-base injector or entrained air bubbles in the water sample on the measurement results.
Highly intelligent, high-precision temperature compensation
The acid-base concentration meter adopts frequency conversion excitation power supply and resonance circuit and its unique signal sampling method to replace the single frequency excitation method, so that the output voltage of the detection transformer is increased several hundred times. The flow-through sensor adopts a low-temperature magnetic structure and ferromagnetic shielding, and has no zero-point drift phenomenon, which greatly improves the accuracy, sensitivity and stability of the instrument. The acid-base concentration meter is mainly used to monitor the concentration of the regeneration solution of the ion exchanger in the process of producing high-purity water by the ion exchange method, or to prepare the pickling solution for boilers and pipelines, and to continuously monitor the concentration of hydrochloric acid in the solution.
The acid-base concentration meter is an intelligent instrument widely used in electric power, petrochemical, metallurgy and other industries to measure the concentration of ion exchanger regeneration solution. Using technical means such as screen display, Chinese menu, guided operation, graphic curve, data recording, etc., the performance of the whole machine is stable, easy to operate, and requires no maintenance.
