The second-generation portable acid concentration analyzer was developed as a new generation of intelligent portable acid concentration analyzer based on the feedback of current sulfuric acid analysts and sulfuric acid plant managers regarding the existing problems in sulfuric acid concentration analysis.

I. Problems Existing in the Current Analysis of Sulfuric Acid Concentration

1. The alkaline solution titration method takes a long time for analysis and the measurement results need to be calculated manually. Its operation is complicated and is prone to interference from human errors. Parallel sample tests are required to verify the accuracy of the results.

2. Using imported acid concentration analyzers also has the problem of long measurement time, and they have strict requirements for the on-site environment and high maintenance costs. The data stability is affected by temperature, and manual calibration and frequent calibration are needed. In practical applications, there are problems such as cumbersome operation and poor adaptability. The final measurement results need to be judged by the analysts based on the closest curve, and any slight oversight can lead to deviations in the results.

3. After each analysis, personnel need to record the measurement results promptly. A little carelessness can easily cause recording errors or omissions.

4. Both manual analysis and instrument analysis require precise sampling and pre-treatment of the measured samples. Any slight mistake can affect the reliability of the final results.

2. Overview of Portable Acid Concentration Analyzer

To address the aforementioned issues, the second-generation portable acid concentration analyzer employs a high-precision conductivity and temperature compensation integrated sensing technology, with an internal intelligent algorithm model. It can quickly determine the concentration of sulfuric acid within 60 seconds. The measurement results can be directly read without the need for manual calculation or interpretation, and the measurement results will be automatically saved, supporting historical data traceability and comparative analysis.

This instrument has an automatic temperature compensation function, which can effectively eliminate the impact of environmental temperature differences on measurement accuracy, eliminating the need for frequent calibration. During each analysis, only the sample to be analyzed needs to be poured into the measuring cup. It can also be equipped with a sulfuric acid sealed sampling device. Using the measuring cup for sampling can complete the sampling and measurement integration operation, avoiding human error.

The instrument adopts advanced protection design, capable of adapting to harsh working conditions such as high temperature, high humidity, and strong corrosion, ensuring stable and reliable data. Innovative changes bring non-contact analysis technology that can make the measurement of sulfuric acid concentration accurate, efficient, and safe, providing support for high-quality green production and intelligent analysis in the sulfuric acid industry. The instrument is designed for lightweight, with a total weight of only 2.2kg, making it easy to carry and operate on-site.

The instrument is equipped with a high-precision conductivity detection module and a temperature sensor, combined with non-contact measurement technology, can simultaneously complete the determination of acid concentration and acid temperature within 60 seconds, with a measurement accuracy of ±0.02%. It supports automatic storage of multiple points of data, with a data storage capacity of up to 10 years of records, and can also achieve rapid export and analysis of data through the USB interface.

This instrument is suitable for rapid measurement of sulfuric acid concentration in the production, storage, and transportation processes of sulfuric acid, ensuring process safety and stable product quality. The instrument is equipped with a high-strength protective shell, capable of long-term use in complex industrial environments, and also has IP65 level dustproof and waterproof performance. Its screen uses high-brightness liquid crystal display, which remains clearly visible even in strong light. Additionally, a lithium battery version is available, allowing for on-site operation without the need for an external power source, enabling immediate measurement upon startup, significantly improving detection efficiency.

This equipment performs stably in rapid screening of sulfuric acid concentration in multiple devices, becoming the preferred tool for process control and safety inspection. Its non-contact measurement technology effectively avoids the drawbacks of traditional electrode-type sensors, such as corrosion and contamination, significantly increasing service life and stability.
