Description

Technical Field

[0001] The utility model belongs to the technical field of water quality analysis and relates to a portable multi-range wide-area circulating water hardness analyzer. Background Art

[0002] Circulating water hardness is one of the important parameters in industrial water treatment, and its analysis method usually adopts titration or colorimetry. However, these traditional methods have problems such as cumbersome operation, long time consumption, low precision, etc., which are difficult to meet the needs of modern industrial production. In order to solve these problems, hardness analyzers came into being. This analyzer can quickly and accurately analyze the circulating water hardness and provide reliable data support for industrial production.

[0003] Defects and shortcomings of the existing technology:

[0004] 1. Limited measuring range: Traditional hardness analyzers usually use a few sensors or measuring cells to achieve a certain range of measurements. Due to the nonlinear characteristics of the results, the accuracy of the measurement results is low and it is difficult to meet the needs of different industrial applications.

[0005] 2. Low measurement accuracy: Since traditional analyzers use titration or colorimetry for measurement, these methods are easily affected by interfering substances, resulting in low measurement accuracy. In addition, the sensors or flow cells of traditional analyzers are prone to aging or contamination, further reducing the measurement accuracy.

[0006] 3. Complicated operation: Traditional multi-range circulating water hardness analyzers require manual titration, colorimetry and other operations, which are cumbersome, time-consuming, and prone to human errors. At the same time, traditional analytical instruments lack intelligent functions and cannot achieve automatic calibration and fault diagnosis.

[0007] 4. Unable to monitor in real time: Due to the slow measurement speed of traditional multi-range circulating water hardness analyzers, it is difficult to achieve real-time monitoring of circulating water hardness. This leads to the inability to discover and deal with problems in the industrial production process in a timely manner, which may have an adverse impact on production. Utility Model Content
