1. The characteristics of a pH meter are that the glass on the pH electrode gradually ages over time, and the gradient (the change in electrode output potential caused by a change in unit pH value) deteriorates, taking a long time to reach a stable potential. The service life of general electrodes can reach two years. In addition, temperature also has a significant impact on aging. The degree of aging after several weeks of storage at 100 ℃ is equivalent to the degree of aging after one year of storage at room temperature. The pH meter has the advantages of high accuracy, high reliability, easy installation and maintenance, and is also sensitive to pollution. It needs to be calibrated regularly, usually every one to one and a half months, and the electrode needs to be replaced every two years.

2. The characteristics of the dissolved oxygen meter include easy installation, long calibration cycle (3-4 months), insensitivity to other substances, and the ability to monitor the use of electrolytes in the diaphragm and probe. Generally, electrolytes and diaphragms are replaced every one to three years.

The COM252 dissolved oxygen transmitter is an intelligent instrument with HART or Profibus communication protocol and self diagnostic function.

Various measurement methods are needed to complete experiments during water quality analysis and monitoring. Due to the fact that the measured numerical form cannot usually be represented by a finite number of digits, and due to insufficient cognitive ability and limitations in scientific and technological level, the measured value does not necessarily match its true value. This contradiction is manifested in numerical terms as error. Any measurement result has errors, which exist throughout the entire measurement process. The so-called true value refers to the objective or actual value reflected by the effect of a certain quantity at a certain moment and in a certain position or state.
