With the popularization of acidity meter, more and more users are interested in digital display pH meter | digital display pH meter | digital pH meter | digital pH meter | laboratory pH meter | precision pH meter | intelligent pH meter | Microcomputer precision pH meter | PH meter | precision PH meter | online PH meter quality, so Shanghai Long Tuo lower down roughly to determine the number of commonly used methods to determine the pH meter is good or bad.
From the use point of view, digital display pH meter | digital display pH meter | digital pH meter | digital display pH meter | laboratory pH meter | precision pH meter | intelligent pH meter | microcomputer precision pH meter | PH meter | precision PH meter | Online PH meter judgment mainly reflected in:
1. Accuracy: The pH meter with no accuracy has no use value. The way to judge is to use high-precision instruments or high-precision standard fluid calibration.
2. Stability: An unstable digital display pH meter | Digital display pH meter | Digital pH meter | Digital display pH meter | Laboratory pH meter | Precision pH meter | Intelligent pH meter | PH meter | precision PH meter | online PH meter reading difficulties, it is difficult to ensure the accuracy of the instrument, the stability of performance in two aspects, on the one hand is a single digital display pH meter | digital display pH meter | digital PH meter | Digital Display Acidity Meter | Laboratory pH Meter | Precision Acidity Meter | Intelligent pH Meter | Microcomputer Precision Acidity Meter | PH Meter | Precision PH Meter | Online PH Meter Stability, Can Show the Same Digital pH Meter | Digital Display pH Digital pH meter|Digital display acidity meter|Lab pH meter|Precision acidity meter|Intelligent acidity meter|Microcomputer precision acidity meter|PH meter|Precision PH meter|On-line PH meter for long time stable solution, see value Whether the change and the magnitude of change; the stability of multiple instruments on the other hand, put several instruments of the same type that have been calibrated into the same stable solution to see if the readings are the same, and how much the error is, if several instruments of the same model cannot Guaranteed stability , it is difficult to ensure the accuracy and stability of each instrument.
3. Adjustment of common errors: Temperature is the most obvious factor that causes the pH/acidity error. Whether there is a temperature probe and the sensitivity of the temperature probe also affect the use of the instrument.
4, easy to operate, beautiful interface: Users in this regard is relatively easy to determine, some old-style instruments, the use of analog switches, resulting in difficult calibration, small changes are not easy to find, prone to fatal system errors. On the other hand, taking into account the cost and technical reasons, there are still many instruments using LED digital tube, the display content is not enough, of course, there are manufacturers to make up for this shortcoming in a certain way. At present, more commonly used convenient operation interface is generally LCD liquid crystal display + keyboard type operation.
5, the pros and cons of the probe: this is undoubtedly, the performance of the probe directly affects the digital display pH meter | digital display pH meter | digital pH meter | digital display acidity meter | laboratory pH meter | precision pH meter | intelligent pH meter Microcomputer precision pH meter|PH meter|Precision PH meter|Some technical indicators of online PH meter, superior digital display pH meter|Digital display pH meter|Digital pH meter|Digital display pH meter|Lab pH meter| Precision pH Meter | Intelligent pH Meter | Microcomputer Precision Acidity Meter | PH Meter | Precision PH Meter | Online PH meter equipped with poor quality probes are of no avail.
6, security: In recent years, more and more customers began to pay attention to the safety of the operation, a well-designed instrument using a lower safety voltage input can greatly improve the safety performance.
From a technical point of view, it is mainly reflected in:
1. Design Principle: The design principle is the entire digital display pH meter | digital display pH meter | digital pH meter | digital display acidity meter | laboratory pH meter | precision acidity meter | intelligent acidity meter | microcomputer precision acidity meter | PH meter | precision PH meter | Online PH meter's soul, excellent design can reduce the cost while improving the accuracy, this point everyone sees wisdom, benevolent see. However, one of the biggest differences is the difference between analog circuits and numerical circuits. With the development of technology and the decrease in the price of single-chip computers, numerical circuits have increasingly become mainstream products in recent years. Many of his advantages are incomparable with analog circuits.
2. Production process: no matter how good the design, no matter how good the digital display acidity meter | digital display pH meter | digital pH meter | digital display acidity meter | laboratory pH meter | precision acidity meter | intelligent pH meter | microcomputer precision pH meter | PH meter | precision PH meter | online PH meter, if there is no good production process and inspection methods is useless, the manufacturing process is mainly reflected in the internal lines and components, many units take into account the cost and technology, the internal circuit is disorderly and rough, Or use low-quality components, such digital display pH meter | digital display pH meter | digital PH meter | digital display pH meter | laboratory pH meter | precision pH meter | intelligent pH meter | microcomputer precision pH meter | PH meter | precision PH meter | online PH meter can not guarantee his long-term accuracy and stability and safety.
