The pH measurement can be seen much overwhelming when you first start taking measurements. But after that, most of us face some issues while conducting tests from pH meter. Therefore, we have come up with some common mistakes people do while conducting the pH test. But before, that let us focus on the brief information about this advanced testing instrument and how it will easily help you to conduct the pH test.
The pH of the solution is considered to be one of the great indicators of product quality. Thus, with the help of the Testronix pH meter, you will be able to analyze the pH of different solutions with ease. This laboratory testing equipment will give you the accurate value of conductivity, total dissolved solids, ORP values of various test solutions and chemicals. This lab testing equipment has universal application in various sectors such as educational institutes, and research laboratories.
It comes with an in-built 1-5 point calibration system with automatic temperature compensation. This perfectly designed testing equipment has been made in compliance with industrial standards. Thus, you will be able to measure the pH of the solution and get accurate testing results. Now, let us focus on its features and technical specifications.
This lab testing instrument comes with 8 function keys with names and symbols on it to clearly describe the function key controls. Along with that, you will find different connectors located in this testing machine that will help you to connect electrodes, connect the DC 9V power adaptor, and for a connecting temperature probe.
Here is the list of several features you will get with the use of the Testronix pH meter.

When you connect the machine to conduct the test, then there are some mistakes quality analysts do. Thus, we have noticed those mistakes and curated the best possible solution to troubleshoot them. You can easily read the list of the top 3 mistakes that will be faced while conducting a pH meter test.
1. Not maintaining the electrode
The first and foremost mistake that will be done by most quality analysts is not maintaining the electrode. Since pH electrode is susceptible to dirt and contamination, clean as necessary depending on the extent and condition of use. Thus, you should clean the electrode by gently washing it with detergent and water.
2. Improper calibration of the machine
If you do improper calibration of the machine, then it will not provide you with accuracy. Thus, you should take help from our experts to calibrate your machine properly using industry standards. pH meter allows 2 point calibration, acceptable standard pH buffer solution. The standards are as follows:
- USA Standard – pH 4.01, 7.00, 10.01
- NIST Standard: pH 0.1, 6.86, 9.18
3. Using dried electrode
Another common mistake is using the dried electrode of the pH meter while conducting the test. This will give you a sluggish response. If the electrode bulb dries out, soak the electrode in the storage solution or tap water for at least 15 minutes.
These are the top 3 common mistakes that should be avoided while conducting the test with the help of a pH meter.
