Total Dissolved Solids (TDS) meters are essential to measuring the purity of water, and you know it. But have you considered how long you can measure water quality using one TDS meter? Well, that depends.  

The warranty period the manufacturers offer for the TDS devices is up to three years. It means you can use a TDS meter for up to three years with the standard use. Due to specific factors such as the quality of water, your method of use, and the environmental factors, that maximum period may reduce. 

In this article, we will discuss some easy-to-follow tips to maximize the life of your TDS meter.

You must keep the electrodes clean

The electrodes are the most critical part of your TDS meter, as they touch water every time you measure it. 

Over time, the electrodes may get contaminated by various things, such as minerals, dirt, and other debris. Also, they may affect the accuracy of readings. In the same way, you may not be able to use the TDS meter due to broken or faulty electrodes. 

After each use, you must keep electrodes clean by rinsing them with distilled water. You must use a soft-bristled brush to remove any debris. 

Note: You must avoid using abrasive materials that can scratch the electrodes.

Calibrate your TDS meter regularly

Calibration is the process of adjusting your TDS meter to ensure its accuracy. You must continuously do that as it readjusts the settings of the TDS meter and prevent you from purchasing a new one. 

The frequency of calibration depends on several factors. But, mainly, it depends on how often you use your meter and the type of water you use to test. The usual recommendation to calibrate your TDS meter is once every six months. Also, if you use it regularly, you must calibrate it after 50-100 uses. 

You may use a standard calibration solution provided by the manufacturer or prepare a calibration solution at home. Also, the calibrating steps may vary from one TDS manufacturer to the other. 

Storing the TDS meter properly

 Properly storing your TDS meter causes it to extend its life. After use, you must keep it after sweeping it from a cloth. Since most of the TDS meters come with clips or plastic guards, you can also cover them using those clips. 

You must avoid storing your TDS meter in direct sunlight or extreme temperatures. The reason is they may damage the electrodes and affect their accuracy. You are recommended to store your meter in a cool, dry place.

Use the TDS meter for its intended purpose Only 

TDS meters are specifically designed for measuring the TDS of water. You must always test the clean water as clean water is what you usually drink. Manufacturers have mentioned in the instructions that you must not test water that may spread in a vast range as it may affect the device’s accuracy. 

You must not use TDS meters for other purposes, such as measuring chemicals, food, drinks, solutions, or even muddy water. 

Replacing the batteries when needed

Most TDS meters are powered by batteries. The type of the battery and the number of the batteries. If the battery level is low, or between 10-20% of their capacity, an indication is available for most of the TDS devices. You must replace it as soon as possible as the dead batteries may cause trouble.

Also, you must use quality batteries recommended by the TDS manufacturer. There have been numerous corrosive material depositions on the battery cartridges due to the use of low-quality batteries.

Handling your TDS meter with care

TDS meters are delicate instruments that are made of plastics and electronics mainly. They require careful handling for long use. Electrodes must be specifically protected from mechanical damage and shocks. You must Avoid dropping your meter or exposing it to physical shock, as they damage the electrodes. 

What Are the Essential Steps to Maximize TDS Meter Accuracy?

To ensure accurate readings with TDS meters, several steps can be taken. First, calibrate the meter using a reference solution to establish a baseline. Next, clean the electrodes regularly to remove any buildup or contaminants. Additionally, use the appropriate temperature compensation feature for precise measurements. Finally, handle the meter with care and store it properly to avoid damage. By following these essential steps, maximizing accuracy with tds meters can be achieved effortlessly.

Use the device Under recommended conditions

You will see in the instructions that the manufacturer has specified the temperature, humidity, and various conditions to use the TDS meter.

You must always conduct the testing under those circumstances in order to get accurate data. If the reading is faulty, it means it requires calibration. The more you calibrate the TDS meter, the quicker its expiry data gets. 

Final Thoughts

The TDS meter is a valuable tool for measuring water purity. You can extend the life and accuracy of your TDS meter simply by following these steps and getting the service of the same device for a long time. You can refer to the manufacturer’s instructions for specific instructions as well.
