Adwa AD202 Pros/Cons and My Thought
The Adwa AD202 is a pocket-sized TDS meter that measures the total dissolved solids (TDS) in water. TDS is a measure of the amount of impurities in water, and it can be used to determine the quality of water for drinking, swimming, and other purposes.
The AD202 has a number of pros, including:
- Accurate readings: The AD202 is known for its accurate readings, even in challenging conditions. It has a built-in automatic temperature compensation feature that ensures accurate readings regardless of the ambient temperature.
- Easy to use: The AD202 is very easy to use. Simply turn it on, submerge the electrode tip in the water sample, and wait for the reading to appear on the display. The display is large and easy to read, and it also shows the full-scale readout so you can get an accurate reading even if the TDS level is very high.
- Durable: The AD202 is made from durable materials and is splash-proof, so you don't have to worry about damaging it if it gets wet.
The AD202 also has a few cons, including:
- Not calibrated: The AD202 does not come pre-calibrated, so you will need to calibrate it yourself before using it. This is a relatively simple process, but it can be a bit time-consuming.
- Not very sensitive: The AD202 is not very sensitive, so it may not be able to detect low levels of TDS.
- Not very versatile: The AD202 can only measure TDS, so it cannot be used to measure other water quality parameters such as pH or chlorine.
Overall, the Adwa AD202 is a good TDS meter for the price. It is accurate, easy to use, and durable. However, it is not calibrated and not very sensitive, so it may not be the best choice for all applications.
Here are some user reviews of the Adwa AD202:
- Positive review: "I've been using this TDS meter for a few months now and I'm very happy with it. It's accurate, easy to use, and it's helped me keep my aquarium water clean and healthy. I would definitely recommend it to anyone who needs to measure TDS in water."
- Negative review: "I was disappointed with this TDS meter. It's not as accurate as I expected, and it's not very sensitive. I also found the calibration process to be a bit complicated. I would not recommend this meter to anyone."
My thoughts on the Adwa AD202 are that it is a good TDS meter for the price. It is accurate, easy to use, and durable. However, it is not calibrated and not very sensitive, so it may not be the best choice for all applications. If you are looking for a simple and accurate way to measure TDS in water, then the Adwa AD202 is a good option. However, if you need a more sensitive or versatile TDS meter, then you may want to consider a different model.
