Works well
Tests water for hydroponic EC measurements very well. No need to spend $100. Price point for something like this is perfect, it’s not junky but isn’t extra plastic just to charge more. Accurate and plants are thriving because of it. Thank you for no gouging.

Get calibration fluid
Factory calibrated must be modern company speak for you better calibrate it yourself and not trust them. I don’t think it would be some how dishonest to be honest and tell your customers to calibrate it. Factory calibration was 50 points off. No. If deal that why you should calibrate it. Pens great and easy to calibrate lol

The accuracy and cost performance of this product are very high, recommended to buy!
I did a lot of research before I bought this product, which was also recommended by ChatGPT. After receiving the product, I tried it, and it did not disappoint me! Trust me, you don't want to know what the ppm of water in your pool is.

What’s not to like
How did I go without this matter for so long. It has greatly simplified my hydroponics and my plants are happy about that. I know exactly where my nutrients are and can make the proper adjustments. Very simple and easy to use. Highly recommended.

Reliable TDS Pen
I use this meter several times, each day, as I own a fish room and have many tanks that need attention. It seems to be working great, in every possible way. I love it.
