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.
Works accurately

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 device works well. It was successfully cross-checked with another calibrated device from a different manufacturer.

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.

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.

Used for 1 month. I ordered this to check my distilled water quality that i order from the water company and it shows 0. Tap water 240. After reading a lot of reviews I settled on this product and it has been perfect! I also use test strips that show no harmful additives in my distilled or tap water.

avec le recul d'utilisation, bon produit assez précis et qui fonctionne parfaitement pour ce qu'on lui demande de faire. très bien pour une utilisation non professionnelle.
