I haven’t tried it yet. It’s for measuring the quality of my filtered water and knowing when I need to change the filters.

I’m growing mini tomatoes using hydroponics, but the growth is not good, so I need to check the fertilizer concentration. I’ve been using liquid fertilizer by feel so far, but it was too low. I’m glad I bought this.

The tester arrived quickly and is as described. It measures water hardness quite well (tested with tap water – TDS approximately 0.540 – and mineral water – TDS 0.200). The only drawbacks, as noted by many, are the virtually non-existent packaging and the label directly attached to the tester itself. However, fortunately, the product is quite sturdy. A valid tester for the price paid. Reliable seller.

Haven’t checked yet. The packaging is missing, the product label is on the body. This is not good, it sticks. But it’s not a big deal.
