Water quality tester for coffee - 7 in 1 TDS meter

Sometimes "approximately" just isn't enough anymore.

The HX 7-in-1 water quality tester is designed for anyone who wants more than just a TDS value . More precision. More control. More understanding of their water – whether for coffee, drinking water, or technical applications.

Thanks to its highly sensitive probe , HD multi-parameter display , and automatic temperature compensation , the HX 7 measures quickly, stably, and reliably. Plug it in, immerse it, read the result – professional yet pleasantly uncomplicated.

🔬 7 measurements – one device

• pH value 🧪 – Acid/base balance (0.0–14.0 pH)

• TDS ⚖️ – Total dissolved solids (ppm / ppt)

• EC ⚡ – Electrical conductivity

• Temperature 🌡️ – with automatic compensation

• Salt content 🧂 – relevant for taste & technique

• ORP ⚛️ – Oxidation-Reduction Potential

• SG ⚙️ – Specific Gravity / Density

Everything visible simultaneously on a clearly structured HD display – no clicking through, no guesswork.

💡 Why the HX 7 can do more

While simple devices only provide rough guidelines, the HX 7 enables true water analysis at user level .
Ideal if you:

• If you want to optimize coffee reproducibly

• If you want to compare filter systems

• You need to monitor water long-term

• working in sensitive environments

In short: When water is not a by-product , but a crucial factor.

⚠️ Transparent notice

The HX 7 is a high-quality, practical multi-tester , not a certified laboratory reference instrument. It measures water quality. A refractometer is required for determining the TDS in brewed coffee (extraction).
However, it bridges the gap between simple TDS pens and sophisticated laboratory technology – precise enough for professionals, simple enough for everyday use .

❤️ Conclusion – who the HX 7 is made for

The HX 7 is not a toy.
It is a tool.

For everyone who uses water consciously , instead of simply taking it for granted.
For anyone who truly wants to understand their coffee, their system, or their environment.

Seven values. One glance. Clear decisions.
