Apax Lab TDS Meter

Designed for measuring mineral concentration in brewing water, the Apax Lab TDS Meter provides a fast and straightforward way to monitor Total Dissolved Solids (TDS) during coffee preparation. By measuring conductivity and converting it into a PPM reading, it helps verify mineral concentration, check dilution levels and maintain more consistent brewing conditions when working with custom water or mineral concentrates.

Compact and easy to use, the meter features a simple one-button interface with fast readings and an integrated hold function for recording measurements. Whether you’re building water from scratch or refining a mineral recipe, it gives you a clearer understanding of how water composition is affecting flavour and extraction.
