Digital 4-in-1 TDS Meter HA 2

The HA 2 is a compact meter for quick, comparative water checks. It measures TDS, electrical conductivity (EC), temperature and salinity.

TDS and EC can help compare changes in water or filtration. On their own, however, they do not show the complete mineral composition, water hardness or alkalinity and therefore cannot by themselves determine whether water is optimal for a particular coffee preparation.

Measurement ranges

• TDS: 0–9999 ppm
• EC: 0–9999 µS/cm
• Temperature: 0–80 °C
• Specified measurement accuracy: ±2%

Features

• Automatic temperature compensation
• Display
• Three-button operation
• Power supply: 2 × LR44
• Dimensions: 155 × 30 × 14 mm
• Weight: approx. 50 g

The device is suitable for indicative and comparative measurements of tap, filtered and treated water and for comparing water values in coffee workflows.

Note: The HA 2 measures water. A suitable coffee refractometer is required to measure TDS in brewed coffee and calculate extraction yield. The device is not a laboratory reference instrument and does not replace any legally required, official or accredited drinking-water, food or laboratory test.
