Aqua Master Tools E60 Pro2 EC, TDS and ppm meter

Measure the strength of your nutrient solution in EC, TDS or ppm, plus the temperature. Waterproof, with a replaceable electrode.

The Aqua Master Tools E60 Pro2 is the conductivity pen for growers who work in ppm or TDS, for example because a feeding chart is written that way. It shows the same measurement in the unit you want: EC up to 19.99 mS/cm, TDS up to 14.00 ppt or ppm up to 14,000.

What's new in the Pro2

• AAA batteries instead of button cells.
• Black display with white figures, easier to read.
• One or two decimals, your choice.
• Calibration reminder after 30 days.

EC, TDS and ppm: one measurement, different units

The pen always measures conductivity. TDS and ppm are a conversion of that to 'dissolved solids'. Because different conversion factors are in use, a ppm reading from one meter can differ from another. If you follow a chart in ppm, check which scale it uses. Working in EC avoids that problem.

Frequently asked questions

E50 Pro2 or E60 Pro2?
If you only work in EC, the E50 Pro2 is enough. If you also want to read TDS or ppm, choose the E60 Pro2.

Which calibration solution do I need?
Any EC calibration solution works. EC 1413 µS/cm is the most common.
