Aqua Master Tools

Aqua Master Tools is a Dutch brand that has been making pH, EC and temperature meters since 2018. What sets it apart for us: on almost every meter the electrode can be replaced on its own. When the electrode wears out, you buy a new electrode, not a new meter.

Which meter suits you?

• Measuring one value: the P50 Pro2 for pH, the E50 Pro2 or E60 Pro2 for EC.
• pH and EC in one pen: the P110 Pro2, or the P160 Pro2 if you also want ppm or TDS.
• Measuring in the pot: the S300 Pro3 for pH and the E300 Pro2 for EC in substrate.
• Measuring a lot, or continuously: the H600 Pro handheld meter, in a liquid and a substrate version, or the P700 Pro 2 which measures in your reservoir all day.

The Pro2 pens run on ordinary AAA batteries, have a black display with white figures and remind you to calibrate after 30 days.
