Aqua Master Tools EC meter E300 PRO 2.0 (EC, temperature) for substrate

Professional EC and temperature measurement for your plants

Ensure optimal growing conditions for your plants with the digital EC/Temp meter E300 Pro. This handheld meter is designed to accurately and reliably measure electrical conductivity (EC) and temperature directly in soft substrates such as soil or coconut, as well as in liquids. Its robust design and high accuracy make it an indispensable tool for growers of annuals, herbs or vegetables, whether for home growing or commercial use.

Key benefits of the E300 Pro

• Almost unbreakable electrode: The specially designed EC electrode can withstand even heavy use and ensures long-term reliability.
• Maximum flexibility.
• Replaceable probe: You can easily extend the life of the instrument by simply replacing the electrode once it has reached the end of its life.
• Automatic temperature compensation.
• Easy calibration. An indicator on the display confirms successful execution.
• Water resistance: The instrument is IP65 waterproof certified and the electrode is even IP67 certified, so you don't have to worry about damage during normal use and cleaning.

Designed for practice

The E300 Pro has been developed with everyday work in mind. The modern and durable case with ergonomic rubber back fits perfectly in the hand and does not slip. The large display shows the values legibly and the buttons are easy to operate. The HOLD function allows you to hold the reading on the display so you can write it down at your leisure. To save energy, the instrument automatically switches off after 8 minutes of inactivity.

How to use the E300 Pro

Taking measurements with this instrument is quick and intuitive:

1. Connect the PIN connector of the electrode to the EC meter.
2. Rinse the electrode with clean water and gently dry it before each measurement.
3. Switch on the instrument by pressing the On/Off button.
4. Immerse the electrode in a soft, sufficiently moist substrate or liquid. Sufficient moisture is essential for correct measurement.
5. Wait until the value on the display is stable.
6. Press the HOLD button to temporarily save the value. Press it again to deactivate it before the next measurement.
7. Always rinse the electrode thoroughly with clean water after use to ensure no residue remains on the electrode.
