Aqua Master Tools – replaceable EC electrode H600 Pro Substrate, H600 Pro, E300 Pro

Aqua Master Tools Replaceable EC Substrate Electrode (Small PIN)Genuine replaceable EC electrode with a reinforced Substrate design, engineered for precise electrical conductivity (EC) measurements directly in growing media (soil, coco, rockwool) as well as liquids. Fully compatible with H600 Pro Substrate, H600 Pro, and E300 Pro meters. It allows for quick and easy replacement of just the probe, saving you the high cost of buying a whole new device.Key Features:Substrate Design: Specially reinforced measurement tip, built for safe insertion and reliable operation in various growing mediums.Stable Connection (Small PIN): The compact PIN plug ensures a secure connection to the meter, quick installation, and zero signal interference.Fully Modular: Unlike most meters on the market that do not allow probe replacement, Aqua Master Tools gear lets you swap it yourself in seconds, saving you both time and money.When to replace the EC electrode?Due to natural aging of the sensors (loss of accuracy, calibration difficulties).If a thick, unremovable layer of limescale builds up on the electrode.In case of casing leakage or cable damage (hardening over time).⚠️ Please note: After installation, the new electrode must be calibrated using the appropriate EC buffer (calibration) solution before taking your first measurement to ensure 100% accuracy.
