Aqua Master Tools – replaceable pH electrode H600 Pro Substrate H600 Pro, P700 Pro 2, S300 Pro 2

Aqua Master Tools Replaceable pH Substrate Electrode (BNC)Genuine replaceable pH electrode with a reinforced Substrate design, engineered for measuring pH directly in growing media (soil, coco, rockwool) as well as liquids. Compatible with H600 Pro Substrate, H600 Pro, P700 Pro 2, and S300 Pro 2 models. Replacing just the probe saves you the cost of buying a whole new meter.Key Features:BNC Connector: Standard plug ensuring a stable, interference-free connection and simple installation.Substrate Design: Specially built to withstand direct insertion into growing mediums (soil, mineral wool, coco).Modular Design: Quick and easy DIY replacement in case of failure or wear of your old probe.When to replace the electrode?Due to natural aging of the sensor (slow readings, calibration issues).If the electrode dries out or the glass bulb cracks.In case of mechanical damage or hardening of the cable.⚠️ Please note: After installation, the new electrode must be calibrated using pH buffer solutions (pH 4.01 / 7.00). Always store the probe in its protective cap with a few drops of storage solution (KCL).Note: dried salts around the pH electrode are normal and not a cause for concern.It is important to soak the electrode in tap water for at least 12 hours before use. This helps dissolve the salts and ensures the electrode is properly activated.
