Aqua Master Tools - Replacement pH Electrode with BNC Connector – Long-Life Double-Junction Glass Sensor Probe
Restore original factory baseline speed, protect your crucial fluid monitoring schedules, and eliminate unexpected facility downtime with the Aqua Master Tools Replacement pH Electrode. Purpose-built as a direct plug-and-play component for both the **Aqua Master Tools H600 Pro Substrate System** and the **P700 Pro 2 Continuous Combo Monitor**, this professional-grade sensor is engineered to handle the tough conditions of commercial indoor vertical farms, high-volume greenhouse facilities, and automated water management plants. Over months of constant contact with concentrated liquid fertilizers, chemical acids, and hard water minerals, all digital meter probes naturally experience slow sensor drift, sluggish tracking, and general glass membrane degradation. The reference liquid inside the electrode chamber gradually becomes contaminated or depleted, making the readings jump or stall out. Instead of forcing you to throw away an entire digital tool or wall monitor, the smart modular engineering of the Aqua Master Tools ecosystem allows you to simply replace the worn sensor cartridge. This high-sensitivity probe features an advanced **double-junction reference design** that isolates the internal elements from chemical fouling, vastly extending its working life compared to basic single-junction electrodes. Outfitted with an industry-standard, high-shielding **universal BNC connector**, this versatile probe securely twists into place on your existing meter socket instantly—delivering a clean, noise-free signal path to the digital processor so you can keep your water testing rounds perfectly accurate cycle after cycle.
Best For: Routine seasonal maintenance for Aqua Master Tools H600 and P700 systems, replacing worn, slow, or contaminated pH probes, restoring crisp reading response times, and maintaining essential backup inventory for commercial cultivation facilities.
Key Features & Technical Advancements
- Advanced Double-Junction Architecture: Built with a dual-chamber reference design that creates an extra layer of protection against mineral contamination, maximizing sensor longevity in active reservoirs.
- Universal Twist-Lock BNC Interface: Outfitted with an industry-standard BNC coaxial connector that provides a clean, noise-free, and immediate physical attachment to your existing monitoring unit.
- High-Sensitivity Spherical Glass Bulb: Features a premium low-impedance glass membrane that interacts smoothly with solutions to feed lightning-fast, real-time chemical acidity tracking back to your monitor screen.
- Rugged Non-Porous Protective Body: Encased in a heavy-duty polymer shield that protects the internal reference glass from physical impacts against tank walls or hard mixing equipment.
- Full 0.1 to 14.0 pH Measurement Competency: Restores full-spectrum tracking, allowing your meter to register precise, real-time chemical changes in liquid fertilizers and runoff water.
- Low-Maintenance Modular Engineering: Minimizes expensive facility downtime by letting you replace a fouled sensor cord in seconds without replacing the main digital console.

Advanced Sensor Conditioning & Substrate Control Tips
- Hydrating and Activating Your Fresh Electrode: Brand-new replacement probes are shipped with a protective cap to protect them during transit. Before using your new BNC pH electrode for the first time, you must activate the glass sensing membrane. Pour a small amount of specialized 3M KCI Electrode Storage Solution into the protective cap, stand the probe upright, and let the tip soak for at least 2 to 4 hours. This conditions the glass bulb, ensuring fast response times and stable, accurate readings on your first test.
- Root-Zone Hydration and Substrate Coordination: Keeping your testing equipment fresh ensures your liquid feeds match the specific substrate conditions your crops need to flourish. For optimal root health and fast nutrient uptake, combine your pH measurements with a high-porosity 70/30 blend of Coco Coir and Horticultural Perlite. To maintain consistent moisture levels across large benches, route your nutrient solution through lines pressurized by a heavy-duty Plont PPH Submersible Pump managed by an automated digital shot-timer.
- Executing a Full 2-Point Calibration Post-Installation: Every time you swap out a probe lead, you must re-align the meter's internal digital processor with the new sensor. Push and twist the BNC connector securely onto your H600 or P700 console, then place the probe into clean pH 7.0 calibration reference fluid and run the automatic calibration sequence. Once the meter locks in the neutral point, rinse the tip with clean water and repeat the step in pH 4.0 reference fluid to secure your baseline accuracy across the board.
- Safe Probe Cleaning and Maintenance Protocols: Never touch the glass bulb at the bottom of the electrode with your bare fingers or paper towels, as skin oils and abrasive materials can easily scratch or ruin the delicate sensing surface. If fertilizer salts or algae form on the tip, rinse it under warm tap water or soak it in a specialized cup of digital probe cleaner. Always store the electrode with a few drops of storage solution inside the cap, keeping the probe tip constantly moist to prevent premature sensor failure.
Ideal For (Uses)
- Aqua Master Tools Refurbishment: The perfect direct replacement component for commercial cultivation facilities and home growers who need to bring a sluggish or inaccurate H600 or P700 meter system back to original factory performance.
- Continuous Hydroponic Reservoir Analysis: Perfect for indoor facility technicians running constant daily acid-base checks across liquid fertilizer tanks, reverse osmosis lines, and drain runoff arrays.
- Commercial Facility Spare Parts Management: An exceptional backup component choice for commercial greenhouse operations and vertical farms looking to eliminate unexpected downtime by keeping extra replacement sensors on site.
Oversized Item Delivery Options
Oversized, heavy, and structural goods ship via specialist freight. Freight is calculated at checkout from estimated packaged volumetric or physical weight. Carrier depot audits may adjust the rate — if the increase exceeds 10%, we will contact you before processing.
Available options include:
✔ Delivery to your closest depot for pickup — default method
✔ Direct delivery — requires an operational forklift on site unless Tailgate Delivery has been specifically requested and quoted (contact us — this cannot be selected at checkout)
✔ Tailgate hydraulic lift delivery — must be specifically requested; contact us for a quote (not available as a checkout option; extra fees apply; required if you do not have a forklift)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)
Important Notes:
- Shipping costs vary by location and method
- Any carton or consignment over 25–30kg (or over 200cm) must be palletised
- Without a specifically requested and paid Tailgate Delivery quote, palletised freight requires a forklift on site — otherwise the carrier will redirect to the nearest depot
- Bulky and oversized items cannot be delivered to a PO Box — provide a physical street address
- Failed deliveries, locked gates, unattended sites, or incorrect business/forklift declarations may incur carrier redelivery, demurrage, and restocking fees as set out in our Terms & Conditions
Business Delivery:
- Selecting a business/commercial delivery rate warrants that the address has an operational forklift and certified operator during business hours
- If the carrier cannot unload, the consignment may be redirected to a depot and secondary fees may apply
- Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment
