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.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch3\u003eKey Features \u0026amp;

Before using your new BNC pH electrode for the first time, you must activate the glass sensing membrane. Pour a small amount of specialized \u003cstrong\u003e3M KCI Electrode Storage Solution\u003c\/strong\u003e into the protective cap, stand the probe upright, and let the tip soak for at least 2 to 4 hours.

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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafe Probe Cleaning and Maintenance Protocols:\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIdeal For (Uses)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAqua Master Tools Refurbishment:\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Hydroponic Reservoir Analysis:\u003c\/strong\u003e Perfect for indoor facility technicians running constant daily acid-base checks across liquid fertilizer tanks, reverse osmosis lines, and drain runoff arrays.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommercial Facility Spare Parts Management:\u003c\/strong\u003e An exceptional backup component choice for commercial greenhouse operations and vertical farms looking to eliminate unexpected downtime by keeping extra replacement sensors on site.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e","brand":"Holland Forge","offers":[{"title":"Default Title","offer_id":48455248543844,"sku":"4399","price":104.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/ChatGPTImageMay24_2026_09_28_36PM.png?v=1779629338","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/aqua-master-tools-replacement-ph-electrode-with-bnc-connector-long-life-double-junction-glass-sensor-probe","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
