Precision-engineered for commercial greenhouse growers, indoor vertical farmers, and professional agronomists, this premium handheld analyzer is specifically designed to measure acidity and temperature directly inside soft substrates, moist soil blends, coco coir matrices, and liquid nutrient solutions. Standard glass pocket pens are built exclusively for open water testing and will easily snap or crack if forced directly into compressed planting mediums. The S300 Pro 2 resolves this operational hazard by decoupling the heavy-duty spear-tipped pH electrode from the main digital housing, linking them via an extended, ultra-flexible 120cm connection cable. This durable design gives you the physical reach to sample ground beds, deep fabric pots, and elevated rockwool slabs with absolute ease. Upgraded with enhanced internal software, the S300 Pro 2 processes data faster and locks in precise, real-time measurements across a wide pH spectrum from 0.1 to 14.0 and thermal conditions from 0°C to 50°C. Setup is completely streamlined by a 2-point automatic calibration function calibrated for standard pH 4.0 and pH 7.0 reference buffers, doing away with manual turning pins and complex configuration loops. Arriving fully calibrated and ready to work with pre-installed batteries in a lightweight 158g frame, this field-ready kit features a modular, user-replaceable electrode socket that allows you to easily swap out worn or damaged probes down the road, ensuring long-term usability and maximizing your facility's equipment lifespan.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Direct root-zone testing in soil and coco coir mixes, measuring rockwool slab runoff, chemical telemetry in soft organic substrates, and mobile multi-zone facility inspections.\u003c\/p\u003e\n\u003ch3\u003eKey Features \u0026amp;

For compressed coco coir blocks or dense organic soils, use a clean metal spike or dibbler to create a small pilot pathway first, then gently slide the S300 Pro 2 spear probe down into the root core. This structural step shields the delicate glass sensing membrane from unnecessary physical grinding against hard pearlites or uncomposted wood bits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoot-Zone Hydration and Substrate Coordination:\u003c\/strong\u003e Keeping your medium's chemical profile balanced allows your root network to absorb nutrients at peak efficiency.

To keep moisture levels flawlessly uniform across large benches, feed your trays with a high-pressure \u003cstrong\u003ePlont PPH Submersible Pump\u003c\/strong\u003e managed by an automated digital shot-timer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintaining the Detachable Electrode and Preventing Drift:\u003c\/strong\u003e The high-precision glass tip on the S300 Pro 2 sensor must never be allowed to dry out completely. After wrapping up your soil tests, thoroughly rinse the probe tip with fresh tap water or a specialized wash bottle to clear away clinging substrate dirt and sticky fertilizer salts. Slide the probe into its protective guard filled with a few drops of specialized \u003cstrong\u003e3M KCI Electrode Storage Solution\u003c\/strong\u003e before storing it away. Avoid wiping the tip with paper towels, as static charges can cause severe digital reading drift.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExecuting a Complete 2-Point Electronic Alignment:\u003c\/strong\u003e To maintain your S300 Pro 2 at peak factory precision, run a 2-point calibration check every two weeks. Dip the spear probe into a clean cup of pH 7.0 reference liquid, let the meter auto-stabilize, and lock in the neutral baseline. Rinse the tip with fresh water, then repeat the step inside a cup of pH 4.0 reference liquid to calibrate the acid range. Always discard your used testing fluids to keep your main calibration supply clean and unpolluted.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIdeal For (Uses)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Soil \u0026amp; Coco Coir Profiling:\u003c\/strong\u003e The premier handheld option for greenhouse growers and vertical farming teams who need to measure root-zone pH levels directly inside pots and soil beds without stirring up messy slurry mixes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommercial Multi-Zone Substrate Testing:\u003c\/strong\u003e Perfect for crop facility managers and agronomists who need a mobile, flexible meter with an extended 120cm cord to quickly check different benches, slabs, and drainage points.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorticultural Nursery Quality Control:\u003c\/strong\u003e An exceptional tool choice for commercial seedling farms and potting soil producers looking to verify chemical consistency and uniform acidity across large production runs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e","brand":"Holland Forge","offers":[{"title":"Default Title","offer_id":48455172423780,"sku":"4398","price":218.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/AquaMasterS300PRO2SubtratepH.png?v=1779618829","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/aqua-master-tools-s300-pro-2-handheld-digital-substrate-ph-temperature-meter-heavy-duty-soil-coco-medium-penetration-probe","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
