Aqua Master Tools - P160 Pro Replacement Electrode – High-Precision 5-in-1 Multiparameter Sensor Cartridge
Restore ultimate factory precision, lock in error-free water quality data, and protect your vital crop feeding channels with the Aqua Master Tools P160 Pro Replacement Electrode. Explicitly designed as the direct, plug-and-play replacement sensor cartridge for the elite P160 Pro Combo Pen Meter, this professional-grade component is engineered to withstand the demanding, continuous-use conditions of commercial vertical indoor farms, high-volume greenhouse ranges, and agricultural testing labs. Over months of heavy exposure to highly concentrated liquid fertilizers, aggressive reservoir additives, and fluctuating water temperatures, all multiparameter sensors naturally experience glass membrane degradation, mineral fouling, and slow sensor drift. Rather than forcing you to purchase an entirely new handheld digital console, the smart modular engineering of the Aqua Master Tools ecosystem allows you to simply refresh your device by swapping out the worn sensor cartridge. This high-performance probe houses an advanced 5-in-1 array that feeds real-time chemical acidity (pH), electrical conductivity (EC), total dissolved solids (TDS), parts per million (PPM), and fluid temperature data back to your digital screen instantly. Fitted with a heavy-duty threaded compression collar and a premium rubber O-ring, it establishes a perfectly airtight, watertight mechanical seal that preserves your combo meter's certified IP67 dust-tight and submersible floating rating. Pre-calibrated to integrate seamlessly with the P160 Pro's automatic pH and temperature-independent analog manual EC calibration systems, this durable replacement sensor slides into position without requiring manual wiring or specialized tools, ensuring your everyday water testing rounds remain flawless cycle after cycle.
Best For: Routine seasonal maintenance for Aqua Master Tools P160 Pro combo meters, replacing worn, sluggish, or cracked multi-sensor probes, restoring rapid reading stabilization times, and maintaining essential backup inventory for commercial cultivation operations.
Key Features & Technical Advancements
- 5-in-1 Integrated Multiparameter Array: Houses high-sensitivity pH glass, heavy-duty electrical conductivity rings, and a fast-response thermal sensor inside a single, streamlined cartridge body to deliver complete solution profiles simultaneously.
- Innovative True Dry-Storage Sensor Matrix: Engineered with Aqua Master Tools' advanced dry-storage technology, eliminating the need for messy liquid storage caps, sponges, or KCI storage solutions.
- Watertight Threaded Mechanical Interface: Engineered with an airtight locking sleeve and a durable rubber seal that maintains your combo meter's certified IP67 waterproof and buoyant floating competency.
- Rugged Non-Porous Shielding Shell: Encased in a heavy-duty polymer protective guard that shields the internal sensor elements from bumps against tank walls or hard mixing equipment.
- Immediate Plug-and-Play Assembly: Built with precision connection pins that slide smoothly into the main P160 Pro meter handle, completely cutting out hardwiring or specialized electrical tools.
- High-Stiffness Contact Terminals: Outfitted with corrosion-resistant internal terminals that ensure steady, noise-free signal transfer to the digital processor for clean, uncompromised telemetry.
- Fast-Response Thermal Synchronization: Built to align perfectly with the auto-temperature compensation routines of your existing Aqua Master Tools meter handle to ensure steady readings.

Advanced Multi-Parameter Testing & Substrate Control Tips
- Optimizing Hydroponic Reservoirs with Full-Spectrum Telemetry: Plants require carefully balanced water chemistry to thrive and avoid root stress. When mixing liquid fertilizers, use your refreshed P160 Pro to double-check your targets. For crops in coco coir or hydroponics, adjust your nutrient solution to hit a tight 5.5 to 6.5 pH buffer, while managing your electrical conductivity (EC) based on growth stage—keeping early starts around 0.8 to 1.2 mS/cm and ramping up to 1.8 to 2.5 mS/cm for heavy-feeding mature canopies.
- Root-Zone Hydration and Substrate Coordination: Keeping your medium's salt and chemical profiles balanced allows your root network to absorb nutrients at peak efficiency. For the best structural airflow and fast nutrient uptake, pair your liquid 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 the Deviation-Free Analog EC Calibration Post-Installation: Every time you swap out a probe cartridge, you must re-align the meter's internal digital processor with the new sensor elements. Screw the fresh electrode tightly onto the P160 Pro handle. Perform the 2-point pH calibration sequence by dipping the tip into clean pH 7.0 reference fluid, letting it auto-tune, and then repeating the process in pH 4.0 fluid. Next, pour fresh 1413 μS/cm calibration solution into a clean plastic cup, submerge the probe tip, and use the micro-screwdriver to gently adjust the manual calibration trimmer on the body until the screen locks solidly onto 1.4 mS/cm. Always rinse the sensor with clean water between steps.
- Capitalizing on Advanced Dry-Storage Maintenance Routines: Unlike older style pocket pens that will ruin if left dry, the P160 Pro replacement electrode is explicitly optimized for dry storage. After completing your daily reservoir or runoff quality checks, rinse the probe tip thoroughly under clean tap water to remove clinging fertilizer salts and organic residues. Shake off the excess water droplets and snap the protective cap straight back into place. Do not add wet sponges or electrode storage solution to the cap, as this can degrade the specialized sensor matrix.
Ideal For (Uses)
- Aqua Master Tools P160 Refurbishment: The ultimate direct repair option for commercial cultivation facilities and home growers who need to bring a slow or inaccurate P160 Pro flagship pen meter back to original factory-spec performance.
- Hydroponic Reservoir Fertilizer Analysis: Perfect for indoor facility technicians running constant daily nutrient strength (EC), TDS, PPM, and acidity (pH) checks across liquid mixing tanks, reverse osmosis loops, 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.

Important Note on Availability & Shipping
Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.
Lead Times:
- In-Stock Items: Usually ready for dispatch the same day.
- Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.
While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.
Biosecurity & Interstate Shipping Restrictions
Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:
