Premium Series Pocket pH/Conductivity/TDS/Salinity/ORP Tester Kit

What the Kit Covers

The AI3801 bundles three instruments from Apera's 60 Series Premium line into a single kit: the PH60 pocket pH tester, the EC60 conductivity/TDS/salinity tester, and the ORP60 redox tester. Each meter is a standalone, self-contained unit rated IP67 — fully waterproof and dustproof — so they float if dropped in a reservoir and hold up in a wet grow environment without babying.

The PH60 reads pH from -2.00 to 16.00 with ±0.01 accuracy and auto-recognizes five buffer types (1.68, 4.00, 7.00, 10.01, 12.45) for 1–3 point calibration. The EC60 switches one-tap between EC, TDS, and salinity with a customizable TDS conversion factor (0.40–1.00) to match your preferred reporting standard. The ORP60 covers -1000 to +1000 mV at 1 mV resolution, calibrated against the included 222 mV standard solution. All three share the same dual-display LCD format with three-color backlighting: blue for measurement mode, green for calibration mode, and red for out-of-range warnings.

Built for Commercial Cultivation Use

Dialing in fertigation starts with accurate, consistent water data. pH drift of even 0.2–0.3 units locks out micronutrients and compounds deficiency issues over a crop cycle. EC accuracy determines whether the plant is actually receiving the nutrient concentration your recipe calls for. ORP is increasingly relevant for facilities running UV or ozone sanitation on recirculating water, or anyone tracking oxidation status in reservoirs.

The 60 Series testers are built around Apera's proprietary lithium glass pH membrane (forged from rare earth materials) and platinum black conductivity sensor — sensor technology that gives you repeatable, stable readings across a wide measurement range with minimal maintenance between calibrations. Auto Temperature Compensation on all three meters covers 0–50°C, so readings stay accurate whether you're pulling from a chilled reservoir or measuring run-off in a hot flowering room.

Replaceable probes on every meter in this kit are a real operational advantage in a commercial setting. When a probe degrades, you swap the probe — not the meter body — keeping downtime and replacement cost low across a multi-site or multi-room operation.

Probe Technology and Calibration

The PH60's replaceable pH probe (PH60-E) uses Apera's lithium-based glass membrane, which provides faster electrode response and enhanced stability compared to standard sodium glass probes — important when you're testing dozens of fertigation checks per day. The EC60 uses Apera's Brush-Resistant Platinum Black (BPB) sensor, which minimizes electrode polarization and extends measuring range without the degradation typical of stainless-steel EC sensors.

The ORP60's platinum ORP probe is field-replaceable and calibrated using the 222 mV standard solution included in the kit. Stable-value recognition with optional auto-hold is present on all three meters, confirmed by a smiley-face indicator on the LCD — you know you're recording a settled reading, not catching a value mid-drift.

Calibration solutions for all three parameters are included in premixed, ready-to-use form. The pH kit includes 4.00 and 7.00 buffers plus 3M KCl storage solution. The EC kit includes conductivity calibration solution. The ORP kit includes the 222 mV standard and KCl soaking solution. All three meters run on AAA batteries with auto power-off at 8 minutes of inactivity and a low-battery warning indicator.

Kit Contents and Operational Fit

Each meter in the AI3801 kit ships as a complete, ready-to-use package: meter body, parameter-specific replaceable probe, premixed calibration solutions, calibration bottles, AAA batteries, a lanyard, and a portable carrying case. Nothing extra to source before first use.

For cultivation operations, the three-tester configuration covers the full measurement stack without the complexity of a benchtop meter or the compromise of a single combination probe — you have a dedicated, calibrated instrument for each parameter. That matters in a QA workflow: if one meter needs recalibration mid-shift, the other two remain in service. The IP67 rating and floating body mean accidental drops in a reservoir or drain line don't end the instrument's life.

Apera backs all three meters with a 2-year manufacturer's warranty on the instrument body and a 6-month warranty on each probe. Replacement probes for all three units are available as individual SKUs, keeping long-term cost of ownership predictable across a facility's testing program.
