PH60-HF pH Meter Kit for HF-Containing and Strong Acidic Solutions

What It Is

The Apera PH60-HF is a purpose-built handheld pH meter kit designed for one specific problem: accurate pH measurement in solutions that destroy ordinary electrodes. It pairs the Apera PH60 meter body — IP67 waterproof, 3-point auto-calibrating, field-proven across industrial and scientific applications — with the Swiss LabSen 835 pH/temperature electrode, which incorporates a specialized HF-resistant membrane that standard glass electrodes cannot survive.

The LabSen 835 electrode is rated for up to 1,000 HF measurements (measurement time under one minute, HF concentration below 0.1 mol/L or 2,000 ppm). It also handles general strong acidic solutions and performs reliably in standard aqueous solutions, making this kit adaptable beyond single-application use.

Everything ships ready to use: pre-mixed calibration buffer solutions, soaking solution, the Apera CalPod Solution Organizer to keep calibration materials organized in the field, AAA batteries, lanyard, and a rugged carrying case. No separate purchases needed to get started.

Who Needs This Meter

Any cultivation or processing operation working with nutrient concentrates, acidic pH-down solutions, cleaning compounds, or specialized chemical inputs at high concentration levels will eventually run into the limitations of a standard pH probe. At strong acid concentrations, ordinary Ag/AgCl reference systems drift, junctions clog, and glass membranes erode — leading to bad reads that compromise fertigation accuracy or cleaning verification.

The PH60-HF is the right tool for: QC testing of concentrated acid inputs before dilution, verifying pH in acidic cleaning or sanitation solutions, nutrient reservoir monitoring when working with high-concentration formulations, and any application where a standard probe has given inconsistent or shortened-life performance. It is equally suited to lab environments, grow facility control rooms, and field-use scenarios where portability and waterproofing are non-negotiable.

Licensed cannabis and hemp operators running coco, rockwool, or deep water culture at scale often push pH-down solutions at concentrations that shorten conventional probe life. This kit is built for that environment.

Key Features — Meter and Electrode

Meter body: The PH60 runs ±0.01 pH and ±0.5°C accuracy across a -2.00 to 16.00 pH range with 0–50°C automatic temperature compensation (ATC). Calibration is up to 3-point auto (pH 4.00 / 7.00 / 10.01) with automatic recognition of five buffer types (1.68, 4.00, 7.00, 10.01, 12.45). The three-color backlit LCD — blue for measurement, green for calibration, red for out-of-range alerts — gives unambiguous mode indication. Stable-value recognition auto-locks readings with a visual indicator, removing guesswork from manual hold. Battery life reaches up to 2,000 hours continuous (without backlight), with auto power-off after 8 minutes of inactivity. IP67 rated — submersible and floats.

LabSen 835 electrode: The HF-resistant membrane is manufactured in Switzerland and is engineered to minimize the acidic error that compromises standard glass electrodes in low-pH, high-acid environments. The reference system uses a Silver Ion Trap architecture with open junction and polymer electrolyte — this design eliminates the junction clogging that kills standard Ag/AgCl probes and maintains stable reference potential over time. The glass membrane is rated at 10× the strength of traditional glass membranes. A built-in temperature sensor feeds the ATC system directly, ensuring compensation accuracy at the electrode tip.

The LabSen 835 electrode is also compatible with other Apera meters fitted with 8-pin connectors (PH400, PC400, PH400S, PC400S, SX751, SX736, and others), giving operators flexibility to use the electrode across a bench or handheld meter inventory.

How It Fits a Commercial Operation

Consistency in pH measurement is a compliance and crop-quality issue. Inaccurate readings — caused by a degraded probe, a clogged junction, or the wrong electrode type for the solution chemistry — introduce variability into every fertigation event, every cleaning verification, and every QC log. The PH60-HF removes the electrode-compatibility variable from strong-acid applications entirely.

The CalPod Solution Organizer included in the kit keeps calibration buffers and soaking solution accessible and properly labeled, which matters in a busy facility where multiple staff may be using instruments across shifts. The rugged carrying case protects the full kit during transport between rooms or facilities.

Probe replacement is straightforward — the LabSen 835 is a field-replaceable electrode, so when the electrode reaches end-of-service life (up to 1,000 HF measurements), the meter body is preserved. Apera's warranty covers the instrument for 2 years and the probe for 6 months from delivery.
