Lab-grade pH accuracy built for high-temp beverage QC — beer, wine, kombucha, juice, and more.
The Apera PH850-BR (AI5533) is a portable pH meter purpose-built for professional beverage quality control. Equipped with the Swiss LabSen® 213 Glass 3-in-1 pH/Temperature Electrode, it delivers ±0.01 pH accuracy across a full 0–14 range and handles samples at temperatures up to 212°F without waiting for them to cool.
The Apera PH850-BR is a field-portable pH meter from Apera Instruments' Value Series, sold under SKU AI5533. It ships as a complete kit configured specifically for beverage-making environments — beer, wine, kombucha, juice, coffee, and other aqueous beverage matrices where pH directly governs flavor stability, fermentation trajectory, and batch-to-batch consistency.
The unit centers on Apera's Swiss LabSen® 213 Glass 3-in-1 pH/Temperature Electrode. Unlike conventional glass-bulb probes, the LabSen 213 uses an S-type hemispherical glass membrane that is reported to be approximately 10 times stronger than traditional glass membranes, delivering fully stabilized readings in 15 to 30 seconds. The electrode's patented pH/temperature combination structure places the temperature sensor in close thermal proximity to the pH glass, increasing temperature response time by 40% compared to a conventional isolated thermistor — which means faster ATC and more stable final readings.
This meter is a practical fit for licensed cannabis and hemp operators running post-harvest or value-added beverage programs — tinctures, infused kombucha, botanical extracts, or any aqueous formulation where pH is a recorded process parameter. It is equally suited to any commercial production environment conducting incoming QC on water or nutrient solutions where a rugged, accurate portable meter is preferred over a benchtop-only instrument.
The AI5533 is particularly useful in production environments where samples may still be warm. The LabSen 213 electrode handles sample temperatures up to 212°F, so operators do not need to cool samples before measurement — a meaningful time saver in active production workflows. The IP57 waterproof rating and soft silicone grip cover mean the unit can take the environment of a processing floor without a dedicated lab setup.
Calibration runs 1–3 points with automatic recognition of standard buffer values at 1.68, 4.00, 7.00, 10.01, and 12.45. After the second and third calibration points, the meter displays the electrode slope, giving the operator a direct indicator of electrode condition without guesswork. The self-diagnosis function flags out-of-range measurements, incorrect calibrations, and electrode invalidation in real time.
The LabSen 213 electrode uses Apera's proprietary blue gel inner solution, which does not flow, eliminating air bubbles inside the membrane — a common source of drift with liquid-filled reference systems. The reference system is a long-life architecture built from a glass tube, AgCl, and a silver reference wire; the tube is cotton-packed to prevent AgCl/electrolyte reaction under temperature changes, extending electrode service life.
Additional intelligent functions include auto temperature compensation (ATC), auto power-off, auto-lock on stable reading, and adjustable parameter settings. The large white backlit LCD is readable in dim processing areas. A foldable stand converts the handheld into a benchtop configuration. The unit is powered by AA batteries and is CE and RoHS compliant.
For commercial cannabis or hemp operators building out post-harvest processing or beverage manufacturing lines, pH monitoring is a recurring process step — not a one-time calibration event. A purpose-configured beverage meter like the PH850-BR eliminates the need to cross-reference general-purpose meters against beverage-specific conditions. The electrode is pre-matched to the meter and shipped kit-ready with buffers, so onboarding time is minimal.
The AI5533 sits in the Apera Value Series, positioned between basic pen testers and data-logging advanced meters. It covers the operational range that most commercial beverage QC programs require: reliable accuracy, high-temp sample compatibility, rugged build for floor use, and enough intelligent diagnostics to confirm electrode integrity without a dedicated lab technician. For operators who need data logging and USB output, Apera's PH8500-BR step-up model covers that tier.

Yes. The LabSen 213 electrode handles sample temperatures up to 212°F (100°C), so you can measure wort, hot kombucha batches, or other warm liquids directly without waiting for them to cool. Automatic temperature compensation adjusts the reading in real time.
The meter supports 1, 2, or 3-point auto-calibration. It automatically recognizes standard buffer solutions at pH 1.68, 4.00, 7.00, 10.01, and 12.45. After the second and third point, the display shows the electrode slope so you can assess electrode condition at a glance.
The self-diagnosis function flags electrode invalidation on the display. Additionally, the electrode slope value (shown after multi-point calibration) trends lower as the electrode ages — a significant drop from the initial baseline is a practical indicator that replacement is needed. Apera recommends replacing the electrode after approximately one year of regular use for best accuracy.
Yes. The PH850-BR includes a foldable stand that holds the meter upright on a flat surface, allowing it to function as a benchtop instrument when you need both hands free during sampling or titration steps.
Yes. The LabSen 213 connects via a standard BNC connector and is sold separately as a replacement. The electrode is compatible with other Apera meters that use BNC/RCA connectors, including the PH850, PH910, PH700, and PH8500 platforms. It is not guaranteed to be compatible with third-party meters due to thermistor differences.
