Benchtop pH Meter Kit

What It Is

The Apera PH800 (SKU AI521) is a dedicated benchtop pH and temperature meter designed for consistent, repeatable measurement of aqueous nutrient solutions. It ships as a complete kit: the PH800 meter body, the 201T-F combination pH/temperature electrode, pH 4.00, 7.00, and 10.01 ready-to-use calibration buffers, USB cable, and electrode holder. Everything needed to start measuring is in the box.

The meter's core measurement engine delivers ±0.01 pH accuracy across a −2.00 to 19.99 pH range with selectable 0.1 or 0.01 pH resolution. Automatic temperature compensation runs continuously from 0 to 100 °C, driven by the integrated temperature sensor in the 201T-F electrode — so readings adjust in real time as solution temperature changes, without manual intervention. The large backlit LCD displays pH and temperature simultaneously alongside stable-reading and calibration-complete status icons.

Who It's For

Any licensed cannabis or hemp cultivation operation running a fertigation or hand-watering program needs reliable pH data at the bench — not at the reservoir edge with a pocket pen. The PH800 is suited for head growers, cultivation managers, and QA teams who are doing regular nutrient solution checks, running tissue culture, verifying runoff pH across multiple cultivars, or operating under state-mandated quality documentation requirements.

The GLP (Good Laboratory Practice) data management system stores up to 500 measurement sets with timestamps and exports via USB, making it straightforward to pull records for internal compliance reviews or state inspections. If your operation is ISO-adjacent, moving toward third-party certification, or simply needs a paper trail for nutrient program QA, having an auditable log on a benchtop unit changes how you document your grow.

Key Features

Calibration is 1 to 3 point automatic, with on-screen guidance and self-diagnosis. The meter auto-recognizes five NIST-traceable standard buffers: pH 1.68, 4.00, 7.00, 10.01, and 12.45 — no manual entry. A calibration reminder function prompts staff when recalibration is due, and the last calibration record is always accessible for review.

Electrode health is surfaced between calibrations via real-time slope display — a direct indicator of whether your 201T-F electrode is still performing within spec or needs replacement. The 201T-F itself is built on Apera's proprietary lithium-glass membrane for signal stability, with a dual ceramic-fiber junction that reduces clogging compared to single-junction designs. A detachable sensor shield protects the glass bulb during storage and transport.

The standard BNC connector means the PH800 isn't locked to a single electrode. Apera's full LabSen specialty electrode lineup — covering low-ionic-strength samples, TRIS buffers, viscous solutions, and more — connects directly via the same port. ORP measurement mode is also available when a compatible ORP electrode is connected (sold separately).

Data Management and PC Integration

The PH800's PC-link software runs in-browser (Chrome, Edge, or Firefox) with no installation required — plug in via USB and retrieve all 500 stored measurements at once. The software generates real-time charts and supports one-click export to CSV or PDF reports that include measurement values, calibration date, electrode slope and offset, meter model, and serial number. That's a complete audit-ready record without needing to transcribe anything manually.

For multi-station grow operations, the flexible electrode holder on the PH800 bench body accommodates up to three electrodes, supporting setups where the same meter serves multiple solution lines in sequence. The meter socket includes seal protection to maintain integrity in humid cultivation environments. CE certified. Instrument warranty: 3 years. Electrode warranty: 6 months.
