Value Series Benchtop pH Meter Kit with TestBench

What It Is

The Apera PH950 is a benchtop-class pH meter positioned in Apera's Value Series — meaning it delivers lab-grade accuracy without the cost of a research instrument. The AI5620 kit bundles the PH950 meter body with Apera's TestBench (model 606), the Swiss-made LabSen® 211 glass combination pH electrode, and the MP500 temperature probe. You get a self-contained measurement station out of the box.

The meter reads across the full 0.00–14.00 pH range at ±0.01 pH accuracy with a selectable 0.01 or 0.1 pH resolution. Automatic temperature compensation (ATC) runs from 0–100°C (32–212°F), covering any realistic nutrient solution or media slurry temperature you'll encounter in a production facility. The large backlit LCD displays pH and temperature simultaneously, along with electrode slope, calibration status, and a stability indicator — no guessing when the reading has settled.

Who It's For

Any licensed cannabis or hemp operation running recirculating hydro, coco, rockwool, or living soil where pH discipline is non-negotiable. A pocket pen tester gets grabbed off a shelf and used inconsistently across a team — a benchtop station stays at the mixing station, gets calibrated on a schedule, and produces a traceable result every time.

The PH950 is the right tool for head growers and cultivation techs who are mixing nutrients daily, adjusting fertigation recipes across multiple zones, or managing a propagation room where a half-unit pH swing kills an entire clone tray. It is also appropriate as a reference instrument for operations that use inline or handheld meters on the floor and need a reliable bench unit to verify and re-zero those tools against a controlled calibration standard.

Key Features

The Apera TestBench (606) is what separates this kit from a bare-meter purchase. It consolidates a flexible electrode holder, an intelligent magnetic stirrer with stepless speed control, and buffer solution organizers into one compact workstation. Calibration goes faster and cleaner when your buffer bottles are staged in fixed positions and your electrode is held at a consistent depth — the TestBench eliminates the ad-hoc setup that leads to dirty or contaminated calibration solutions.

Calibration itself is 1–3 point automatic, with on-screen instruction prompts guiding the tech through each step. The meter auto-recognizes five standard buffer values (1.68, 4.00, 7.00, 10.01, 12.45) and supports USA, NIST, and China buffer series plus user-defined standards. Self-diagnosis runs automatically and displays electrode slope so you can catch a degrading probe before it produces bad readings. Onboard manual data logging stores 100 measurement groups with timestamp. USB connectivity and the included PCLink-950 software allow data export to PC for SOP documentation or state record-keeping. The multi-language OS (English, German, Spanish, Mandarin) is a practical feature in multi-shift facilities with mixed-language teams.

How It Fits a Commercial Build

In a purpose-built cultivation facility, the mix room or dosing station is the right home for the PH950. Mount or position the TestBench on a dedicated counter near your nutrient concentrate storage. At the start of each shift, a tech calibrates with fresh buffer solution from the staged organizers, runs a quick self-diagnosis to confirm electrode slope is within spec, and the station is ready for the day's mixing and verification pulls.

The onboard data log — and USB export to PC — gives you a lightweight audit trail without a LIMS system. For state compliance programs that require cultivation records, logged pH readings with timestamps are a defensible part of your SOPs. The LabSen 211 combination electrode is a field-replaceable consumable; the 3-year instrument warranty on the meter body means the station doesn't become a capital expense every season — only the probe refreshes as needed.
