Bluetooth-connected pocket pH with ±0.01 accuracy, cloud logging, and a replaceable double-junction probe.
The Apera PH60-Z (AI3711) is a Bluetooth 5.0 smart pocket pH tester powered by the free ZenTest mobile app — delivering ±0.01 pH accuracy, automatic temperature compensation from 0–50°C, and cloud-based data logging in a field-ready, waterproof form factor. Comes complete with a double-junction probe, NIST-traceable calibration buffers, 3M KCL storage solution, and a hard carrying case.
The Apera PH60-Z is a next-generation smart pocket pH tester in the 60-Z series. It pairs a precision glass-bulb pH electrode with Bluetooth 5.0 connectivity to the free ZenTest mobile app — available on iOS and Android — giving cultivation staff real-time measurement control, guided calibration, and automated data logging from a phone or tablet rather than a clipboard.
The kit ships with a double-junction pH probe (PH60-DE), which offers improved resistance to contamination compared to a single-junction design — an important distinction for nutrient-heavy feed water, coco leachate, or reservoir samples where reference electrode fouling can degrade reading stability over time. The tester measures across the full –2.00 to 16.00 pH range with 0.01 pH resolution and automatic temperature compensation from 0 to 50°C.
In a licensed grow, pH isn't a set-it-and-forget-it check — it's a multiple-times-daily measurement across fertigation lines, reservoir tanks, runoff, and foliar prep buckets. A tester that sits on a shelf because it's slow to stabilize, hard to calibrate, or lacks any data trail is a liability. The PH60-Z addresses each of those friction points.
Auto-stable value recognition tells the operator exactly when a reading has locked — no more pulling the probe too early and logging a false number. Up to 3-point auto calibration with recognition of five standard buffer values (1.68, 4.00, 7.00, 10.01, 12.45) means calibration takes under two minutes with the included pH 4.00 and 7.00 NIST-traceable buffers. The ZenTest app stores calibration records alongside every measurement in cloud-based unlimited data storage, giving an IPM auditor or compliance team a time-stamped log without manual entry.
The ZenTest app is the operational layer that separates the PH60-Z from a standard pocket meter. Step-by-step smart guides walk operators through calibration and measurement procedures, which matters in environments with rotating staff or new hires unfamiliar with electrode care. Readings can be tagged to specific assets — tanks, batches, zones — keeping data organized by grow room or irrigation line rather than buried in a single undifferentiated log.
Measurement results, calibration data, and operator notes can be shared instantly from the phone via email or the cloud-based data management system. The tester supports flexible display modes inside the app for routine testing, detailed review, or demonstration. Critically, the PH60-Z operates as a conventional standalone tester even when not connected to a phone — hybrid functionality means a dead phone battery does not stop the measurement.
Every AI3711 kit includes: PH60-Z tester with the PH60-DE double-junction glass bulb pH probe installed, pre-mixed pH 4.00 and pH 7.00 NIST-traceable calibration buffer solutions, calibration bottles, 3M KCL electrode storage solution, AAA batteries, a lanyard, and a hard-shell portable carrying case — everything needed for immediate deployment without a separate consumables order.
The PH60 tester body is probe-compatible with the full Apera 60-series electrode lineup. Alternative probe types include the PH60S-E spear probe for soft-solid or media sampling (runoff from coco slabs, for instance), the PH60F-E flat-surface probe, and the ORP60-E ORP electrode — all sold separately. Apera recommends replacing the pH probe every 1–2 years depending on use frequency, sample chemistry, and maintenance practices. Replacement probes are available through HSC.

A double-junction reference electrode has a second barrier between the reference electrolyte and the sample solution. This significantly slows contamination of the reference junction by heavy ions or complex organic compounds in nutrient-rich feed water, high-TDS reservoir solutions, or media runoff — environments typical in commercial cannabis cultivation. It extends probe service life and maintains measurement stability in samples that would quickly foul a standard single-junction probe.
Yes. The PH60-Z is a hybrid design — it functions as a fully conventional standalone tester with its onboard display and controls when not connected to the ZenTest app. Bluetooth and app connectivity add cloud logging, data sharing, guided calibration, and asset tagging, but they are not required for basic measurement in the field.
The PH60-Z supports 1 to 3 point auto calibration and automatically recognizes five standard pH buffer values: 1.68, 4.00, 7.00, 10.01, and 12.45. For most cultivation applications — feed water and runoff measurements ranging pH 5.5–7.0 — a 2-point calibration using pH 4.00 and 7.00 (both included in the kit) is sufficient and recommended. The first calibration point must always be pH 7.00.
Yes. The ZenTest app includes cloud-based unlimited data storage that automatically backs up measurement and calibration records. Data can be tagged to specific assets (tanks, batches, rooms) and shared directly from the app via email or cloud access — providing a time-stamped digital log that supports state-level compliance documentation and internal quality records without manual transcription.
Apera recommends replacing the pH probe every 1–2 years, depending on use frequency, sample chemistry, and maintenance. Signs of a degraded probe include slow response time, difficulty calibrating, or erratic readings. Compatible replacement types for the PH60 tester body include the PH60-E (standard glass bulb), PH60-DE (double-junction, as included), PH60S-E (spear, for media/solids), PH60F-E (flat surface), and ORP60-E (ORP).
