ZenTest Smart Pocket pH/Conductivity/TDS/Salinity/Resistivity Tester Kit

What It Is

The Apera ZenTest PC60-Z (SKU AI3719) is a multi-parameter pocket tester built around Bluetooth 5.0 connectivity and the free ZenTest mobile app. It measures pH (−2.00 to 16.00), conductivity (0–200,000 µS/cm), TDS (0–10,000 ppm), salinity (ppt), resistivity, and temperature in a single IP67-rated waterproof body. ORP measurement is also supported using the separately available ORP60-DA probe, making the platform expandable without replacing the base unit.

The PC60-Z ships as a complete kit: tester unit, PC60-DE replaceable combo probe, calibration solutions (pH 4.00, pH 7.00, 1413 µS/cm, 12.88 mS/cm), calibration bottles, storage solution, four AAA batteries, a lanyard, and a hard carrying case — everything needed to be operational at the first sample pull.

Who It's Built For

Commercial cannabis and hemp cultivation runs on tight water chemistry windows. Feed EC, runoff pH, and source-water TDS are checked multiple times a day across reservoirs, fertigation lines, and individual drain-to-waste collection points. A tester that can only log to memory — or one that requires manual transcription — creates documentation gaps that compound during an audit or compliance inspection.

The PC60-Z fits operations that need accurate, portable water quality data with a repeatable calibration record and a shareable log. Whether you're managing a single facility or overseeing multiple cultivation sites, the ZenTest app's cloud-based data management lets lead growers and compliance staff access measurement history without being physically on the floor. The IP67 body holds up to humidity, nutrient concentrates, and the occasional drop without compromising accuracy.

Key Features

The upgraded PC60-DE combo probe uses Apera's proprietary lithium-glass membrane with a double-junction reference system on the pH side — the double junction significantly reduces clogging risk when measuring nutrient-dense or organic-heavy solutions. The platinum black conductivity cell delivers ±1% F.S. accuracy across 0–200,000 µS/cm with minimal maintenance between grows. Both sensors are field-replaceable, so there's no reason to retire the meter when a probe reaches end of life.

ZenTest app connectivity via Bluetooth 5.0 enables real-time measurement display, step-by-step calibration guidance, automatic calibration reminders, and four display modes (simple, dial, graph, table). Cloud backup runs automatically on both manual and auto-logged readings. The app also supports asset tagging — measurements can be linked to specific tanks, benches, or zones — and data can be exported and shared directly from your device. The tester functions fully as a standalone unit without a phone connected, with up to approximately 500 hours of runtime on four AAA batteries.

How It Fits a Cultivation Build

In a licensed cultivation facility, the PC60-Z covers the full range of routine water chemistry checks: incoming source water (RO rejection rate, baseline TDS), reservoir feed (EC and pH targeting), mid-canopy sampling, and drain-to-waste runoff analysis. The wide EC range — 0 to 200,000 µS/cm — means the same probe handles both dilute source water and concentrated stock solutions without range-switching.

For multi-site operators or facilities with separate veg, propagation, and flower rooms, the ZenTest app's multi-meter management allows multiple PC60-Z units to be monitored from one interface and compared directly. Calibration records stored in the cloud provide an auditable history tied to each tester's serial identity — a cleaner paper trail than hand-logged notebooks if a state inspector asks to verify your instrument calibration records. The replaceable probe design keeps consumable cost predictable and avoids the all-or-nothing replacement cycle of fixed-probe testers.
