Lab-grade pH in dirty liquids — Swiss electrode, Bluetooth data logging, ±0.01 pH accuracy.
The Apera PH60Z-WW (AI3737) pairs the ZenTest PH60Z smart meter body with the Swiss LabSen 335 ATC pH/temp electrode — purpose-built for wastewater, nutrient suspensions, coco runoff, emulsions, and other solids-containing solutions that routinely clog standard junction electrodes. Bluetooth-connected to the ZenTest Mobile App for cloud-based data logging with timestamps, geo-location, notes, and photos.
The PH60Z-WW is a purpose-configured smart pH meter kit from Apera Instruments, combining the ZenTest PH60Z handheld meter body with the LabSen 335 — a Swiss-engineered pH/temperature combination electrode designed specifically for dirty, complex, or solids-containing liquids. The meter body delivers a −2.00 to 16.00 pH range with 0.01 pH resolution and ±0.01 pH accuracy, backed by automatic temperature compensation (ATC) from 0 to 50°C and a temperature measurement range of 0 to 100°C at ±0.5°C accuracy.
The meter is IP67 waterproof, runs on 4× AAA batteries with up to 2,000 hours of operating life, and auto-powers off after 8 minutes of inactivity. A 3-color LCD (blue = measuring, green = calibration, red = alarm) displays pH and temperature simultaneously. The unit operates as a standalone tester or connects via Bluetooth to the ZenTest Mobile App (iOS, Android, Mac) for full smart functionality — data logging, cloud backup, geo-tagged records, and step-by-step calibration guidance.
The kit ships complete: LabSen 335 electrode pre-installed, ready-to-use calibration buffer solutions (pH 4.00, 7.00, 10.01), soaking solution, Apera CalPod Solution Organizer, and a rugged carrying case. Nothing else to source before first use.
Standard pH electrodes use a porous ceramic junction saturated with liquid electrolyte. In nutrient-dense runoff, coco slurry, organic teas, emulsions, or any solution carrying particulates, that junction clogs — readings drift, stabilize slowly, or stop responding altogether. The LabSen 335 solves this with an open junction combined with a polymer electrolyte, maintaining full sample contact and eliminating the clogging mechanism that defeats conventional electrodes in these applications.
The electrode's Long-Life Reference System is engineered to maintain reference potential stability over time, outperforming standard Ag/AgCl systems and extending service life. A specially formulated blue gel inner electrolyte fills the sensor body, eliminating trapped air bubbles that cause erratic, jumping readings — a common failure mode in field-use electrodes. The built-in NTC 30kΩ temperature sensor enables automatic temperature compensation directly at the probe tip. The electrode is non-refillable by design, requiring no electrolyte top-offs between uses.
All sensor materials and core technology are sourced from Switzerland under Apera's LabSen platform. The LabSen 335 is also compatible with other Apera meter bodies using 8-pin connectors (PH400, PC400, PH400S, SX751, SX736, and others), making it a flexible replacement or upgrade electrode for existing Apera bench setups.
Connect the PH60Z meter body to the ZenTest Mobile App over Bluetooth on iOS, Android, or Mac. The app assumes full control of calibration — providing step-by-step guidance through up to 3-point auto calibration with automatic recognition of five NIST-standard buffer values (1.68, 4.00, 7.00, 10.01, 12.45). No manual calculation, no guessing at buffer recognition.
All measurement data logs automatically to the cloud with timestamps and geo-location — useful for compliance documentation across multiple grow rooms or facilities. Operators can attach photos and notes to each reading, then share records directly from the app. Manual and auto-logger modes are both supported, and cloud backup protects data against device loss. The meter still functions as a conventional standalone tester with on-body button controls when a smartphone connection isn't available or needed.
In licensed cannabis and hemp production, pH management is non-negotiable — but the media and fertigation inputs used in commercial cultivation are exactly the problem cases that standard pH electrodes struggle with. Coco coir runoff carries fine organic fiber. Compost teas, fermented plant extracts, and organic nutrient suspensions contain particulates and emulsified organics. Even recirculating reservoir water in high-EC systems can carry enough dissolved solids to compromise a standard ceramic junction over time.
The PH60Z-WW handles all of these without the drift, slow response, or junction-clogging failures that make cheap testers unreliable and require frequent replacements. For operations running regular runoff checks across multiple benches, fermentation monitoring, or water treatment staging, the Bluetooth + cloud logging workflow reduces transcription error and creates a defensible audit trail. The rugged IP67 meter body tolerates the wet, chemical-heavy conditions standard to any production grow floor.
The 2-year instrument warranty and 6-month electrode warranty apply to the kit as shipped. Replacement LabSen 335 electrodes are available separately for kit continuity without replacing the meter body.

Standard ceramic-junction electrodes clog when the junction pores become blocked by particles, organic matter, or protein from dirty sample matrices — a common problem with coco runoff, nutrient suspensions, compost teas, and emulsions. The LabSen 335 uses an open junction combined with a polymer electrolyte, which maintains full liquid contact with the sample while preventing clog formation. This keeps readings accurate and response times fast across these challenging media types.
Yes. The meter body operates as a fully functional standalone pH tester. Single-button controls on the meter handle power, measurement hold, calibration mode entry, and basic settings. Bluetooth and the ZenTest App add cloud logging, geo-tagged records, step-by-step calibration guidance, and data sharing — but the core measurement capability does not require a phone connection.
The PH60Z supports up to 3-point automatic calibration with automatic buffer recognition. It recognizes five standard buffer values: pH 1.68, 4.00, 7.00, 10.01, and 12.45. The kit ships with ready-to-use pH 4.00, 7.00, and 10.01 buffer solutions. For most cultivation applications — where working pH falls between 5.5 and 7.0 — a 2-point calibration at 4.00 and 7.00 is standard practice.
Yes. The LabSen 335 is a separately available replacement electrode. It is compatible with Apera pocket testers that have an 8-pin socket (PH60, PH60-Z series) and with Apera bench/portable meters using 8-pin connectors including the PH400, PC400, PH400S, PC400S, SX751, and SX736. If you already own one of those meter bodies, the LabSen 335 can be purchased as a standalone probe upgrade for dirty-liquid applications.
Each measurement logged through the ZenTest App is automatically tagged with a timestamp and geo-location. Operators can add free-text notes and attach photos to individual readings before the data is synced to cloud storage. Records can be shared directly from the app via email or export. The cloud backup means data persists even if the phone or meter is lost. Both manual logging (operator-triggered per reading) and automatic interval logging modes are supported.
