Bluetooth-connected ORP and temperature measurement with cloud data logging — in a pocket-sized, IP67-rated body.
The Apera ORP60-Z (AI3717) is a Bluetooth-enabled, IP67-rated pocket ORP and temperature tester powered by the free ZenTest mobile app. It delivers ±1000 mV ORP measurement at ±0.2% F.S. accuracy with cloud-based data logging — built for professional water quality monitoring in commercial cultivation, hydroponics, water treatment, and beyond.
The Apera ORP60-Z is a pocket-sized ORP (Oxidation-Reduction Potential) and temperature tester from Apera's ZenTest 60-Z Smart Series. It pairs wirelessly to the free ZenTest mobile app via Bluetooth 5.0, giving operators a smartphone-guided testing workflow in place of manual LCD-only operation. The meter measures ORP across a ±1000 mV range with 1 mV resolution and ±0.2% F.S. accuracy, plus temperature from 0–50°C (32–122°F) at ±0.5°C accuracy.
The IP67-rated enclosure is fully submersible and dust-sealed — rated for both bench and field use without babying the instrument. The kit ships complete: ORP tester body, platinum ORP probe with built-in temperature sensor, 222 mV calibration standard solution, calibration bottle, KCl storage solution, AAA batteries, lanyard, and a portable carrying case. Everything needed to start measuring is in the box.
Any licensed cannabis or hemp cultivation operation running recirculating or drain-to-waste hydroponic systems needs ORP visibility — particularly facilities using ozone injection, UV sterilization, or oxidizing sanitizers to manage water pathogen loads. ORP gives you a direct electrochemical read on oxidative strength in your reservoir or irrigation lines, which pH and EC alone cannot tell you.
The ORP60-Z is also suited to post-harvest and extraction operations managing sanitation water, quality-assurance labs requiring traceable measurement records, and head growers who need data they can share with ownership or compliance teams without transcribing notebook entries. The cloud-based data log in the ZenTest app means readings are timestamped, stored, and shareable via email — directly from the phone.
The ZenTest app (iOS and Android, free) drives the meter's most useful functionality: step-by-step guided calibration workflows, self-diagnosis alerts when probe performance degrades, customizable alarm thresholds, and auto-hold with a 5–20 second stable-reading window. The app also supports multiple display modes — simple, dial, graph, and table — depending on whether you need a quick spot-check or a detailed review of trending data across a measurement session.
The platinum ORP probe is a field-replaceable module. When the probe ages out, you swap the probe — not the whole meter. The 3-color backlit LCD (blue for measurement, green for calibration, red for alarm) remains fully functional without a smartphone, so the meter works as a conventional standalone tester when the app isn't needed. Auto power-off activates after 8 minutes of inactivity. Power comes from 4× AAA batteries included in the kit.
In a commercial facility, ORP monitoring typically sits alongside pH and EC as a third data point for irrigation water quality. While pH and EC are checked on every feed cycle, ORP becomes critical any time sanitizers or oxidizers are in the system — ozone dosing, hydrogen peroxide applications, or chlorine-based line flushes. An accurate, portable ORP meter lets your head grower or IPM lead verify effective oxidative concentration at the point of application rather than relying on dosing rates alone.
The cloud data logging feature is particularly useful for multi-site operators or facilities that document water quality for compliance or SOP auditing purposes. Measurements are tagged with calibration info and can be shared via email from the app — creating a lightweight, paperless chain of custody for every test. The asset-tagging capability in the ZenTest app allows readings to be assigned to specific tanks, reservoirs, or batch identifiers for organized tracking across the grow cycle.

Yes. The meter operates as a conventional standalone tester when not connected to a smartphone. The 3-color backlit LCD displays ORP and temperature readings directly on the meter. Bluetooth and the ZenTest app unlock guided workflows, cloud logging, alarm settings, and data sharing — but are not required for basic measurement.
The platinum ORP probe is a field-replaceable module — twist off the probe ring, unplug the aged probe, plug in the new one, and re-secure the ring. Apera warranties the probe for 6 months. Replacement probes (ORP60-DE) are available separately through HSC. This design means you extend the life of the meter body rather than replacing the full unit when the probe ages.
ORP (Oxidation-Reduction Potential) measures the electrochemical oxidizing or reducing strength of your water in millivolts. In cultivation, it's most relevant when oxidizing sanitizers are present — ozone, hydrogen peroxide, or chlorine-based products. ORP gives you a direct read on whether the sanitizer concentration is within an effective range, which dosing rates alone can't confirm. It's also used for general water quality trending in recirculating systems.
When connected via Bluetooth, the ZenTest app automatically stores measurement and calibration data in a cloud-based system. Data can be tagged to specific assets (tanks, reservoirs, batch IDs) and shared via email directly from the app, complete with calibration info attached to each record. Data is retained in the cloud — not just locally on your device — so records persist across phones or team members.
The ORP60-Z is positioned as a professional-grade instrument. The ±0.2% F.S. accuracy, IP67-rated enclosure, replaceable platinum probe, calibration workflow with self-diagnosis, and cloud-based data logging with email sharing all indicate a tool intended for professional water quality monitoring — not entry-level consumer use. It is used in hydroponics, aquaculture, water treatment, pool/spa, and laboratory settings.
