IP67-rated ORP monitoring with a replaceable platinum probe — built for daily cultivation use.
The Apera ORP60 (AI315) is a field-ready, IP67-waterproof pocket ORP tester with a ±1000 mV range, 1 mV/±0.2% F.S. accuracy, and a user-replaceable platinum probe — everything a licensed cultivation operation needs to monitor oxidation-reduction potential consistently across reservoirs, irrigation lines, and treatment systems.
The Apera ORP60 (SKU: AI315) is part of Apera's Premium 60 Series of pocket testers — a line engineered for accuracy and daily field durability. The ORP60 measures oxidation-reduction potential (redox) across a full ±1000 mV range with 1 mV resolution and ±0.2% F.S. accuracy, paired with a 0.5°C temperature accuracy and automatic temperature compensation (ATC) across 0–50°C.
The unit ships as a complete ready-to-use kit: the ORP60 meter, a 222 mV premixed calibration standard solution, a calibration bottle, KCl electrode storage solution, AAA batteries, a lanyard, and a premium portable carrying case. Nothing extra to source before you put it to work.
Any licensed cannabis or hemp cultivation operation monitoring water quality at scale needs reliable ORP data. ORP readings tell you whether your irrigation water, nutrient reservoir, or treatment system is in the oxidizing or reducing range — critical for assessing disinfection efficacy (chlorine, ozone, hydrogen peroxide treatments), reservoir sanitation, and overall water health before it touches your crop.
The ORP60 fits naturally into the workflow of head growers, cultivation technicians, and IPM managers who are pulling daily or shift-level readings from multiple zones. Its compact form factor, floatable IP67-rated body, and auto-stable reading detection make it fast and practical on a busy production floor where stopping to baby a fragile instrument isn't an option.
The replaceable platinum ORP probe is the most commercially relevant feature on this unit: when the electrode ages out, you swap the probe — not the entire meter. The platinum sensor is also cross-compatible with Apera's PH60, PH60S, and PH60F pH meters, so operations already running Apera pH testers can standardize probes across their bench.
The 180° viewing-angle backlit LCD uses three distinct backlight colors — blue for measurement mode, green for calibration mode, and red for warning/alarm — eliminating ambiguity about which mode you're in at a glance. Auto-recognition of stable values with an optional auto-hold function removes the guesswork of manual read timing. Battery life is rated at up to 2,000 hours of continuous operation (backlight off) from 4 × AAA cells, with a low-battery warning and an 8-minute auto power-off to protect runtime.
In a licensed cultivation facility, ORP sits alongside pH and EC as a core water chemistry data point. Growers running peroxide or ozone sanitation programs especially need accurate, repeatable ORP readings to verify treatment concentration without over- or under-dosing. The ORP60's manual calibration against the included 222 mV standard — with on-screen calibration confirmation — keeps readings traceable and auditable, which matters for facilities operating under state compliance frameworks.
The IP67 rating means the unit tolerates the wet, humid environments common to commercial grow rooms and fertigation bays without requiring special handling. Because the probe is field-replaceable and Apera backs the meter with a 2-year manufacturer's warranty (6 months on the probe), total cost of ownership stays predictable.

You replace only the probe. The Apera ORP60-E replacement probe is sold separately and installs without tools. The platinum ORP probe is also cross-compatible with Apera's PH60, PH60S, and PH60F meters, so if you're running multiple Apera testers you can standardize on one probe SKU.
The ORP60 calibrates against a 222 mV standard solution. A premixed, ready-to-use 222 mV calibration solution and calibration bottle are included in the kit. Calibration is performed manually with temperature compensation applied, and the meter confirms successful calibration on-screen.
Yes. The ORP60 carries an IP67 rating, meaning it is fully dust-proof and can withstand submersion. It is also buoyant — if dropped in a reservoir or drain channel, it floats. The auto power-off engages after 8 minutes of inactivity to protect battery life in high-humidity environments.
The ORP60 covers −1000 to +1000 mV, which captures the full range relevant to cultivation water: most treated irrigation water and sanitation programs (peroxide, ozone, chlorine) operate in the +200 to +700 mV range. The ±1000 mV range and 1 mV resolution give you margin on both ends.
