The Apera Instruments ORP60 Premium Pocket ORP Meter is a professional-grade solution for fast and reliable oxidation-reduction potential (ORP) testing in pools, spas, hydroponics systems, aquaculture, drinking water, and water treatment.

With a measurement range of ±1000 mV and ±0.2% F.S. accuracy, the ORP60 is built for performance and durability. It comes with a replaceable platinum ORP electrode, a 3-colour backlit LCD, and manual calibration using the included 222 mV standard solution. Its intelligent display guides you through readings (blue), calibration (green), and alert modes (red).

Waterproof to IP67 and floatable, it’s ideal for field and laboratory use alike. The ORP60 is backed by a 2-year warranty (meter) and 6 months (probe) for total peace of mind. Powered by 4 AAA batteries, it offers up to 2000 hours of continuous operation.

Packaged in a durable carry case with calibration solution, lanyard, and user guide, this is your complete portable ORP test kit — ideal for serious growers, technicians, and water quality professionals.
