Bluelab ORP Meter

Monitor ORP to track solution quality

Monitor Oxidative-Reduction Potential (ORP) to track solution quality, sanitising performance, and sanitation throughout the growth cycle. ORP measurements help prevent risks such as contamination, biofouling, equipment malfunction, and low crop yields, while ensuring compliance with water quality certification standards. A higher ORP value indicates a stronger oxidative environment, meaning more effective sanitisation against bacteria, algae, and pathogens. It is a key indicator for ensuring clean and healthy water in hydroponic and irrigation systems. The device features a compact, handheld design for convenient use and a clear, easy-to-read backlit display.

This meter is suitable for professional cultivators and hobbyist growers using hydroponic or irrigation systems. It offers dual compatibility, allowing for optional use with a Bluelab pH probe for comprehensive monitoring. The device has an automatic shut-off function. The replaceable Bluelab ORP probe features a BNC connection, and ORP probe calibration is not required. The probe's cap is filled with KCl to maintain hydration, and a 2m cable provides reach for measuring in difficult locations.
