ORP readings are only as good as the electrode taking them, and a worn or lower-grade probe can quietly undermine your water quality monitoring. The Bluelab ORP Probe solves this with a platinum spiral electrode and ceramic diaphragm built for durability and precise readings, serving as a direct replacement probe for the Bluelab ORP Meter.
A double-junction design and standard BNC connector make it compatible with any meter that uses a BNC connection, not just the ORP Meter it's built to replace. The polycarbonate body houses a 12mm/0.47" × 122mm/4.8" shaft, giving it a rugged, purpose-built form factor for daily solution monitoring.
A 2-metre (6.6ft) cable, fully waterproof construction, and a storage cap containing KCl storage solution round out a probe built to hold up in demanding water quality environments — keeping your disinfection tracking accurate whenever a fresh probe is due.
Delivers precise, durable ORP readings for reliable monitoring.
Adds stability and long-term durability to every reading.
Compatible with any meter that uses a BNC connection.
