Neptune Systems Lab Grade Double Junction ORP Probe

Overview

The Neptune Systems Double Junction ORP Probe is built for longevity, reliability, and accuracy. Unlike traditional lab-grade probes, the double junction design isolates the reference gel from proteins and organics that can clog and contaminate the sensor. This results in longer probe life, fewer calibrations, and more stable readings—making it an ideal replacement or upgrade for your aquarium monitoring system.

Key Features

• Double Junction Design – Prevents contamination of the sensing element for longer-lasting performance.

• Reliable Readings – Provides stable and accurate ORP measurements with reduced drift.

• Universal Compatibility – Works with Neptune Apex and any monitor or controller using a BNC-style connector.

• Durable Construction – Lab-grade probe designed to withstand continuous use in aquarium environments.

• Low Maintenance – Requires calibration less frequently than standard probes.
