Kit contents & digital integration

• Kit includes RC1R5N analog ORP sensor, AD 1200 Digital Gateway, and 1 m digital extension cable.
• Digital signal allows transmission up to 1000 m (3280 ft) with Hach Gateway or sc100 controller.
• Built‑in platinum electrode provides stable, linear response across full ORP range.
• Excellent noise immunity eliminates interference in industrial environments.
• The HACH DRC1R5N kit converts analog sensors to digital for modern control systems.

Frequently asked questions (FAQ)

• What makes DRC1R5N different from DRC2K5N? The DRC1R5N kit includes the AD 1200 Gateway and extension cable, while DRC2K5N is a standalone digital sensor.
• Can I use this sensor without the Gateway? No, the RC1R5N is an analog sensor; the AD 1200 Gateway converts it to digital for Hach controllers.
• What is the maximum distance from the controller? You can place the sensor up to 1000 m from a Hach Digital Gateway or sc100 controller.
• Is temperature compensation included? No, this sensor has no built‑in temperature compensation; use optional conductors for external RTD.
• What flow rate can this sensor handle? The maximum recommended flow is 2 m/s to maintain measurement stability.
