Key Features
-
Memosens Digital Technology: Supports Memosens 2.0 digital sensors for pH, ORP, conductivity, and dissolved oxygen. Enables pre-calibration in the lab and plug-and-play sensor replacement, eliminating on-site calibration.
-
Hazardous Area Compliance: Certified for use in ATEX Zone 1 and Class I Division 1 hazardous locations, making it suitable for chemical, oil & gas, and pharmaceutical applications.
-
Modular & Expandable: The base platform allows for later expansion with additional I/O modules (e.g., relays, extra analog outputs) without replacing the entire unit.
-
Predictive Diagnostics: Built-in Heartbeat Technology monitors sensor health and provides predictive maintenance alerts for cleaning or calibration.
Applications
-
Chemical & Petrochemical: pH and conductivity monitoring in reactors, neutralization tanks, and effluent streams in explosive atmospheres.
-
Pharmaceutical & Biotech: USP <645> water purity compliance and WFI (Water for Injection) monitoring with digital sensor traceability.
-
Water & Wastewater: Continuous monitoring of pH, ORP, and conductivity in inlet, treatment, and discharge stages.
-
Power & Energy: Boiler feedwater and cooling water analysis in power plants and utilities.
