ORP Metre

The ORP Meter (Model TE/301) is an industrial-grade inline monitoring and control instrument engineered for continuous Oxidation-Reduction Potential (ORP) measurement. Designed to optimize chemical dosing in water treatment and sterilization processes, the TE/301 delivers real-time analytical accuracy to ensure proper disinfectant residual levels without over-chlorination or under-dosing.

Featuring a high-contrast digital LED display, intuitive calibration controls, and built-in controller relays, the TE/301 seamlessly integrates into automated chemical feed loops—providing instantaneous feedback for ozone, chlorine, and chlorine dioxide dosing systems.

Key Features & Operational Advantages

• Precision Real-Time Readout: High-sensitivity micro-processor circuitry provides accurate, continuous ORP readings ($\pm 1\text{ mV}$) across demanding water quality environments.

• Integrated Controller Functions: Equipped with programmable SPDT relay outputs to directly control automated chemical dosing pumps, solenoid valves, and external alarm systems based on user-defined setpoints.

• Compact Panel-Mount Design: Standard DIN panel enclosure engineered for space-saving, clean installation inside control cabinets and centralized system racks.

• Intuitive Calibration Protocol: Features simple two-point or one-touch buffer calibration to maintain measurement accuracy with minimal downtime.

• Robust Signal Stability: Built-in noise rejection and temperature compensation mechanisms protect against electrical interference common in industrial environments.
