YSI’s 4220W is a digital, pressure-resistant sensor designed for long-term, low-maintenance oxidation-reduction potential (ORP) monitoring in water applications. Built for durability and precision, this sensor delivers continuous, stable ORP measurements and includes an integrated temperature sensor to enhance accuracy in dynamic environments.

  • Overview

    Fully compatible with YSI’s Water Monitoring Panel controlled by the IQ SensorNet system, the 4220W offers digital signal conversion and real-time data delivery—empowering operators to optimize process control and obtain regulatory compliance assurance with confidence.

    Pressure-Resistant & Field-Ready:
    Engineered for high-pressure environments (up to 145 PSI), the 4220W is ideal for demanding applications.

    Integrated Temperature Compensation:
    Built-in temperature sensor ensures precise ORP measurements across varying thermal conditions, reducing drift and improving response time in dynamic systems.

    Digital Smart Sensor:
    When paired with IQ SensorNet controllers, the 4220W unlocks advanced capabilities such as:

    • Plug-and-play digital integration
    • Multi-parameter compatibility
    • Data logging and trend analysis
    • Communications via Modbus RTU, Profibus, and Ethernet/IP
    • Can store up to 10 calibrations

    Low Maintenance Operation:
    Designed with a lifetime gel electrolyte and robust plastic body, this sensor minimizes maintenance needs, extending service intervals and reducing operational costs.

    Common Applications:

    • Municipal drinking water
    • Industrial cooling towers
    • Environmental monitoring
    • Aquaculture

    Model:

    • 4220W: Digital ORP sensor with integrated temperature sensor and pressure-resistant design for use with IQ SensorNet controllers.
