SKU606589


Simple, accurate pH measurement in sensors designed for minimal maintenance in sampling, profiling, and long-term monitoring applications.

This sensor must be installed into a 6-Series sonde to function. Does not function on its own.

  • Overview

    YSI pH and pH/ORP sensors have been carefully designed to perform under all ionic strength conditions, from seawater with a conductivity of 53,000 μS/cm, to "average" freshwater lakes and rivers with conductivities of 200 to 1500 μS/cm, to pure mountain streams with conductivities as low as 15 μS/cm, which has historically been the most difficult medium with respect to accuracy, quick response to pH changes, and minimal flow dependence.

    6589FR Fast Response pH Sensor:
    Amplified sensor provides fast response and increased stability over standard pH sensors, despite the wear and tear of your instrument.

    Benefits:

    • Faster response time in sampling and profiling applications
    • Maintains fast response time in Low Ionic Strength (LIS) and cold waters
    • Maintains fast response time throughout life of sensor
    • Stable readings and like-new performance in instruments with aging or contaminated connectors

    Sensor is available for use on the following sondes:

    • 600XL & 600XLM
    • 600DW & 6920DW
    • 6820 V2 & 6920 V2
