SKU606579


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 6600 V2-4 sonde with a wiper 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.

    6579 Hemispherical pH Sensor:
    The YSI 6579 Hemisphere pH Sensor is a longer-length probe with hemispherical glass bulb. This extended length allows it to be wiped by 6600V2-4 sonde brush, and it's hemispherical shape protects most of the bulb. 6569 pH/ORP Hemispherical Probe also available.

    Benefits: 

    • Greater length allows it to be wiped by 6600V2-4 sonde brush. 
    • Hemispherical shape protects most of the bulb. 

    Limitations: 

    • Unguarded. May occasionally produce jumpy readings.

    Sensor is available for use on the following sonde:

    • 6600 V2-4 with wiper/brush only
