  • Digital pH sensor

    · It can convert analog signals to digital signals ,and it is a predictive digital pH sensor.

    · Data stored in the sensor interface,such as zero point,slope etc.

    · the date can close transmission but also long distance transmission .

    · The measured value is stable and reliable.

    · Don't accept the influence of the surrounding environment ,such as temperature, electromagnetic field etc.

    · pH range:0-14; zero point: E0=7pH; Temperature rang: 0-110.

    · pressure range0.6MPa.

    · The external dimension of the sensor isΦ12×120,225 or other size.
