 Technical feature

·

 Polarographic and galvanic oxygen sensor with stable performance and reliable measurement.

·

Stable zero point and small drift of the sensor.

·

Quick response of sensor (reaching up to 98% measure value<60 seconds).

·

With the measurement range from 2ppb to  20ppm and the compression resistance of 0.4Mpa.

·

With the temperature range :0~80.

·

With the flow rate of 0.02m/s.

  • Digital DO sensor

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

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

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

    · The measured value is stable and reliable.

    · measuring range: 0ppmsaturation, 0.1%200%. 

    · Temperature rang: 0130.

    · pressure range0.4MPa.

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

    · The thermistor is Pt100Pt10002.252K10K22K etc.
