Message InquiryDigital Dissolved Oxygen Sensor
Technical Features:
● Digital dissolved oxygen Sensor with RS485 output, which directly converts analog signals into digital signals
● Data is stored inside the Sensor, such as important parameters like zero point and slope.
● No need to calibrate the Sensor; it’s plug-and-play and easy to use.
● No transmitter is required; the Sensor outputs a digital signal that can be directly connected to a computer.
● The Sensor’s digital output can be directly converted into WIFI or GPRS signals for wireless transmission.
● Data can be transmitted both over short and long distances, with stable and reliable measurement values.
● Measurement range: 0 ppm to saturation, 0.1% to 200%, 0–20 mg/L
● Temperature range: 0–130°C, pressure range: 0.4 MPa
● Overall dimensions: Φ12×120, Φ25×165, or other sizes
