The HI769828-2 is a galvanic dissolved oxygen membrane sensor for use with the HI769828 probe. The sensor body is constructed of durable PVC material and contains an easily replaceable membrane cap design. The membranes are constructed of polytetrafluoroethylene (PTFE) and each cap screws easily onto the sensor. The HI769828-2 sensor contains a silver cathode and zinc anode. The sensor module is color coded for easy installation and integration with the probe.
  • Easily Replaceable Membrane Caps
  • No Warm-Up Time

Easily Replaceable Membrane Caps

The polytetrafluoroethylene (PTFE) membranes use a screw-on cap design for simple electrolyte filling and easy placement on the sensor.

Galvanic Design

The sensor’s galvanic dissolved oxygen design requires no conditioning or warm up time. The sensor is always ready to go allowing for measurements to be taken right away.

Color Coded Sensor

Sensors are color coded to match sensor ports on the probe for quick, field-replaceable, screw-type, connection and identification.
