Easily Replaceable Membrane Caps

The pretensioned HDPE (High Density Polyethylene) membranes use a screw-on cap design for simple electrolyte filling and easy placement on the sensor.

No Warm-Up Time

The sensor’s galvanic design requires no conditioning time for the electrodes, allowing you to take measurements 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.
