EC Electrode
• Probes process signal directly for noise free measurements
• Auto sensor recognition
• Store calibration specifi c data from the last calibration
• Are built with materials suitable for use in chemical analysis
• Have integrated temperature measurement
• Incorporate a 3 mm jack termination
• Unique serial ID in every probe for traceability
