Sensorex SDA-7001 Replaceable Salt Bridge for SD7000 Series pH and ORP Sensors

Overview

When chemicals from challenging applications get inside the sensor reference, chemical reactions can create insoluble salts. These salts clog the reference junction and interrupt the electrical circuit, leading to drifting measurements. Fortunately, our differential pH and ORP sensors can be maintained with the SDS replaceable reference junctions (salt bridges). Simply remove the old salt bridge and insert a new one to restore normal performance to a clogged sensor. Replaceable reference junction for extending the lifetime of SD7000, SD7420, SD7500 sensors Direct-fit compatibility for several popular Hach & Water Analytics models One year limited warranty with the Sensorex Guarantee *Hach is a registered trademark of Danaher.
