Question
Which IntelliCAL™ pH probes have a double junction?
Summary
Double junctions on IntelliCAL™ pH probes.
Answer
Most IntelliCAL™ pH probes use a double junction design. The PHC101xx, PHC201xx, PHC301xx, and PHC281xx probes all use a double junction.The PHC101xx and PHC281xx both have an open junction, while the PHC201xx and PHC301xx probes have a ceramic pin junction. Although a probe may have an open or ceramic pin junction, it can still use the double junction design.
