Phree Flow Electrodes
 
The pHoenix pHree-flow combination pH electrode incorporates a unique reference design that replaces the conventional porous ceramic junctions with a retractable spring-loaded sleeve. The pHree-flow is virtually clog-free, resulting in a longer life and more accurate and stable measurement. Simply press down on the cap to flush and renew the junction. Release pressure on the cap to retract the junction back into position. 

pHree flow electrodes are also available with Red Rod technology.
