Low Maintenance (Non-refillable) pH Electrodes

Low maintenance pH electrodes are easy to use and require minimal maintenance. Since the reference chamber is sealed, you never need to replace fill solution or clean and rinse the reference chamber. You may choose from many styles such as

AquaPro, Green electrodes, double junction or silver chloride electrodes to suit your measurement needs. AquaPro low maintenance pH electrodes offer open junctions that do not clog. Choose between chemical resistant glass bodies or durable epoxy bodies. All AquaPro electrodes are TRIS compatible.

Green electrodes contain no hazardous substances such as mercury or lead and are ROHS compliant. Double junction electrodes are TRIS compatible and you do not have to worry about interfering substances. Silver chloride electrodes offer low maintenance as well as reliable measurements for everyday use.
