Polilyte Plus pH Sensors - Traditional
Polilyte Plus traditional sensors provide a standard mV output that allows connection to traditional transmitters and controllers. They have a maintenance-free design to withstand demanding industrial applications in chemical, petrochemical, process water, and wastewater treatment applications. Common reference problems such as clogging are eliminated with the two Single Pore junctions. The Polilyte sensors show good measurement accuracy in highly alkaline solutions as well as in samples with low conductivity. Additionally, the Everef-L reference cartridge ensures a long lifetime. A stabilized sensor signal and an extended sensor diagnosis thanks to the integrated Liquid Earth in the VP are further features of the Polilyte Plus.

What solution should I store my pH or ORP probe in?
Hamilton recommends storing pH and ORP probes wet in either Hamilton Storage Solution (Ref 238931) or in 3M KCl solution. Click to see the pH/ ORP Sensor Storage and Regeneration Knowledgebase for more information. -
Where can I find documentation and certificates for my sensors?
Paper copies sensor information such as manuals, declarations of quality, and material certificates ship with the product. Hamilton also has several website resources to find related information. Click on the FAQ to learn more. -
How much torque is needed to install a sensor with PG13.5 threads?
Sensors with PG13.5 threads rely on the o-ring to seal against process pressure. Finger-tight (approximately 2 Newton Meter or 18 inch-lb) should be sufficient to install the sensor without leakage. Additional tightening beyond this can deform the o-ring or strip the threads.
