Polestar’s non-invasive pH sensors will have you quickly up and monitoring accurately
Glass-Free, Pre-Calibrated Sensing Technology
Polestar’s optical pH sensing films uses ratiometric fluorescent detection that automatically corrects for signal loss due to photobleaching, providing stable, accurate, and reliable measurements of pH over the life of the sensing film. Films are delivered pre-calibrated with responses to pH that are independent of the solution temperature. The fluorescent sensing approach is glass-free and eliminates the need for reference electrodes and the easily clogged liquid junctions that limit the operation lifetime of traditional pH electrodes.
Sensing films are available for two ranges of pH
•pH Low – 3.0 to 6.5
•pH Mid – 6.0 to 9.0
Films can be stored dry between uses, are USP Class VI certified and compatible with gamma sterilization.
