The WTW QSC Kit supports the Quality Sensor Control (QSC) function on MultiLine® IDS meters. It performs a one-time factory-referenced quality check of an IDS pH electrode, then continuously grades sensor condition so you can see at a glance when a probe should be replaced.

A must-have for GLP/GMP-style pH quality assurance with the Multi 3510 / 3620 / 3630 IDS. Part number 109830.
