A desiccant cartridge is located inside the ProSample controller to absorb moisture and prevent corrosion. Over time the desiccant will become saturated with moisture and should be replaced. Monitor the desiccant color through the clear plastic window. The color will change from blue to pink when the desiccant is saturated.
This replacement desiccant cartridge is designed for use with all ProSample models.
Please see the ProSample Ordering Guide if ordering a complete system, or contact us if you have any questions.
