Filling the Sensor

You need the following materials for this task:
• pH or Na
• appropriate sensor fill solution kit containing a fill solution vial and a cylinder that
contains a needle
• lint-free tissue or cloth
BIOHAZARD:
Refer to Appendix A, Protecting Yourself from Biohazards for recommended
