How to clean the Probe
Soak the lower half of the probe in 100 mL inline probe cleaning solution for 15-30 minutes. If the
surface is not entirely clean, continue to soak the probe for an additional time until clean. Rinse the
probe with distilled water. Pyxis Lab Inline Probe Cleaning Solution can be purchased at our online
Estore/Catalog at https://pyxis-lab.com/product/st-500-probe-cleaning-kit/
