Methods to Cleaning the SP-710B
A light deposit on quartz glass inside the conductivity cell can be cleaned by a Q-tip. Aged heavy deposi-
tion, especially iron oxide deposited, can be removed using a cleaning solution that is capable of removing
iron, such as the Pyxis Handheld Device Cleaning Solution Kit (P/N: SER-02) available from Pyxis online eS-
tore/Catalog

To clean the SP-710B pour cleaning solution into the main module sample cell for 10 minutes. Rinse the
sample cell with distilled water and use the Cleanliness Check (see the
Main Module Sample Cell Cleanli-
section) to confirm that the SP-710B is clean. Repeat the process as needed until the Cleanliness
Check shows
Clean

Storage
When the pH/ORP cell is not in use, fill the cell with 1 mL of Pyxis pH/ORP Storage Solution (P/N: 63900)
and ensure the pH/ORP cell seal is closed completely. The pH/ORP cell seal maintains a moist environment
for the electrodes. For vigorous field use, it is recommended to utilize a rubber-band to secure the pH/ORP
cell seal to prevent loss of pH/ORP Storage Solution.
Do not expose the SP-710B to an extreme high or low temperature condition such as leaving the SP-710B
inside an unattended automobile.

NOTE
*
Repeated extreme low and high temperature cycling will damage the pH elec-
trode.
