Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
Electrolyte must be added to the sensor before use. Refer to the steps that follow and Figure 1 .
1. Install the membrane on the sensor body by hand as far as it will go.
2. Use the syringe to add 5 mL of electrolyte to the sensor body. Make sure that there are no
impurities or bubbles in the electrolyte.
3. Gently push the electrode into the sensor body until there is resistance. Do not force the
electrode.
4. Install and tighten the holding nut by hand.
5. Install the gasket and filling screw to prevent electrolyte leakage or external contamination from
the sample. Carefully tighten the screw with a screwdriver without using excessive force.
