4.2 Assemble the sensor

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
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.

4.3 Install the sensor in the process

Keep the sensor in a vertical position with the membrane down during mounting and removal. Do not shake the
sensor so that oxygen does not contaminate the electrolyte.
Refer to the steps that follow and
1. Connect the sensor cable to the sensor and tighten the connector by hand. Do not turn the cable
