Sensor replacement cautions:
CAUTION: The sensor contains a caustic or acid liquid. If there is any sign of a liquid in the cell
compartment, do not allow it to come into contact with your skin. If it does, immediately flush
the affected area with water for a period of at least 15 minutes. Refer to the Material Safety
Data Sheet provided
Dispose of leaking or used sensors in accordance with local regulations.
Sensors usually contain lead which is toxic, and should generally not be
thrown into ordinary trash. Refer to the MSDS to learn about potential
hazards and corrective actions in case of any accident.

2. Unscrew the cell cap.
3. Remove the old sensor.
4. Open the bag containing the new sensor.
5. Push the new sensor into the block using its handle as shown above.
