All Hanna DO probes are shipped dry. To hydrate the probe and prepare
it for use proceed as follows:
1. Remove the black & red plastic cap. This cap is used for shipping
purposes only and can be thrown away.
2. Insert the supplied O-ring in the membrane
(see figure).
3. Rinse the supplied membrane (

) with electrolyte
while shaking it gently. Refill with clean electrolyte. Gently tap
the membrane over a surface to ensure that no air bubbles
remain trapped. To avoid damaging the membrane, do not
touch it with your fingers.
4. With the sensor facing down screw the cap clockwise to the end
of the threads. Some electrolyte will overflow.
