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 (HI 76409A/P) 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.
