Potting the Probe Head Connections

Warnings.

Potting materials are toxic – use suitable safety precautions

Read the manufacturer's instructions carefully before preparing the potting material.

Notes.

The probe head connections must be potted immediately on completion, to prevent ingress of moisture.

Check all connections before potting – see Section 4.

Do not overfill or allow the potting material to come into contact with the 'O' ring or groove.
