Reminders when choose models
1. Please pay attention that the media should be compatible with the contacted parts; please inform the
density of the media (except water);
2. Two kinds of cable are optional, polyurethane and polyethylene. The default is polyethylene. Polyurethane
cable is more flexible and endurable; it can be selected due to the requirement;
3. When the product is used in thunder storm area, we suggest the user to use protection device to protect
the product and power grounding reliably;
4. For special requirement, please feel free to contact us
