Description |
|
Mercury manometer according to Ludwig-Cyon, with inclined tree-way cock. The small glass pipes are positioned securely in a thin iron frame ending in a steel case with plug screws, that empty and clean them easily. The cock is connected to the glass pipes on the one side and with the tube point, that leads to the end of the vessel, on the other side by grinded cone parts and fixed by a cap nut. The clamp nut may be screwed to the kymograph in different heights. The float consists of an ivory rod; its steel needle is let within a fine polished steel edge. |
