How To Order:
1. Indicate series such as 1222.
2. Indicate range desired such as: 8, 12 or M200.
3. Specify “W/M” with model number for inches* of water, using water or inches* of mercury, using mercury. Specify “D” with model number for inches* of water using .826 sp. gr. red gage oil. Red gage oil is often preferred for readings in inches of water because of the longer scale and slower evaporation rate. This lessens the need for frequent re-zeroing and refilling. (If not otherwise indicated, “W/M” style manometers will be shipped.).
4. For Series 1223 only, state the connection option desired if other than standard type “a”. For example, 1223-12-D-“b” manometer is a Series 1223, range 12" w.c. (scale 6-0-6), using red gage oil with type “b” connections.

*Metric units are in millimeters.
