Included in delivery of the device:

•Brief instructions (Leporello)

•CD-ROM with detailed documentation

1)For oxygen application, add Order code E10.

2)Version 7MF4233-1DY... only up to max. span 200 mbar a (2.9 psi a)

3)When the manufacture’s certificate M (calibration certificate) has to be ordered for transmitters with diaphragm seals, it is recommended only to order this certificate exclusively with the diaphragm seals. The measuring accuracy of the total combination is certified here.
