Hi Iluke

Yes the fluke one is the same as the H4 but if you allow me a suggestion, I prefer the H5, it has many more characteristics, the option of the flow lab software, a bigger graphic touch screen, fully configurable at the unit, several gas standards, and the option of some automatic test routines for Bellavista, Phillips etc.

And the last new they added the option of Anesthesia agent measurement

Hope this help

Take care keep healthy
