- Two hoses with couplings.
- Two needles incl. ball valves.
Flow and pressure can be displayed in various units, which you can choose from in the menu.
The PFM 100 can communicate with you in one of 10 possible languages.
Please note that the pressure unit must not be exposed to subzero temperatures. The pressure unit must at all times be stored at temperatures above 0° C.
