This could be used in other operation such as Varnishing facility, Coating facility, Semiconductor industry, Gas indication panels, Mechanical engineering, N2/O2 generators, Burner controller, Laboratories and research. Plus, it is supported with an analogue output that is no that costly. Also, different versions are available such as model having integrated 31/2-digit LCD display, having 8 digit counter and model without additional tools. It uses a direct stream protocol which measure 5 LN/min up to 7500 LN/min.
