10.1 Device type
The
gas-lab
Q1 measuring system is a flameless measuring instrument for
determining the quality of natural gases using an infrared absorption-based
measuring method. It consists of a heavy-duty housing, in which the actual
sensor unit is accommodated, and of an evaluation computer, which must be
operated in a non-hazardous environment. The system operates continuously
and fast and can be used for billing or controlling applications.
