Description
The RKI Instruments RI-257 is a portable gas analyzer built for measuring gas concentration in the field or the plant rather than from a fixed location. Weighing about 3.8 kg, it can be carried to the sampling point, and its digital display gives a direct numeric reading. The measurement is designed to show negligible interference from other gases, which helps when the sample contains background components. Target gas and range depend on the factory configuration, so users should confirm these against their application before ordering.
