Item # 340 Series, Portable Analyzer for Oxygen and Hydrogen


The Nova 340 Series Portable Analyzer has been designed for the dueal measurement of O2 and H2 in furnace atmoshpere gases. A built-in sample pump draws in a sample of atmosphere gas where it is detected for oxygen by a long-life oxygen sensor. At the same time, H2 is detected by a long-life thermal conductivity cell.

The model 341 is a dual range O2 version that can be switched between the standard range (0-25.0%) and a lower range (0-2.0%) usingthe same sensor. For applications requiring a PPM O2 measurement, a special low range version is available (Model 340L). The models 340 & 341 have rechargeable battery operation, a flow meter, filter, sample hose and dual digital readouts. A recharger is included. Recorder outputs of 4-20 mA or 0-1V are optional.
