Home Gas Analyzer Indonesia Model 340 Portable O2 & H2 Analyzer (NOVA)
Model 340 Portable O2 & H2 Analyzer (NOVA)

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%) using the 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, flow meter, filter, sample hose, and dual digital readouts. A recharger is included. Recorder outputs of 4-20mA or 0-1V are optional.

Analysis of oxygen/hydrogen (O2/H2) in exothermic furnace atmospheres for copper, brass, or steel annealing, neutral heating, sintering, glass metal beds, or oxide coating of steel.
