We offers high performance low cost Analysers for measuring oxygen levels from pure oxygen down to fractional percentage levels. These analysers are based on electrochemical cell sensors. Model OA-12 can be used from 0-100% oxygen. Digital readout of concentration and dual alarms are standard features. Each alarm channel is provided with a set of changeover relay contacts. The alarm set points can be set and displayed from the front panel. A needle valve regulator and a flow indicator enable the user to regulate sample gas flow from the front panel.
