These are available in two versions, model oa-11: it has a working range of 0-30% oxygen; model oa-12 : it can be used from 0 to 100% oxygen levels. 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.Its applications area includes: air separation plants; cylinder gas quality; fruit storage; food packing machines; medical monitoring; purge gas monitoring; landfill gas; and nitrogen purged soldering systems.
