    Introduction The Teledyne Analytical Instruments (TAI) Model 326 series (Models 326, 327, and 328) analyzers use a unique Micro-Fuel Cell to measure the concentration of oxygen in a gas stream. The analyzer can be housed in a compact equipment case, a 19-inch rack mount unit, an explosion-proof bulkhead-mounted enclosure, or separately from the panel-mounted control unit.

After sample flow has been re-initiated, and the proper scale of analysis selected, the alarm point can be precisely reset by simply re-dialing the set point.
