The AII GPR-2900 Oxygen Analyzer is a general purpose oxygen analyzer with barometric pressure and temperature compensation, four measurement ranges, and two user configurable alarm contacts. All versions can be locked manually to a single range or auto-range. The analyzer also features a 4-20mA isolated signal output, 4-20mA or 1-5V DC range ID outputs, Delrin remote sensor housing with 1/8-inch tube fittings, AC or DC power, and a panel mount aluminum enclosure.
