The Model 3190 Trace Oxygen Analyzer is a microprocessor based analyzer offering high accuracy, easy use, and full features in a compact unit. In addition to providing the latest technology in a small footprint, these units are an unbeatable value.

Two ranges are standard on the 3190 at 0 - 100 and 0 - 1000 ppm with a 0-25% calibration range. Optional ranges are available. Two programmable alarms (one high and one low setpoint) satisfy most requirements.
