Trace Oxygen Analyser – Model 3190 Series

The Model 3190 is a microprocessor-based trace oxygen analyser for real-time measurement of trace amounts of oxygen in inert gases, or in a wide variety of gas mixtures. It features simple operation, fast response and a compact, rugged construction. Typical applications of the Model 3190 are monitoring nitrogen generators and inert gas blanketing applications.

• High resolution, accurate readings of oxygen content from 0-10 ppm through 0-25 %. Large, bright, light-emitting-diode meter readout
• Simple pushbutton controls
• Nylon cell holder
• Advanced micro-fuel cell, for trace analysis, has a six (6) months warranty and expected lifetime
• Unaffected by oxidisable gases
• Fast response and recovery time
• Microprocessor based electronics: 8-bit CMOS microprocessor with on-board RAM and 16 kB ROM
• Two user selectable ranges (from 0-10 ppm through 0-9,999 ppm) allow best match to users’ process and equipment
• Air-calibration range for convenient spanning at 20.9 %
• Operator can select Autoranging, which allows the analyser to automatically select the proper preset range for a given measurement, or he can lock the analyser onto a single range
