The following features are standard on the Model 3110:

• Display: A 2-line 20 character alphanumeric LCD on the front panel displays data and operational information through various screens. The contrast is adjustable for various lighting conditions.
• Four-Button User Interface: Operation is performed using the four front panel mounted buttons. These buttons are used to enter data, select items and move through operational screens that appear on the display.
• Universal AC Charge Adapter: The batteries can be recharged without removing them from the instrument. The charger operates over the range of 100-240 VAC.
• LEDs: Two front panel-mounted LEDs are used to indicate low battery condition and when the battery is recharging.
• Contrast Control: This feature allows the user to easily adjust the contrast of the display for optimum viewing under different lighting conditions. The adjustment is made using a front panel control dial.
• Auto-ranging: The user is able to specify two analytical ranges for scaling of the output in Auto- Ranging mode. The Model 3110 will automatically switch between these ranges depending on the oxygen level.
• Percent of Range Voltage Output: A 0-1 VDC output is available that represents the percentage of the current analysis range.
• Data Logger: The optional built-in data logging feature allows the user to specify the time interval between data recording sets. The date, time, and oxygen concentration readings are stored in internal RAM at the user specified interval. The data set can be downloaded using the instrument’s 9-pin serial interface.
• Real-time Clock: This feature allows the Model 3110 to date and time stamp the data set recorded on the data logger. It uses a 24 hour clock.
• Quick Disconnect Fittings: Dual self-sealing quick disconnect fittings are installed for easy sample connections.

The Teledyne Electronic Technologies/Analytical Instruments (TET/AI) Series 320BRC and 320P Portable Oxygen Detectors meet or exceed all of the requirements of the Commonwealth of Europe (CE) for Radio Frequency Interference and Electromagnetic Interference (RFI/EMI) protection. Models 320A and 320B are not complying with the requirements of the Commonwealth of Europe. The analyzers are designed to continuously measure the percentage of oxygen in a gas atmosphere. The measurement is specific for oxygen and no special standardization or zero gases are required. A letter designation, after the model number, indicates a specific version as specified by the customer at time of purchase.

• Micro-Fuel Cell
• Multiple Sampling Modes
• External Output Capability
• Accessory Flow-through Adapter

The Model 3190 is a microprocessor- based trace oxygen analyzer 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 oxidizable 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 analyzer to automatically select the proper preset range for a given measurement, or he can lock the analyzer onto a single range.
