AMI has provided yet another breakthrough for portable trace oxygen analysis. The patented cellblock technology and abundance of standard electronics features have resulted in a state-of-the-art package.

The Model 1000RS utilizes our innovative patented cellblock technology that eliminates the need for the traditional, individual sample system components that are typically pieced together using tubing, compression fittings, valves and flow meters.

Our approach begins with a compact solid metallic block, which undergoes a complex machining process, followed with corrosion-resistant nickel plating. The block contains a series of internal drilled gas passages, replacing external tubing and compression fittings.

The process includes sophisticated machined ports that accommodate a fine metering valve, 4-way selector valve, an oxygen sensor and flow meter, keeping all components integral to the block.

The unique 4-way selector valve offers many distinct advantages:

• It opens or closes both the sample gas inlet and exhaust ports simultaneously with a simple 90° rotation.
• In the "OFF" position the sensor is completely sealed from the outside air (20.9% oxygen) during long distance travels between measurement sites, increasing sensor life and responsiveness.
• The "OFF" position also acts as a sample gas bypass, further protecting the sensor from exposure to high oxygen levels during the initial connection from the sample point to the analyzer.
• After making a simple gas connection and using the purge feature, simply rotate the selector valve 90° which opens both the "Sample Gas In" and "Exhaust" ports simultaneously, and watch how fast the Model 1000RS responds.
• No more confusing quick disconnect logic.

When the application requires, we can provide one of our patent-pending H2S resistant oxygen sensors (up to 500ppm H2S exposure for its warranted life) to meet your needs. This breakthrough sensor technology eliminates the need for maintenance intensive H2S scrubbers.

The 1000RS has been designed for intrinsically safe use in flammable gases and is equipped with numerous standard electronic features listed:

• State-of-the-art microprocessor based electronics.
• High-resolution single range LCD immediately reads from 0.00ppm to 25% without range changing delays or the need for manual adjustments.
• Data logger: logs data for 15 days at 1min intervals, 30 days at 2min intervals, etc.
• 0-1VDC analog output.
• 10 user-selectable analog output ranges: 0-10ppm, 0-50ppm, 0- 100ppm, 0-500ppm, 0-1000ppm, 0-0.500%, 0-1%, 0-5%, 0- 10% and an air calibration range of 0-25%
• Complete security feature: front panel settings will not respond to tampering if the security feature has been initiated via laptop computer.
• Rechargeable NiCad batteries: operates for 350 hours continuously.
• Low Battery indicator
• Built in trouble-shooting diagnostics
• Cal Factor - determines remaining O2 sensor life

The front panel sensor access makes sensor installation or replacement quick and easy. It also allows for a rapid, accurate calibration using ambient air (20.9%) if desired without the need for span gas. For those who wish to use certified span gas, simply connect the span gas to the sample gas port, briefly purge using the 4-way selector valve, rotate the selector valve 90° to the "Open" position; the reading will rapidly stabilize and you use the intuitive front panel interface to instantly adjust the reading.

No other portable trace O2 analyzer on the market compares in the areas of accuracy, reliability, response time, ease of use, desirable features, compact size and low cost.
