Overview

The Model 907 is a Portable Oxygen and CO2 analyzer, used for research or package testing.

The 907 is a portable headspace analyzer for measurement of O2 and CO2 levels in gas flushed MAP packages (such as coffee or meat products). Alternately, the 907 can be used for portable O2 and CO2 measurements for research applications (such as cell culture incubators).
It weighs only 2 lbs, and comes with a nylon protective case and internal rechargeable battery pack. It can be easily operated without removal from the shoulder strap case.

ULTRA FAST

The Model 907 incorporates the latest fast response O2 and CO2 sensors, which allows results to be obtained in 5-7 seconds for rapid spot checks.

EASY SAMPLING METHOD

Our standard sample probe assembly for food package testing connects to the front panel of the Model 907.
The sample probe is tipped with a particulate filter and luer fit syringe needle with side-port holes to prevent plugging.
Additionally, the probe tip can be fitted with a Moisture Guard moisture filter, which is very useful for testing samples with moisture present.
Also, the Model 907 can be equipped with a tube/metal probe assembly, useful for testing enclosures or processes where a probe must be inserted into the area to be measured. When the internal pump is activated, sample is drawn through the probe and tubing and then to the sensors.

USER FRIENDLY, ACCESSIBLE CONTROLS

The Model 907, when carried in the shoulder strap case, has all of the commonly accessed
controls on the top of the unit for routine operation. Additional calibration and timing control adjusters are on the bottom of the analyzer, easily accessed by removing it from the carry case.

ABOUT THE SENSORS

The solid-state infrared CO2 sensor utilizes dual wavelength technology for maximum stability.
It has no moving parts, no consumables, and is housed in a compact optical cell. The sensor responds to CO2 only.
The electrochemical O2 sensor life is typically 3-4 years, unlike other analyzers with an electrochemical sensor that last 1-2 years. When required, replacement is easy and inexpensive.
Both sensors are unaffected by high levels of background gases such as nitrogen.

MICROPROCESSOR/ELECTRONICS

Micro-processor based electronics provide sensor signal processing, battery charging, pump timing and on/off control for high accuracy and reliability with minimal component use and reduced size and cost.
The Model 907 CO2 sensor combines cutting edge 32-bit digital signal processing with the solid reliability, compact size and state of the art microprocessor technology that makes this
full-featured CO2 measurement system less complex and more robust than other instrumentation.
The Model 907 uses a long-life, fast response heavy duty electrochemical O2 sensor, with an expected lifetime of 3-4 years. Other electrochemical O2 sensors have an expected life of 1-2 years.
The expected life of the CO2 sensor is theoretically unlimited, as it contains no moving parts or consumables.

WARRANTY STATEMENT

The Model 907 is backed up with a two year warranty, twice the industry standard.
