The connection to our gas flow analyzers changes depending on the testing you are about to do.

If you are testing breath parameters or bi-directional flow the connection should be a Y connector on the flow inlet side and a calibrated test lung on the flow exhaust side. Always use an antibacterial filter on the inlet side to elongate the life and accuracy of your gas flow analyzer.

When testing uni-directional flow or concentration measurements the DUT simply needs to be connected to the flow inlet side using an antibacterial filter.

Saving results is easy on any of these units. From any screen there is a blue box in the bottom right called “Save”. Press on this button and you are able to save your results as data, a graph, a recording or under a new Test ID. These results can then be recalled from the onboard memory under “Menus” and “Memory”.

VAPOR does not have a battery and is powered by the VT900A. If VAPOR was operated constantly, VT900A and VAPOR would have a combined battery life of at least 5 hours.

All of these products have an 8-hour battery life allowing you to test all day, on-the-go.

Firmware is field-upgradeable and downloadable from our site at the gas flow software page. The link will state whether a calibration is required. Your device will always be upgraded to the most recent firmware version if your device is sent to a Fluke service center.

VT900 lacks the connector on the rear panel that provides power and communication to the VAPOR Anesthesia Tester. Only the VT900A has this connector.

The VAPOR Anesthesia Tester is an accessory to the VT900A that allows for preventive maintenance / efficacy testing of vaporizers. VAPOR can test the concentration of 5 major anesthetic agents, CO2 and N2O.

From a technical standpoint, there is no difference between the VT900 and the VT900A. The only difference is that a connector was added at the rear panel to allow for power and communication to the VAPOR Anesthesia Tester.

The features that differentiate the VT900A and VT650 are the ability to measure ultra-low flow and ultra-low pressure, the ability to use an external TTL trigger input and improved oxygen sensor accuracy and lifetime (1% accuracy and a 2-year lifetime vs. 2% accuracy and a 1-year lifetime).
