From environmental monitoring to developing new energy sources and chemicals for the new era, gas analysis systems are faced with needs and challenges that have changed dramatically over time. Responding to these new needs, HORIBA has developed the VA-3000, the versatile gas analyzer that's ready for the future. A single analyzer is now capable of measuring a wider selection of gas components utilizing many different types of sensor technology. Non-dispersive infrared (NDIR) modules are available to measure gases such as CO, CO₂, NO, N₂O, CH₄, SO₂ and others. A chemiluminescent sensor module may be included to measure NO or NOx with a standard converter. And four different types of sensor modules are available to measure O₂ - galvanic, paramagnetic, zirconium oxide or magnetopneumatic. Designed to be compact and lightweight, the VA-3000 may have up to three sensor modules installed in a single analyzer case. This unique feature means the VA-3000 can be used today for a broad range of applications including research and development or environmental pollution monitoring, where efficiency and space-saving are crucial.

Use to measure the concentration of many different gases
A single VA/VS-3000 analyzer is capable of simultaneously measuring multiple gas components such as CO, CO₂, O₂, NOx, SO₂, CH₄, N₂O and other gases. With the VS-3000 sampling system, the VA/VS-3000 will meet the needs of a diverse range of applications.


Many combinations of sensor modules are possible
Development of smaller sensor modules now makes it possible to install up to three sensor modules in a single unit. You can install three NDIR modules in a single case or substitute a chemiluminescent or oxygen module for any of the NDIR modules.

Wide selection of ranges and flexibility for many applications
The VA-3000 also features dynamic ranges up to 20x the base (first) range. And the dynamic range can be further expanded by installing multiple sensor modules for the same component gas in a single analyzer case. Now a single unit can perform measurements over a wide range from ppm to 100 percent concentrations. With our diversified lineup of modules, you can always choose the optimum range for your application.

High precision assured
The VA-3000 achieves repeatability of ±0.5% of F.S.R. (Full Scale Range), linearity of ±1.0% F.S.R., and drift of less than ±2.0% per week without requiring recalibration with a gas standard saving you money. For optimum precision, use the auto daily calibration feature, to virtually eliminate drift. Or specify the optional gas filled calibration cell that is used to routinely check and adjust the calibration of the NDIR modules without the need for external gas cylinders. With these features, high precision measurement is maintained throughout the entire measurement range.

Standard RS-232C interface makes data collection easy and remote operation possible
Analog outputs are also available for direct connection to control systems.
