Model 4010M Gas Dilution Calibrator

Model 4010M

The Model 4010M is a simple, but powerful Intelligent Multi-gas Dilution Calibrator that can easily perform gas dilution, multi-source gas blending, ozone generation, and gas phase titration (GPT = NO + O3 => NO2) for environmental, laboratory, or point source monitoring.

The Multi-gas system is designed to be either sequence based (gases are established, gases are assigned to source input ports, desired dilution flow defined, and output concentrations are established), or the unit can be manually controlled by the operator from the status window. Flexibility, without complicated menu systems or restrictions allow the operator to fully control the calibrator for various applications.


Users can easily navigate the menu system for setup or to check various parameters while the unit is idle or actively running. Flexibility allows any operator to easily start or stop an operation sequence, manually adjust flows while an operation is active, change ozone concentration, open/close source valves, manually purge the gas system while in operation, or view all active parameters from one simple status window. The status window will display the dilution of all gases present when using a multi-blend cylinder or the value of NO2 generated during GPT. Additionally, users can switch from one sequence to another without stopping the entire system for seamless transition during testing.


The Model 4010M calibrator uses embedded microprocessor technology to precisely deliver and control gas concentrations along multiple curve fits to linearize the desired output for the intended application. The pneumatic system uses Mass Flow Controllers (MFC’s) to precisely meter gas streams and implement multiple curve correction algorithms to deliver precise and repeatable concentrations.


The optional precision ozone generator allows the user to generate reliable, repeatable, and stable ozone for calibrating ozone analyzers or for creating NO2 using gas phase titration for NOX analyzers. The stable and consistent ozone output eliminates the need for complicated and time-consuming ozone adjustments prior to GPT operation.


Users can measure the ozone concentration from the internal ozone generator with Sabio’s optional internal ozone photometer or measure external ozone sources by manually activating the photometer or setting the photometer to continuous monitor mode. Alternatively, the internal ozone photometer can be used to control the ozone output while actively measuring the concentration using the ozone servo control mode. The Sabio Multi-gas Dilution Calibrator design exceeds US EPA calibration method requirements. Dilution components are calibrated with standards and test equipment traceable to the National Institute of Standards and Technology.
