HORIBA MEXA-700λ Air fuel ratio tester基本介绍 
 
 
 
概要
 
 
 
 
 
Original front panel providing enhanced visibility and operation Restorable sensor coefficient data with new memory back-up function.
 
 
Previously MEXA-700λII used know-how and ingenuity gathered from HORIBA air-to-fuel ratio measurement technologies used worldwide, to provide the highest level of performance.
The MEXA-730λ adopts this performance and adds original design for enhanced visibility and operation.
A new sensor coefficient data memory function makes it possible to restore back-up data, providing faster start-up times and saving valuable operation time.
 
 
This enhanced device will meet your multiple testing requirements covering applications from, lab analysis of air-to-fuel ratio, excess air ratio and oxygen concentration, to on-board real time measurement.

Meets your need to measure air-to-fuel ratio under various applications
 
 
Provides stability with air-to-fuel analyzing sensor
To meet the stringent measurement conditions of research and development, the on-board auto sensor is produced specifically for air-to-fuel evaluation. -to-fuel ratio measurement, the MEXA-730λ provides reliable accurate performance.
Sensors of MEXA-700λ/700λII can be used with MEXA-730λ.
 
 
Wide measurement range applicable to lean-burn engine development
The MEXA-730λ,including lean-burn.
 
 
Versatility inherited from MEXA-700λ
The MEXA-730λ can be mounted on vehicle dashboards, table-tops,.
 
 
Can be stacked for multi-channel measurement
Multi-channel measurements are easily accommodated by using several MEXA-730λ units simultaneously, for example, to monitor air-to-fuel ratio in each cylinder.  The stable and compact design of the MEXA-730λ permits the instruments to be safely stacked for maximum convenience.
 
 
Small DC drive allows on-board mounting for convenient operation from the dashboard or complementary locations.
