System only includes the Horiba AFR Analyzer no power cable or probe is included. Shows an error without the sensor connected. Unit powers on but displays Error 04 due to no sensor being connected during testing. This listing includes the analyzer only; no sensor is included, so the unit cannot complete normal measurement startup. Error 04 appears consistent with the missing sensor connection rather than an internal fault.

From Horiba:

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.

About this system, "The HORIBA MEXA-730λ is a compact digital air-to-fuel ratio analyzer built for fast, real-time AFR, lambda, and oxygen measurement in demanding engine and exhaust development work, with a wide display range of 3.99 to 500.0 A/F, λ 0.275 to 30.00, and O₂ 0.00 to 99.99 vol%, plus typical 80 ms response time, 0 to 5 V analog output with scaling, standard RS-232C connectivity, and a small 10 to 30 VDC, 50 W control unit that is light enough for dashboard, benchtop, rack, or mobile/on-board installation. HORIBA positions the MEXA-730λ as a UEGO-based analyzer for engine research and development, engine tuning, catalyst development, exhaust gas adjustment, on-board evaluation, and ECU adjustment; it also supports stacked multi-channel setups for per-cylinder monitoring and is compatible with MEXA-700λ/700λII sensors, making it a strong fit for automotive R&D, motorsports tuning, dyno cells, lean-burn combustion development, catalyst and aftertreatment work, prototype calibration, transient engine mapping, fuel system optimization, emissions development, powertrain labs, university research, and any workflow needing clean, responsive AFR data instead of slow or janky wideband readouts."
