Production Workshop - Oxygen Sensor & NOx Sensor
The core components are sourced from ZrO2 and Pt Alloy suppliers.
Our LSU4.2/LSU4.9/XF/ADV/AF/WIDEBAND products fully replace the full range of BOSCH, NTK, DELPHI, and DENSO products.
Product Line
Product range includes over 1,800 models, including Thimble oxygen sensors, Planar oxygen sensors, Wide-band oxygen sensors, and A/F rate oxygen sensors, suitable for 95% of automobiles and motorcycles.
Thimble with heater Oxygen sensor
It will improve the performance of oxygen sensors which can meet the EURO III emission standards, and some models can meet EURO IV emission standards.
A/F rate sesnor
Using the pump current structure design, they can detect a wide range of Lambda signals, which can meet the Euro IV or Euro V emission standards.
Planar oxygen sensor
This is adopted, to realize shorter light-off time and faster response, which can meet the Euro IV emission standards.
Wide-band oxygen sensor
Using a planar Zro2 dual cell limiting current sensor with integrated heater, itsmonotonic output signal in the range of lambda 0.65to air makes wide-band oxygen sensor capable of being used as a universal sensor.
NOx Sensor
Maintains consistent and reliable signal output throughout its operational life, crucial for precise closed-loop SCR control and meeting stringent Euro 6d, EPA Tier 4, and other global emissions standards.
