The WB-O2 Nano O2 Conditioner features an extended reading scale down to 0.35 λ*, compact size, and CAN communication with our Power FT line of ECUs, preserving your ECU’s inputs for other sensors. Sending O2 data to your ECU’s datalogger via CAN bus network, instead of traditional analog inputs, is even more useful for builds using an O2 sensor for each cylinder. FuelTech’s WB-O2 acts as an O2 sensor conditioner and display for Bosch LSU 4.2 sensors. IP67 rating makes this the perfect choice for marine, offroad, and automotive applications. *The reading scale can be higher or lower than 0.35 λ, depending on sensor manufacturing characteristics.
