NOx – a nitrogen oxide sensor is a high-temperature device/sensor built/designed to detect nitrogen oxides in combustion environments such as an automotive or truck exhaust emissions.

The development of exhaust gas NOx sensors started in the 1990s. The most recent area of NOx sensor application are SCR systems for light and heavy duty diesel engines. To satisfy various OBD requirements, SCR systems typically use a NOx sensor downstream of the SCR catalyst. If excessive NOx or ammonia concentrations exist at the SCR outlet, an OBD malfunction/fault will be triggered, as NOx sensors are sensitive to both gases. Should such fault/error be detected, vehicle ECU will start limp mode timer, and, after a certain number of hours, starts etc.. (different from one manufacturer to other) the vehicle will enter limp mode.


Most tractors, combines, excavators, cranes and other mobile engines that run on diesel, but not on roads, are equipped with SCR/Adblue technology, which requires Adblue fluid.

SCR technology and AdBlue for NOx reduction can be found in most non-road engines/vehicles such as:
• Agriculture vehicles such as tractors and combine harvesters
• Mobile cranes
• Engines/machines used in harbours and airports
• Excavators and engines used in mines or construction


As a global leader in heavy transport electronics, we continue to grow and develop new solutions. We are very proud to welcome our new products and services we are able to offer to our customers as of Spring 2019.


This emulator is specifically developed for Scania Terex Euro5 trucks. Terex SCR system is different to other Scania Euro5 models and it is run by different software. Simple Euro5 emulators suitable for P or R series for example, would not work on Terex models, nor would any other emulator. Scania Terex require a bespoke emulator and Can Logic is proud to be able to offer this product to our trade and retails customers as of now.


It is legal to produce, stock, sell and have adblue emulator in your possession, but it is not legal to use it in your vehicle on public roads here in UK as well as throughout the EU. By using adblue emulator driver and the operator will be breaking the law.

There are plenty of legitimate uses for adblue emulators and other emission cheat devices – agricultural transport, on-site construction machinery, vehicles operating or being exported outside of EU and many others… However, it is against the UK Law to use any emission cheat device in the vehicle, which is operated on public roads.
