Velit Lambda AFR clips into a heater's exhaust and reads combustion in real time, so you can see a rich or lean burn before it turns into carbon buildup or a heater that won't start. On any gasoline or diesel air heater it handles live lambda readings, rich/lean diagnosis, install checks and pre-season health checks. On compatible Velit heaters it also takes over closed-loop fuel control, automatic altitude compensation, Smart Priming and Smart Ignition.
