The ETR101A is a complete system designed to profile the exhaust temperature of on-road vehicles and off-road equipment. Once the temperature profile is created, its provided to the diesel particulate filter (DPF) manufacturer to aid in the selection of the correct DPF for the exhaust system.

Setup is simple and easy. Using the MadgeTech 4 Software, program the data logger for a set period of time then mount the logger (in its water resistant enclosure) to the vehicle. Data from the logger is then retrieved by using the IFC200 to download data to the MadgeTech 4 Software. Graphical, tabular, and summary data is provided for analysis and can be viewed as customizable engineering units.
