ETR101A Data Logger Kit for Diesel Emissions

The ETR101A kit comes assembled and includes a data logger, temperature sensor (thermocouple type K), water resistant enclosure, interface cable (IFC200), hex screwdriver and software. Includes NIST traceable calibration certificate.

Availability: 5-7 Business Days


The ETR101A is a complete Exhaust Temperature Profiling Kit designed to profile the exhaust temperature of on-road vehicles and off-road equipment, including tractor trailers, buses, trucks over 14,000 lb, waste water vehicles, and sweepers. The ETR101A kit comes assembled and includes a data logger, temperature sensor (thermocouple type K), weatherproof enclosure, USB data logger interface cable (IFC200), hex screwdriver and software.

Setup is fast and easy. The data logger, which is contained within the water resistant enclosure, is mounted to the vehicle. Using the MadgeTech software, the logger is programmed to record for a set period, generally three to five days. Data is stored in the data logger, and is downloadable at any time via a pc or laptop computer. The complete temperature profile is then provided to the diesel particulate filter (DPF) manufacturer, aiding in the selection of the correct DPF for the exhaust system. Many DPF manufacturers, including Donaldson Corp., recommend the use of temperature profiling equipment, such as the MadgeTech ETR101A, to aid in the selection of the appropriate diesel particulate filter.

  1. Works Great Review by Brandon Hearron

    The ETR101A was easy to set up and worked great. Tech Support was very helpful (Posted on 3/7/13)

  2. as advertised Review by Denny Duckett

    The data logger and softwear do exactly what they are designed to do. (Posted on 1/18/13)

  3. Easy to Program and Download Review by Cummins Cal Pacific

    Our users love how easy the software is to program, download, and read the data. The logger and water box is 19 times smaller than the logger and water proof box we were using before. We can now install the logger in more areas with less hassle which adds to our efficiency. (Posted on 1/6/12)
