Guaranteed Compliance: EPA 40 CFR 1065; EPA 40 CFR 1066; Euro 4, Euro 5, Euro 6; Japan 10-15 +11 Mode / JC08H/C; China SEPA IV (Euro 4); India Bharat Stage IV; Brazil PROCONVE L4-L5.
After millions of weighings over 17 years in more than 50 laboratories around the world, MTL has developed a new system that is faster, better and cheaper.
System Key Features
Processing of more sizes of filters, including 15 mm, 25 mm, 37 mm, 47 mm, 70 mm, and 90 mm
Measurement Performance Capability
Please see below for more information on our integrated Filter Weighing Software (FWS).
MTL has designed a software solution for the weighing of gravimetric filters, one which manages the entire weighing process. It can be used to operate MTL’s automated weighing system or a manual weighing operation. Having been engineered by weighing scientists, it employs a variety of quality control and methodological features to reduce measurement uncertainty and increased laboratory accuracy.
Environment – The system monitors environmental conditions and raises flags if environmental conditions fall outside of the administrator-set parameters. If preferred, the system can be set to halt weighing completely in the event of environmental non-compliance. When the environment returns to acceptable conditions, it can continue to lock out weighing until the administrator-defined period of equilibration.
Step by Step – The Filter Weighing Software package steps the laboratory technician through the process of weighing a filter, ensuring compliance with regulations as well as best practices. The system can require the weighing of metal standards and reference filters (aka lab blanks) and also require periodic calibration of the balance.
High precision weighing requires attention to detail and to method. Standard weighing, drift-corrected weighing, and substitution weighing are all different methods of using a balance that can help reduce uncertainty. The system can also require the technician to perform multiple weighings of a filter. The software then provides a mean value as well as a standard deviation.
For engine emissions customers, Filter Weighing Software had been engineered to comply fully with 40 CFR 1065 and WLTP regulations. For those in ambient air quality monitoring, it complies fully with CFR 50, Appendix L as well as Quality Assurance Guidance Document 2.12 and European ambient air regulations.
All weighings are time-stamped with the data used to create them. This includes balance readings, environmental conditions, time of day, operator of system, and more. Data are then stored in an MS SQL™ database, which can generate reports for each filter, which come with all pertinent data and confirmation that quality control procedures have been met. The end result is data with complete documentation to back it up.
Quality control is the foundation of all precision measurement systems. The MTL Filter Weighing Software package has been engineered by metrologists to provide assurance that sound measurement results will stand up under scrutiny. Environmental conditions are checked, reference filters are repeatedly weighed, and laboratory check standards are implemented.
Please note that all automated filter weighing systems come with the software as a standard feature.
