The Joint Research Centre (JRC) report on the evaluation of the measurement uncertainty of PEMS available on the market is online. This report describes an experimental campaign carried out by the Joint Research Centre during 2018 and 2019 to assess zero drift of PEMS gas analyzers under real life operation.

JRC Technical Report

The results of the testing campaign showed that there is not a systematic positive or negative drift, neither a systematic step nor linear drift for any of the pollutants considered (NO, NO₂, CO₂, CO) for AIP PEMS tested.

On most of the tests performed, the zero drift for NO_X is lower than 2 ppm under a variety of ambient temperature and humidity conditions. Additional tests done on more stringent environmental conditions (high altitude mountain driving) show a similar pattern for zero drifts of all pollutants.

Effective March 4, 2017, APL Automobil-Prüftechnik Landau GmbH, based in Landau/Pfalz, acquired a major shareholding position in MAHA-AIP GmbH & Co. KG from MAHA Maschinenbau Haldenwang GmbH & Co. KG, located in Haldenwang/Allgäu.

The AIP division was originally a profit center for Maschinenbau Haldenwang which separated to become an independent GmbH & Co. KG in 2005. MAHA Maschinenbau Haldenwang GmbH & Co. KG held 70% and Mr. Anton Knestel 30% of the company shares (in addition to Mr. Christian Hartmann, one of the two managing directors since AIP was founded).

Mr. Anton Knestel maintains 30% ownership in shares and continues with the management of AIP (currently 175 employees / sales approx. € 40 million/year) with Mr. Christian Hartmann at the Haldenwang location.

An extension of the production & assembly area at the Haldenwang site is currently planned based on customer orders (scheduled beyond 2018) to consolidate and sustainably expand the technology leadership of AIP.

AIP develops and produces extremely successful individual test systems for R&D- and quality assurance centers for many of the renowned premium-class car manufacturers, their suppliers, as well as official certification laboratories in Germany and globally.

AIP supplies vehicle test systems for the realistic, reproducible simulation of road drives in laboratory operations (e.g. in the areas of emission measurement, durability testing, electromagnetic compliance testing, NVH measurement, etc.). The innovative testing technology offered by AIP is highly-recognized in the fields of electric mobility, autonomous driving, and the development of driving assistance systems.

In addition to vehicle test systems for road driving simulation, AIP is highly recognized in the areas of measurement technology for stationary and mobile (RDE) exhaust gas analysis as well as flexible test stand automation software in Germany and globally.

APL, located in Landau/Pfalz, is one of the leading engineering companies supporting the automotive service industry with a technological focus on automotive drive development and testing.

The APL-Group (formerly with currently approx. 1,400 employees) includes, in addition to APL GmbH, IAVF Antriebstechnik GmbH, APS-technology GmbH and the IAVF-Volke group audit center for combustion engines (IVP). With the latest addition of AIP as the 5th member of the APL-Group another location and all the current 175 employees have been added.

The mid-term goal is to strengthen the various business areas by applying common synergies within the APL-Group to sustainably expand market position and presence.
