We are full-service providers in test bench construction. Our focus is on flow, volume flow and mass flow measurement, temperature, pressure & humidity control or measurements of low flow as well as high pressure testing. Our calibration laboratory is DAkkS accredited (according to DIN EN ISO / IEC 17025 for volume and mass flow of flowing gases). We also offer factory calibrations of the measured variables temperature, humidity, absolute pressure, differential pressure and relative pressure. A DAkkS application procedure for these parameters has already been applied for. In order to meet the requirements of more complex thermal management in the field of e-mobility, we are working intensively on future topics and developing test bench solutions for battery and hydrogen technologies. The temperature control of the battery and power electronics plays an important role here, in particular the air conditioning and cooling in electric vehicles. The coolant and refrigerant-based cycle for electric vehicles is very complex. In this branch, too, the goal is to simulate the interaction of various components under real operating conditions in order to meet the requirements of tailored test bench measurement technology. Overview of some tests • Environmental simulation & thermal conditioning • Lifetime tests & functional testing • Battery simulation & battery cooling

Product Highlights:

RPD Reference gas meters The gold standard for low flow measurement The rotary piston gas meters GM16 meet the highest demands on the reliable and precise reference measurement of low flow up to 0.01 m³/h. You achieve an excellent measuring accuracy of 0.5% MW + 0.005% EW. Both variants – with 1 or 2 HF pulse generators – are suitable for operation up to 6 bar overpressure. The new generation of reference gas meters is not only suitable for air, but also for hydrogen, natural gas and other non-flammable and non-aggressive gases. With the continuous, absolutely pulsation-free and highly precise flow measurement, the reference gas meters from Ehrler Prüftechnik are the gold standard in the field of low flow measurement – also for hydrogen.
