  • Heavy Duty Dynamometers

    MD-250-HD - Mustang Dynamometer

    The MD-250-HD series dyno (SE/DE) was designed to be a performance dynamometer first with the added benefit of being able to test 2-wheel-drive heavy-duty vehicles such as truck, buses and commercial vehicles in addition to the standard car or light duty pick-up. The 250-HD is certified in the states of Colorado, Nevada and Utah for use in loaded-mode diesel smog testing programs because of its accuracy and reliability. No other dyno in its class offers more value or better in-house motor vehicle testing capabilities than the Mustang MD-250-HD. For starters, the MD-250-HD boasts a 1,500 horsepower measurement capacity at a top speed of 175 mph and a powerful air-cooled eddy current brake provides the MD-250-HD-SE with 900-hp worth ofloading capacity for steady state testing. Loading capacity can be increased to 1,500-hp via the optional DE model. The 250-HD can be upgraded to the 250-HD-SE-M via the addition of a 100 or 200 hp AC motor for transient testing of electric buses to measure range and regeneration or for emissions testing of IC engines. Do not be fooled by its compact size – the MD-250-HD is a serious dynamometer with serious tuning capabilities. The MD-250-HD uses a powerful eddy current power absorber, a frictionless, air-cooled braking device, to enable it to apply variable and steady state loading. A complete control and data acquisition system lets you design a wide range of tests or select from a host of pre-configured tests included with the standard system. The 250-HD’s four roller design makes setting up vehicles a snap – simply drive onto the 250-HD and let the tires settle in between the rollers. The 250-HD can be installed above-ground or below-ground, it’s your choice. The above-ground system utilizes an optional premium platform and ramp system with an above-ground restraint kit. The addition of an axle pull-down kit help keep the tires from slipping or trying to “climb out” of the rollers.

  • Nanogravimetric Measuring Instrument

    EUREKA - BIOAGE s.r.l.

    Eureka is a QCM / EQCM (Quartz Crystal Microbalance) nanogravimetric measuring instrument capable of mass measurements in the order of nano-grams and pico-grams. Eureka can be used with gas and liquids, the cells are made by BioAge and sold with the instrument. The tool is the most versatile among those existing on the market, with an excellent quality / price ratio. It is a portable instrument as it is powered only by the PC USB port. The instrument is extremely compact, light, reliable and designed according to the current state of microelectronics. To use Eureka simply connect it to a PC USB port and install the capture software, running in Windows ™ environment,which turns out to be very simple to use, so you can do the first experiments in a very short time. For liquid measurements Eureka is an electrochemical system, therefore, electrochemical and nanogravimetric measurements can be performed at the same time (EQCM). Eureka, if connected to a self-powered portable PC, allows to perform measurements and experiments in total freedom in environments where grid voltage is not available,or experiments that are carried out in large areas in total freedom of movement. Measurements can be made on liquids, thanks to the static cell or the flow cell, or BioAge is able to design and create customized cells according to the needs of the user, varying volumes, dimensions and materials. The instrument is very versatile because the frequency measurement range can range from 0 to 50MHz, depending on the quartz crystal used. or use a gas cell designed for gas phase analysis, BioAge is able to design and produce customized cells according to the user's needs, varying volumes, dimensions and materials.The instrument is very versatile because the frequency measurement range can range from 0 to 50MHz, depending on the quartz crystal used. or use a gas cell designed for gas phase analysis, BioAge is able to design and produce customized cells according to the user's needs, varying volumes, dimensions and materials.
