Challenge Technology has dedicated over 23 years of research, 
developing high quality respirometers, for monitoring of respiration for the 
purpose of understanding and optimizing biological wastewater processes.  
Challenge Technology began manufacturing our initial product line of 
aerobic / anaerobic research level respirometers in 1990, using a patented, 
gas-flow measuring system developed by Mark Kuss, the president of 
Challenge Technology.  Challenge Technology continues to manufacture 
the highest quality respirometers, which support the wastewater, soil, 
compost, biofuel and bioremediation industries.  The Challenge Technology
respirometers are the most requested respirometers, and have been sold 
in over 30 countries around the world and across Canada, Mexico and the 
United States.

This same experience and dedication is seen in the full line of Challenge 
Technology products, including the latest developments in material testing 
equipment.  Challenge Technology, seeing the need to innovate more 
precise test procedures for concrete and asphalt materials, has developed  
a unique line of automated testing equipment that prove to be the best 
available for repeatability and reliability.  By removing as much human error
as possible and by automating test procedures and developing new 
measurement technology, Challenge Technology offers cutting edge 
products for the civil engineering field.

Challenge Technology has a team of professionals, with facilities and skills, 
to take products from a concept, to a working model, to a production 
version.  We have extensive design experience, utilizing a wide variety of 
materials and technology.

Mark Kuss is, also, the designer and inventor of the Pro-View Wireless Live 
View, a wireless, remote viewfinder for digital SLR cameras, and 
Target-Cam,  a field-ready, portable, wireless digital target viewing system.
