Researcher at another Major University
"Now using in 7th year." 2006
Note from MHI --- We have been aware for some time that our elements are the best in the world, based on customer feedback. However even we were surprised by the life some users are getting from them. Users should recognize that the life depends on maximum temperature of use and other factors. MHI elements reach 1900°C... are we your supplier? (also see our articles in Technical Articles on how to choose the best element for maximum productivity).

Tim B, GA

Thanks again."

We could not perform our Preventative Maintenance on our ovens without the use of these elements.

Thanks again, Leo."
