Keywords such as precision and stable control are used everywhere in sales literature and advertising, but we are the only brand supplier who can also prove this. As the very first manufacturer of temperature control appliances, Memmert has signed up to the more rigorous requirements of the current DIN 12880:2007-05 for the testing of ovens and incubators even before the new standard was official in the year 2007. And this standard has even been applied for all other product categories except water-and oilbaths.
If you look at the graphic on the measurement setup for temperature homogeneity and temperature consistency, the different requirements for 9 measurement points so far, and 27 measurement points now, as stipulated for appliances with a working chamber over 50 litres, become clear.
With an arrangement of 27 measurement points, all appliances from Memmert show how exactly the temperature corresponds to the preset temperature setpoint at all measuring points in the working chamber.
The second important change to DIN 12880:2007-05 is also predestined to separate the wheat from the chaff. Until now, performance, and thus the rapid heating up and cooling down, was the most important criterion in ovens and incubators. That is without taking into consideration the time it takes until the temperature has settled down, so that it can really be controlled in a stable manner. According to the new standard, for specifying the heating up, cooling down and recovery times, the points in time apply from which the actual temperature in the middle of the oven or incubator remains permanently within the limit deviations defined in the standard.
