FAQ

Why does the working chamber of ovens with a temperature range of +300°C show a slightly yellowish to slightly brownish discolouration?

The discolouration of metals such as iron, steel and stainless steel under high temperatures is the result of a chemical reaction. The natural oxide layer that forms on the surface of metals is reinforced by high temperatures, and a discolouring of the surface can be observed. The discolourations of the working chamber in Memmert products represent a proof of quality. This means that these products were tested and their functions were inspected at Memmert.

 

What are the differences between the IPP and the ICP compressor models?

Technically, the difference lies in the heating and cooling technology. The IPP is heated and cooled withPeltier elements, whereas the ICP is heated via an air jacket temperature control system and cooled with a compressor. The advantages of the IPP to the user lie in its reduced energy consumption of up to 90%, in the extremely low control fluctuations, as well as its particularly smooth and quiet running, without compressor noises.

 

What is the difference between HPP and the HCP humidity chamber?

Both appliances simulate temperature-humidity combinations. Whereas the HPP constant climate chamber can be operated in a temperature range from +5 °C to +70 °C, the HCP humidity chamber works in the range from +20 °C (8 °C above room temperature) to +160 °C – and with humidity, to +90°C. The HPP is based on Peltier technology, while the HCP humidity chamber is equipped with the tried and tested Memmert all-round surface heating. Through the use of Peltier elements, the HPP constant climate chamber is designed for long-term experiments, and at temperatures close to ambient temperature and over many months can save up to 90% of energy compared to compressor-cooled appliances.
