Description

technical field [0001] The invention relates to a constant temperature device, in particular to a multi-temperature zone constant temperature device. Background technique [0002] The storage of food, the experimental research of biological materials, the experimental research of various medical items, etc. all require different constant temperature environments. More importantly, performance experiments at different temperatures are often required for the same experimental material at the same time. Therefore, It is particularly important to be able to provide multiple constant temperature environments with different temperatures at the same time. [0003] At present, the constant temperature devices on the market are all single boxes, which can only provide a constant temperature environment corresponding to a certain temperature at any time, which results in that the experiments on a large number of experimental materials with different temperature requirements can only b...

Problems solved by technology

[0003] At present, the constant temperature devices on the market are all single boxes, which can only provide a constant temperature environment corresponding to a certain temperature at any time, which results in that the experiments on a large number of experimental materials with different temperature requirements can only be carried out one time at a time, which is time-consuming. laborious

If you want to do it at the same time, you can only buy multiple thermostats, which will not only greatly increase the cost, but also greatly increase the space occupation, which will great
