6 programmed programs can be selected, multi-level password protected entry program; program execution ends, sound and light prompts Each running program contains 30 storage parameters, of which 27 are searchable parameters and 3 are auxiliary parameters. Choose a password protection level

Preset 6 kinds of freezing programs, users can program independently according to the experiment, and can store up to 10 sets of user programs ( 16 steps in each group).

16 , 8 , none, all temperature control can be pre-programmed or temporarily set (when connected to a computer)

MRV controller, 10 32- step programs, flexible editing, storage and recall, users can use password protection program

Temperature control

Double temperature control probe detects the temperature inside the box and the temperature of the sample respectively. The measured temperature is closer to the actual temperature. The display can display the temperature inside the box and the temperature of the sample.

Temperature control set point, can choose box temperature or sample temperature, can scan detection display all the way, and has cooling waiting function, dual temperature control probe, respectively detect the temperature inside the box and sample temperature

Double temperature control probe detects the temperature inside the box and the temperature of the sample respectively. The measured temperature is closer to the actual temperature. The display can display the temperature inside the box and the temperature of the sample.

Temperature can be maintained at any point within the controlled temperature range

Dual temperature control probes, respectively detect the temperature inside the box and the temperature of the sample, and have convenient ice water temperature correction function.
