ask a questionCombitherm-2 CH 3-150 is specially designed to thermostabilise materials at temperatures from –3°C to +150°C according to methods of analysis. To obtain useful functionality and decrease foot-print of instruments Combitherm-2 consists of 2 independent cooling and heating plug-in thermoblocks combined in a common electronic circuit board as well as inside a common external body. The left part of the front keyboard is responsible for setting parameters for cooling plug-in blocks and the right part — for heating plug-in blocks. Both of them are regulated independently and can realize up to 16 programs including temperature and time in each program. Peltier technology is used for cooling below room temperature; PCB is used for heating till +150°C.
Separation of cooling and heating parts from each other increases durability of the instrument and speed of temperature changing after setting a new program.
Different block types can be provided on request

Can one and the same block heat and cool?
No, one block of CH3-150 is for heating with a temperature range from +25C to +150C and the other block is for cooling with a temperature range from -3C to +20C
