Biosan SIA., Ratsupites 7, build. 2, Riga, LV-1067, Latvia, Phone: +371 674 261 37, Fax: +371 674 281 01, E-mail: [email protected], www.biosan.lv CH 3-150, Heating and cooling thermostat, Combitherm-2 DESCRIPTION Combitherm-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 SPECIFICATIONS Heating block Temperature setting range Heating block Temperature control range Heating block Setting resolution Heating block Stability --- Without thermoblock Without thermoblock Temperature calibration coefficient range Cooling block Temperature setting range Cooling block Temperature control range 23°C below ambient ... 5°C below ambient Cooling block Setting resolution Cooling block Stability ---- Digital time setting Timer sound signal Display User adjustable programs (temperature and time) Overall dimensions (W×D×H) Weight Input current/power consumption Power supply CH 3-150, Heating and cooling thermostat, Combitherm-2
