ur Thermal Shock Chamber offer totally new performance and style. Shortened temperature recovery times and temperature rise and fall times, reduced power requirements, the use of HFC refrigerants, and the adoption of touch panel instruments for operation settings make the TSA series even easier to use and more environmentally friendly. - A temperature recovery time of less than 5 minutes is realized for the 2-zone (+150°C and -65°C) and 3-zone circulated air (less than 10 minutes for the TSA-201S and TSA-301L). - The air blower mechanism uses a side flow system for superior sample temperature distribution. - Material designations are used on plastic components to facilitate easy material recycling. - Operation noise generated by the unit has been reduced to less than 65 dB to improve the work environment.
