High / Low Temperature Thermal Shock Chamber with Touch Panel Controller
Thermal Shock Chamber.pdf
1. Description:
Three-Zone Hot and Cold Thermal Shock Resistance Test Chamber is divided into three sections: the high temperature chamber, the low temperature chamber and the testing chamber.The TFT LCD touch panel controller was made in Japan, can display Chinese / English. Big size TFT LCD panels are also adopted.High formula memory capacity can be set to 120 patterns. The maximum cycle setting is 9999 times. The maximum setting of each section is 999 Hrs 59 Mins.Provide with RS-232C communication interface device, capable of controlling / editing/ recording in the linkage with the computer and two set dynamic connection point and convenient application.Both 2 zone and 3 zone shocks can be chosen.All equipments are fully automatic, and all process are precisely controlled with PLC.If any parts have errors, the machine will automatically shuts down and a warning light switches on.Machine can be shut down automatically in case of electrical power instabilities.

Notes
1. If the high-temp exposure range lower limit + 60°C is required or the low temp exposure range lower limit -60°C, please select the “ambient-temperature exposure” option
2. If the temp fluctuation need to below ±1.8°C please select the “Low temp fluctuation package”
3. Temperature heat-up/pull down time are applicable only during independent chamber operation
4. If the automatically operated sliding door required, please select the “Automatically door package”
5. Air-cooled condenser / Water-cooled condenser both available
6. Apply on water-cooled condenser only
