Hot And Cold Temperature Thermal Shock Environmental Test Chamber
Description:
Thermal shock chamber is divided into high temperature area, low temperature area and test area three parts, each area is a unique insulation structure, so doing hot and cold impact test. High-temperature impact test or low-temperature impact test, the maximum time is up to 9999 minutes, the most cycle time is up to 9999 times. The machine can be automatically or manually cycle the impact or selectively set the two areas or three areas to impact of hot and cold. It used binary cooling system that is very effectiveness for cooling, the cooling system is divided into the air-cooled and water-cooled. It also can be connected with a computer, but the record instrument is only for optional purchase. Color LCD touch-control operation interface with Chinese and English, easy to operate.
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
