Performance: 

• Microprocessor PID control/temperature calibration/automatic tuning.
• Uniform temperature control guarantees reliable test results.
• Air-tight door closure with perfect sealed packing. Heat-resistant silicone packing completely blocks high heat leakage from the inner chamber.
• Clear observation of samples. Tempered glass window with wire heater and lighting provides a clear view of samples in the chamber, beneficial for during testing. 

Safety: 

• Built-in door lock with a key.
• Automatic shut off after overheat alarm.
• Power supply leakage breaker.
• Over current protection.
• Open door alarm. 

Convenience: 

• Compact design and quiet operation.
• Three different size models available to suit user's needs.
• Corrosion resistance stainless steel chamber.
• Operating condition is clearly noticed by front LED indicator. Three different coloured lights show each status of running, stop, and power off condition.
• Cable port for introduction of external probes or wires. 50mm diameter cable port comes standard on the left side of the unit. Additional 50mm or 80mm diameter cable ports, custom ordered (optional).
• Two step stands for space-saving (optional). Single stand with a drawer provides enough storage space. Two step stand accepts loading two units to save limited space.
• User-friendly LCD controller. Colourful interactive touch type LCD controller. Set point temperature and present temperature are clearly shown together on display. Sufficient programmable control support. Operating progress can be shown in graph mode for better data understanding. Automatic start/stop can be programmed for unattended operations. Display indicates abnormal temperature changes or power failures. Selective bilingual language support (Korean/English or English/Chinese, selectable only when placing an order). Temperature and other operating parameters can be recorded using a six channel digital recorder (optional).
• Computer interface. RS-485 communication port (optional) enables connection up to maximum 32 units. Simultaneous monitoring and operating of multiples units is an available feature. Programme patterns are simple to set with the use of our software. Easy to check status of real-time operations. Graph data supports easy understanding. Storage and documentation of programmes. Data with saving capabilities in Excel and text format. Storage of programme information, back-up of value settings, recovery, and temperature values. RS-232 communication port as standard offer.
