Details
Temperature & Humidity ChambersGreat low temperature and humidity control performance.Control range-
Temperature range from -40 to 150°C Humidity range from 20 to 95% RH
Performance
-
Microprocessor PID control / Temperature calibration / Automatic tuning. -
Advanced performance of low and high temperature and humidity control, achieved by adapting the humidification tank exterior to the chamber, added benefit for long term test. -
Water recycling and filtering system reduce water consumption for longer operation. -
Air-tight door closure with perfect sealed packing.- Heat-resistant silicone packing completely blocks high heat leakage from the inner chamber.- Two-point door latch also enhances tightness to door closure. -
Energy efficiency is achieved by optimization of the insulation system.- Even if the unit is operating at max. temperature, the surface of the unit doesn’t allow high temperatures of over 60℃.
Safety-
Built in door lock with a key. -
Automatic shut off after overheat alarm. -
Low and empty water level alarm. -
Power supply leakage breaker. -
Over current protection. -
Open door alarm.
Convenience-
Three different volume sizes are available to suit any users’needs. -
Corrosion resistance stainless steel chamber and electric polished humidification tank. -
Maintenance of water supply are easily performed with a front water tank.- Portable water container makes supplying water convenient. -
Water supply during operation is also available for long term test purposes. -
Direct water system provides user great convenience when performing long-term tests. (optional) -
Clear observation of samples.- Tempered glass door with built in heating wire.- Energy efficient, long life span LED lighting.- Wider view, inner glass door is available for monitoring of samples. (optional) -
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) -
Casters for easy mobility during installation or relocation. -
User friendly LCD controller.- 5.7 inch colorful interactive touch type LCD controller.- Set value and present value are clearly visible together on display.- Operating progress visible in graph mode allow for direct data interpretation.- Built-in SD card drive.- Trilingual support. (English / Chinese / Korean)- Temperature and other operating parameters recorded with use of an selectable recorder. (optional)- Sufficient programmable control support.
Description No Programmable pattern capacity 120 Pattern repeat time 999 Max. segments per a pattern 100 Available max. segments* 1200 Programmable process time per a segment 0 to 999hr.
59 min. 59 sec.-
* Even though the max. segments per a pattern are 100, available total segments are up to 1200 not 12000, so you need to arrange the number of segment an patterns properly -
Computer interface.- RS-485 communication port enables connection of up to maximum 9 units. Simultaneous monitoring and operating of multiple units is an available feature. (optional)- Program patterns are simple to set with the use of our software.- Storage of program information, backup of value settings, recovery, temperature, humidity values.- RS-232 communication port comes standard.
