Environment Chamber

Features
Control sphere graph
TH-G(General), TH-I types are available.
Wider range temperature and humidity control.Equal temperature distribution
Maintains uniform temperature and humidity, using the tangential airflow fan(180L, 300L, 408L/6.4, 10.6, 14.4cu ft) and circulating the air throughout the chamber. The heater and fan will stop when the door is opened to minimize air transfer.
No need defrosting for continuous operation. So it is convenient for long term test.Inner Door
Allows operation with minimal affect on the temperature or humidity and permits a clear interior view.(option)Vice Action Door and One Mold Door Trim
The vice-lock type door catch and foamed silicon packing give a complete seal. The door and chamber utilize a single pressed plastic trim to reduce heat transfer.Cartridge Type Water Tank
The 15L cartridge type water tank is attached and is easily replenished. Multiple sensors are equipped to check the water level, setting off the alarm when refilling is needed.Ventilation
Ventilation vent is located at the upper right side of the machine which can be connected to duct system(option)Touch Screen Type Monitor
All program functions are shown on the large LCD screen using graphics and texts. Total 120 patterns and 1200 segments(Max. 99 segments per 1 pattern) can be controlled by one set with excellent temp. range of -35~140¡£C/-31F~284¡£F).
PID auto-tuning function helps equipment to approach set point by fast and exact method. 9 different working temperatures and humidity are available with their own PID values.
BIAS function : Temperature and humidity signal can be calibrated by user with internal built-in re-calibration system. Wait on and off timer : Time can be controlled within 99hr. 59min. All the operational parameters can be checked graphically on the monitor screen. Programming, monitoring, Diagnostic messages, and etc are set very easy and convenient. Maximum 16 units of TH chambers can be controlled by one computer with RS485 interface(option)Air Filter
Filters collect matter from internal air supply, which helps to keep the compressor cool.Viewing window
Laminated membrane heating element on the glass prevents frosting in case of sub zero temperature and eliminate water-droplets caused by vapor. The subject can be observed in natural color with 2 of 3-wavelength fluorescent lights. Specification
