1. Metal plate material:
The inner and outside material is SUS mirror surface corrosion resistant plate, inner chamber two sides have sample Rail frame,it has the adjustable hang strip, heat preservation and heat insulation at least 10cm with hardness polyamine foaming.
It has the high quality bakelite and glass fiber doorframe cutting off the heat conduction. Heat-proof quality is quite good,the door airtight seal strip is the two-way wide high-temperature resistance silicon foaming.
2. Test space blowing-in circulate
Mature blowing-in system use high temperature resistance multiple-blade
wind wheel which is drived by the motor,the upside blade blow the wind in and the downside return the wind. When the temperature is -70-100℃,the error will be less 2℃
3. Controller system
Use the PLC controller which is with low energy consumption
(20W),the control system accuracy is ±0.3℃.
High mark screen
5.7 inch LCD color screen with interactive parameter input method, resolution ratio is 800*480.
Big memory capacity
120 groups / 1200 section all repeatedly:maximum is 999 (can repeated
unlimited), part repeated: support maximum 99 PC-Link, MODBUS (ASCII, RTU). And has fact curve with temperature and humidity.
Convenient and fast connect the computer
Controller use R232 port,if you monitoring the history curve and need to
playback the data,you can use editing operation.
4. Heating and humidifying system
Spiral nichrome tubular electric heating element heater, High accuracy temperature fluctuation, and with long lifetime!
Use shallow slot method to humidify. Humidity measurment use wet and dry bulb method.
Over-temperature protector:(protect the sample and the chamber)
Humidifier empty burn preventer(protect the humidifier)
5. Temp & Humi. Control Range(Specific test requirements customize)
1.Choice of wind circulation way: Forced air supply
If you have requirements on wind supplying way, this kind of air supply is the best choice.
2. Choice of water supply system: RO (Reverse osmosis)
Our equipment use pure water when doing humidity test, can automatically add water to make test more convenient.
3. Polymer film/wheel dehumidification system
If you need to do low temperature and low humidity test for long time, then honeycomb chemistry dehumidifier system will be your best choice. It can make to
10℃ 10%RH or lower.
4. LN2/LCO2 fast cooling system
We offer all kinds of imported professional LN2/LCO2 solenoid valve and related controlling system to meet your requirements of fast heating and cooling.
5. Equiped with glass door and operation hand hole on the door
If you need to move or open the test sample during testing, to equip a glass door and operation hand hole to avoid effect to test condition when open the chamber door.
6. Recorder to get test data in time
If need to record different points environmental and sample temperature, to equip a temperature recorder is a best choice.
We have stoving varnish model and stainless steel model for reference...
