Welcome to visit and advice!  There you will have a new concept of opur environmental test chambers. You will find  purchasing become easier and more smoothly.

Standard configuration
Sight window*1,  cable port(portΦ50mm)*1,   shelves*2,    chamber lamp*1,  power cable *2m
No fuse breaker, over pressure,over heat and over current protection for compressor,
Over temperature protection, over load protect of blower, dry heat protection
Optional accessories 
Cable Port: Φ100mm cable port is available
Ro-type water purifier:R-80/day
Provide to keep the humidifying heater and wet bulb wick free from scale.
Inner glass door with operation port  
A glass door can be provided behind the main door so that specimens can be observed. Two operation ports of 130mm diameter are used for handing specimens inside the chamber without opening the glass door.
The rotation regenerating dehumidifier M-120 ensures precise control of  low humidity (5ºC 5%RH) for electrostatic reliability tests.
Temperature and humidity recorder  
-100 to +150ºC/0 to 100%RH 100mm with effective width 100mm and 2 pen
Temperature 1 pen and humidity 1 pen.
-100 to +150ºC/0 to 100%RH 100mm with effective width 100mm and 6 dots
Temperature 3 dots and humidity 1 dot.
-100 to +150ºC/0 to 100%RH 100mm with effective width 180mm and 12 dots
Temperature 6 dots and humidity 6 dots.
Defrosting circuit  
The chamber automatically detects and melts the frost on the evaporator when operating below 0ºC. 
Liquid   or   infection  
In order to rapidly decrease the temperature inside the chamber, a cylinder of liquid can be connected the chamber.  

If you want high temperature uniformity  chamber, we creat a new design recently.  The temperature uniformity  can reach 0.5 Deg. Therefore, the soaking speed is increased greatly, and the yield rate will be improved  accordingly.

Installation environment 
Distance from the wall to both sides and rear of chamber more than 800mm, to the front more than 1500mm. Provide independent power distribution switchgear and humidification condensate drains, and external power connector device is necessary  
Ground level, well-ventilated , non- flammable, explosive, corrosive gases and dust
No strong electromagnetic radiation nearby
With floor drain ( less than 2 meters from the refrigeration unit )
Venue floor load capacity : not less than800kg/m2
Leave adequate space for maintenance
