Product Description

Programmable Constant Temperature and Humidity Testing Machine 

Standard configuration
Sight window*1, cable port(portΦ 50mm)*1, shelves*2, chamber lamp*1, power cable *2m
No fuse breaker, over pressure, overheat and over current protection for compressor,
Over temperature protection, overload protect of the blower, dry heat protection

Optional accessories
Cable Port: Φ 100mm cable port is available
Shelves
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.
Dehumidifier
The rotation regenerating dehumidifier M-120 ensures precise control of low humidity (5° C 5%RH) for electrostatic reliability tests.
Temperature and humidity recorder
-100 to +150° C/0 to 100%RH 100mm with effective width 100mm and 2 pen
Temperature 1 pen and humidity 1 pen.
-100 to +150° C/0 to 100%RH 100mm with effective width 100mm and 6 dots
Temperature 3 dots and humidity 1 dot.
-100 to +150° C/0 to 100%RH 100mm with effective width of 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 0° C.
Liquid or infection
In order to rapidly decrease the temperature inside the chamber, a cylinder of liquid can be connected to the chamber.
