Air cooled Tecumseh Compressor Environmental Test Chamber for Electronics test
Application
Temperature and Humidity Environmental Test Chamber is able to provide rapid product temperature change rates and use varying levels of relative humidity to locate design problems prior to shipping your products, improving product quality and reliability.
Standard configuration
● Stainless steel exterior
● Energy-efficient refrigeration with exclusive electronic expansion valve system
● Specialized humidity generation and control
● Unique thermal break construction for extreme testing
● 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
● 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℃ 5%RH) for electrostatic reliability tests.
● Temperature and humidity recorder
Temperature 1 pen and humidity 1 pen.
Temperature 3 dots and humidity 1 dot.
Temperature 6 dots and humidity 6 dots.
● Defrosting circuit
The chamber automatically detects and melts the frost on the evaporator when operating below 0℃.
● Liquid or infection
In order to rapidly decrease the temperature inside the chamber, a cylinder of liquid can be connected the chamber
