Applications
Applicable to environmental adaptability and reliability test in such industrial units as electronics, electrical appliance, battery, plastics, food, paper product, vehicle, metal, chemistry, building material, research institution, inspection and quarantine bureau, university etc.
Features
1. The separation of humidifier circuit from electric circuit improves safety and protects the circuit against the leakage of water supply line.
2. Chinese and English optional, LCD touch screen, full color, easy operation and program, high accuracy of 0.1C or 1%R.H.
3. Able to display the relative date and information of the whole operating system in running mode, graphic display, precautions, maintenance and troubleshooting appear on the screen instantly.
4. The Sirocco fan motor provides greater cyclic airflow to avoid dead corner in the chamber so as to obtain high temperature and humidity uniformity.
5. The system of heating up, heating down, dehumidifying, and humidifying can be operated independently so as to reduce the cost of testing, extend the operation life of the machine and decrease the failure rate.
6. The ideal simulation test chamber for all heat and cold testing between -40 ºC and 180 ºC temperature range
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
● 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.
