Purpose:
Constant temperature and humidity tester, as know as environmental
testing machine, test various materials for their heat resistance,
cold resistance, dry resistance, humidity resistance performance;
suitable for electronics, electrical appliance, food, vehicles,
metals, chemicals, building materials, bags, adhesive, printing,
packing and other factories quality control purposes.
Appearance: high-texture appearance, arc shape body, and matte
fringe processing of surface, planar non-reactive handles, easy
operation, safe and reliable.
View window: rectangle complex layers of glass view window can be
used for observation specimen when doing testing. With anti-sweat
heater unit of the window can prevent water vapor condensing water
droplets, and high-brightness PL fluorescent lamp keeps box
lighting.
Water supply system: with external connected water supply system,
convenient to humidification and water supply, and automatic
recycling and use.
Compressor: Compressor circulation system adopts French Taikang”
Brand, it is more effective to remove condenser tube and capillary
lubricants, and full ranges of series adopt environmental
refrigerants (R404,507)
Control Mode: adopt smart PID+SSR/SCR forward and inverse two-way
synchronization output, containing advanced slope control logic.
Controller: with multi-stage program editing, and temperature and
humidity can be made quick (QUICK) or slope (SLOP) control.
System Capacity: can login 150 group of programs x 1500 sections,
sections can be divided freely, program can be interrelated freely.
Circulation Setting: can operate 9999x999 times circulation, and
can be divided 5 groups of independent part circulation.
Time Signal: 3 groups of sequence control output interface, with 10
kinds of time control mode, convenient to operate START/STOP
sequence plan of external drive component.
Safety Detector: 15 items of full-function system detects, ensure
the safety of machine operation, and can automatic display failure
time, items and resolved method.
