Bench-top temperature and humidity test chamber

Purpose:

The programmable temperature and humidity test chamber, known as environmental chamber, is designed for testing the capability of heat-endurance, cold-endurance, dryness-endurance, and humidity-endurance. It is suitable for the industries of electron, electrical equipment, vehicle, metal, chemistry, building materials, luggage, adhesion tape, printing, packaging, etc.

Feature:

• 1.Appearance: high-texture appearance, arc shape body, and matte fringe processing of surface, planar non-reactive handles, easy operation, safe and reliable. 
• 2.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.
• 3.Water supply system: with external connected water supply system, convenient to humidification and water supply, and  automatic recycling and use.
• 4.Compressor: The compressor circulation system is made in China. it is more effective to remove condenser tube and capillary lubricants, and it adopts environmental refrigerants (R404,A).
• 5.Control Mode: adopt smart PID+SSR/SCR forward and inverse two-way synchronization output, containing advanced slope control logic. 
• 6.Controller: The controller, with multi-stage program editing temperature and humidity, adopts touch screen made in China.
• 7.System Capacity: can login multi-section, sections can be divided freely, program can be interrelated freely.
• 8.Circulation Setting: can operate multi-circulation.
• 9.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

The purpose of the controller:

This product measures and controls the ambient temperature and humidity by using the computer technology, and the advanced PID control methods.

The feature of the controller:

• 1.The display and control interface is clear and intuitive; touch-selection menu, easy to operation, stable and reliable.
• 2.Flexible Program control , cost-effective.

The technical indicator of the controller:

• 1.Five-inch Color touch screen
• 2.Two kinds of control mode(fixed value/programmable)
• 3.Sensor type: PT100 Sensor(electronic sensors are optional)
• 4.Alarm signal: Four DI external fault alarm
• 5.Temperature measuring range : -90.00℃--200.00℃, (-90.00℃—300.00℃can be customized); error: ±0.2℃
• 6.Humidity measuring range: 1.0% - 100% RH, error: ±1%RH (this model can increase the humidity control)
• 7.Interface language type: Chinese/English
• 8.With Chinese character input function
• 9.Multiple signal combined relay output, the signal is available for logical operation.(NOT,AND,OR,NOR,XOR), referred to as PLC Programming Capability
• 10.Programmable edit: can edit ten groups of programs,and every program can max edit twelve segments
