1、 Product Introduction:

The temperature/humidity/salt spray composite test chamber is designed to simulate the most realistic natural conditions in accelerated corrosion testing. It simulates the conditions commonly encountered in natural environments and combines them with several times the harsh conditions of the natural environment, such as salt spray, dry, humid, room temperature, low temperature, etc. It can be tested in any order or separately.

The main test products are aimed at products used under intense environmental changes, such as automotive parts, aviation equipment, photography equipment, building materials, electroplating coatings, and electronic motor systems, which are suitable for metal electrochemical corrosion resistance.

2、 Product features:

Using an LCD digital display color touch screen temperature and humidity controller (OYO U-8256P from Japan), the temperature and humidity test curves can be fully recorded.

Control method: Temperature, humidity, and temperature and humidity can be controlled by program alternating control.

Program group capacity: 140Pattern (group) 1400Step (segment) Each program group can have up to 99 Repest segments.

Each execution mode time can be set arbitrarily from 0-999 hours and 59 minutes.

Each group can freely set a partial loop of 1-999 or a complete loop of 1-999.

Equipped with power-off memory function, it can continue to perform unfinished tests after power restoration.

Can be connected to a computer via RS232 interface.
