Product Details

Use

The constant temperature and humidity testing Chamber has the simulation product under the climatic environment temperature and humidity combination condition (high and low temperature operation & storage, temperature circulation, high temperature and high humidity, low temperature and low humidity, condensation test, high and low temperature gradient test, etc.

Comply with international standards (IEC, JIS, GB, MIL...)In order to achieve the consistency of international measurement procedures (including test steps, conditions and methods), avoid cognitive differences, and reduce the scope of measurement uncertainty.This series of products have the characteristics of wide range of limit temperature (humidity) degree and high accuracy of actual temperature (humidity) degree.In line with the "environmental experiment ten conditions" series of standards in the standard requirements.

 

Theory

Programmable constant temperature and humidity test box fr-1204 is the product placed in the specified temperature and humidity, to see the product's high temperature resistance, low temperature resistance, and the ability to resist humidity, then constant temperature and humidity machine at the same time with the heating, cooling, humidification, dehumidification ability.

The humidification system of the constant temperature and humidity test chamber is roughly the same as that of the heating system.It's a heater that turns water into steam;Complete the purpose of constant temperature and humidity machine humidification.

The dehumidification system of the constant temperature and humidity test chamber is also completed by the refrigeration system. The evaporator is placed in the constant temperature and humidity machine.Relatively cold, constant temperature and humidity machine inside the high humidity gas will be cold object condensation into liquid;Such repeated box of high humidity will be very few, to achieve the purpose of moisture reduction
