In-cabinet Exposure Condensation Chamber

BGD 876 In-cabinet Exposure Condensation Chamber is designed according to ISO 6270-2《Paints and varnishes -- Determination of resistance to humidity -- Part 2: Condensation (in-cabinet exposure with heated water reservoir)》. This standard is different with Part 1“Continuous condensation” , but defines three cyclic program:CH(Condensation atmosphere with constant humidity), AHT(Condensation atmosphere with alternating humidity and air temperature),AT(Condensation atmosphere with alternating air temperature) to simulate different humidity environment.

It can give much better supplements and explanation for corrosion degree and defect types of coating used in different environment. Comparing to Part 1---single-sided exposure, this method add a condensation atmosphere with alternating humidity and air temperature, and mainly used to evaluate paints anti-corrosion ability under different environment.

◆ Designed with automatic ventilator, can control chamber ventilation automatically.

◆ Operator can set three different working conditions:humidification, cooling with ventilation, cooling without ventilation and its corresponding temperature & running time. Any program including total test time and cycle times can be set freely.

◆ Automatic water supply

◆ Protector for water temperature ceiling

◆ A glass observation window is designed in chamber, operator can observe specimens test status directly.
