Automobile lamp dual temperature zone fog test chamber

The dual-climate environment tester for car lights is mainly used for the fogging test of car lights. It simulates whether fog will be caused when the car lights are started in a heavy rain environment and the temperature inside and outside the lamp is inconsistent, thereby affecting the lighting performance of the car lights.

Temperature range -50℃~+150℃(left and right zones)
Humidity range 10%~98%R.H(left and right zones)
Temperature and humidity resolution 0.01℃/0.1%
Temperature and humidity fluctuation ≤±0.5℃/≤±3%RH

Product Description

The dual-zone test chamber is a device specially designed to simulate the fogging of automotive lamps under different temperature and humidity conditions. The main structural features of the test chamber include two independent temperature zones, which simulate the temperature and humidity conditions of the surface (outdoor environment) and back (engine environment) of the automotive lamp respectively.

The main structural features of the test chamber include two independent temperature zones, which simulate the temperature and humidity conditions on the surface (outdoor environment) and back (engine environment) of the car lamp. By precisely controlling the temperature and humidity of each temperature zone, the test chamber can simulate a variety of complex actual use environments, thereby comprehensively evaluating the anti-fogging performance of car lamps.
