This equipment is mainly used for sampling the release of harmful substances in decorative materials such as artificial boards and their products, wooden furniture, carpets, carpet liners, and adhesives for carpets.

The laboratory of the simulated water spray test box consists of a test bench, a water storage tank, a control box, a product dehydration buffer zone, and a spray system.

This Ozone aging testing chamber is used to test the Ozone aging resistance of vulcanized rubber, thermalplastic rubber, cable insulated jacket, under the condition of static tensile or continuous dynamic stretch deformation, or alternative of them, meanwhile with constant Ozone concentration and temperature. The Ozone aging resistance is evaluated through the clap on the surface or other characteristics variation.

The walk in environmental test chamber can simulate natural environment conditions such as low temperature, high temperature, high temperature humidity, low temperature humidity and other complicated conditions, it’s widely used to test the environmental reliability of construction materials, plastics, electronic products, food, clothes, vehicles, metal, chemicals, composite materials etc., it’s kind of common environmental testing chambers.

The dust test chamber is specially used to perform environmental test thus provide reference for scientific research, products development, and quality inspection, so as to determine the protection degree (IP) of equipments enclosure. It’s kind of common environmental test chamber.

The comprehensive drug photostability test box (with UV monitoring and control) developed by Yiheng has added visible and ultraviolet light monitoring and control on the basis of the original Yiheng GSD \ GSP \ GP comprehensive stability test box. It is an equipment for pharmaceutical and cosmetic enterprises to carry out GMP certification. Meets the light stability testing conditions outlined in the ICH guidelines.

The new generation of drug stability testing equipment integrates years of design and production experience of the company, and introduces and digests German technology. Breaking through the defect of existing domestically produced drug test boxes being unable to operate continuously for a long time is a GMP certified equipment for pharmaceutical factories.

The temperature shock test chamber is used to test the temperature shock resistance of various materials, the temperature shock resistance of material is obtained by the applicability under extremely high and low temperature condition, thus to know the material and products quality. The temperature shock test chamber is kind of very common environmental test chamber.

Introduction
The xenon lamp aging test chamber is an important means of selecting formulas and optimizing product composition in scientific research and production processes, and is also an important aspect of product quality. Application materials such as coatings, plastics, aluminum-plastic panels, paints, and automotive safety glass must undergo weather resistance tests according to product standards.
The main factors causing material aging are sunlight and humidity. The weather resistance test chamber can simulate a cyclic program of alternating sunlight, rainwater, and dew, with the tested material placed at a certain temperature under light and moisture. In a few days or weeks, it can reproduce the hazards that occur outdoors for months or even years. Artificial accelerated aging test data can help select new materials, modify existing materials, and evaluate how changes in formulas affect the durability of products.

The Sulfur Dioxide Testing Chamber is used to test the corrosion resistance of acid sulphurous, it’s kind of common environmental testing equipment.
