The high and low temperature tester is a crucial device used to evaluate the performance and characteristics of products and materials in various fields such as aerospace, automotive, home appliances, and scientific research. It simulates extreme temperature environments—whether high, low, or constant—to assess how these items respond under different thermal conditions. This testing helps ensure the reliability and durability of components in real-world applications.
It is important to note that this equipment is not suitable for testing explosive or flammable substances. Explosives include:
1. Nitroglycerin (glycerol trinitrate), nitrocellulose, and other nitrated compounds.
2. Trinitrobenzene, trinitrotoluene, and trinitrophenol (picric acid), which are nitro-based explosives.
3. Organic peroxides such as peracetic acid, methyl ethyl ketone peroxide, and benzoyl peroxide.
Flammable materials also pose a significant risk and should not be tested in the chamber. These include:
1. Substances with a flash point below -30°C, such as ether, gasoline, acetaldehyde, propylene oxide, and carbon disulfide.
2. Materials with a flash point between -30°C and 0°C, like ethane, ethylene oxide, acetone, benzene, and methyl ethyl ketone.
3. Substances with a flash point above 0°C but below 30°C, such as methanol, ethanol, dimethoate, and amyl acetate.
4. Flammable liquids with a burning point between 30°C and 65°C, including kerosene, turpentine, isoamyl alcohol, and vinegar.
To ensure safety, always follow the manufacturer’s guidelines and avoid using any hazardous materials in the test chamber. Proper training and adherence to safety protocols are essential when operating high and low temperature testers.
