Product Details
Oxygen Index Apparatus
Brief Introduction
ZY6155A It is applicable to strip or sheet materials with a sample thickness of less than 10.5 mm that can stand upright and support themselves. It is also applicable to homogeneous solid materials, laminates, foams, sheets and films with an apparent density greater than 100 kg/m3, as well as some foam materials with an apparent density of less than 100 kg/m3. It also provides a test method for sheet materials or films that can stand upright and support themselves, to determine the ease with which a material burns when in contact with a flame in air.
Highlights / Outstanding Features / Characteristics
1.The instrument has a reasonable structural design, making it convenient to operate, use, and maintain
2.The testing system uses an imported oxygen sensor and displays the results digitally
3.Made of high-quality painted material, it is aesthetically pleasing, rust-proof, and corrosion-resistant
4.The equipment has the following safety protection devices: power overload protection, short circuit protection, and control circuit overload protection.
