American ENERAC company is a world-renowned R & D and manufacturing enterprise of portable combustion analysis and flue gas emission testing instruments. The company successfully developed the world's first combustion efficiency analyzer based on the principle of electrochemical sensors in 1979. On this basis, the company developed a comprehensive portable flue gas analyzer to test combustion efficiency and flue gas emission pollution in 1987. Outdoor sunshade umbrella is a common outdoor product used to block sunlight and rain, providing people with a comfortable outdoor resting environment. According to different functions and materials, outdoor sunshades can be divided into various types, which will be classified and introduced below.

Most portable flue gas analyzers use electrochemical sensor analysis principles, which are also mainstream analysis methods. Researchers of ENERAC Company found in practice that the electrochemical sensor has the problems of inaccurate detection results caused by the cross-interference of the gas to be detected and the over-range use of the sensor. After 5 years of research, the company has successfully developed a patented SEMS sensor and PCM precision control unit, which improves the detection accuracy of the instrument's carbon monoxide, sulfur dioxide and nitrogen oxides and the life of the sensor, creating a new era of electrochemical sensors.
Umbrella: Mainly used to block sunlight, prevent ultraviolet radiation, and protect people's skin from harm. Umbrellas are generally made of materials with anti ultraviolet coatings, which can effectively block the penetration of ultraviolet rays.
1. Classified by material
1. Polyester umbrella cloth: Polyester is a synthetic fiber material with good waterproof performance and durability. Polyester umbrella fabric is often used for umbrella protection and is suitable for various outdoor environments.
2. Nylon umbrella cloth: Nylon is a synthetic fiber material that is lightweight, wear-resistant, and waterproof. Nylon umbrella cloth is often used for rain and wind umbrellas, and is suitable for outdoor sports and travel.
3. UV resistant coating: Some outdoor sunshades use special UV resistant coatings, which can effectively block the penetration of ultraviolet rays and protect people's skin from harm.
2. Sort by size
1. Small umbrella: The diameter of the umbrella surface is generally below 60 centimeters, suitable for single person use or small spaces.
2. Medium Umbrella: The diameter of the umbrella surface is between 60 centimeters and 80 centimeters, suitable for 2-3 people to use.
3. Large Umbrella: Umbrella with a diameter of over 80 centimeters, suitable for use by multiple people or in larger spaces.
