Beer has been a popular drink among all. Especially in summer, a beer with BBQ can be the best refreshment. For now there are many breweries producing various kinds of bear, but also producing problems of waste water treatment. The waste water which contains large amounts of organic pollutants, are…
Refrigerating fluid is the working medium in cooling systems such as central air-conditioning, heat pump air-conditioning, household air-conditioners, and other small-sized cooling equipment. The fluid circulates through the system, exchanging energy with the outside via changes in its thermodynamic states to provide cooling. Freon, the high-performing refrigerant introduced by DuPont…
The Internet of Things (IoT) is a vast information system based on the Internet, where RFID and wireless data communication connect the sensing layer with the application layer. This interconnection creates a comprehensive network that integrates human activity with the environment through sensing and control systems. The Importance of Low…
Scrubbing solution is added in the washing section during the fractional extraction process to eliminate impurities and fission fragments from the loaded organic phase. Various scrubbing solutions are used for different demands. ISWeek demonstrates how to detect the liquid level of scrubbing solutions in washing equipment before it gets too…
In computer equipment, large amounts of semi-conductors, resistors and capacitors, etc are being used. When the computers are operating, the temperature rise will somehow affect the functioning of these elements. To ensure the computers’ normal operation, not only the temperature in the room should be strictly controlled, but humidity also…
A brief instruction of the largest underground utility tunnel under construction in China The largest underground utility tunnel ever in China is being constructed in Xi’an City. The construction is expected to be finished in 2020, with its full length of 73.13km, and 182.5km cable in it. How are the buried…
IAC+SENSOR CHINA, as the predecessor of Sensor China, has been accumulating experiences and resources in sensing industry for 21 years. After strategic adjustment and cooperation with significant partners, IAC+SENSOR CHINA updates itself into SENSOR CHINA 2019, which dedicates in field of sensors. With the purpose of establishing a professional platform,…
UV sterilizing lamp is actually a kind of low pressure mercury lamp. It activates low pressure (<10-2Pa) mercury vapor to emit UV light. The spectral lines are mainly of 253.7nm and 185nm, which are both invisible. Applications of UV sterilizing lamps 1. Surface Sterilization: Surface sterilization requires the surface to be…
Understanding PM2.5 and VOCs: The Invisible Threats What Are PM2.5 Particles? PM2.5 refers to airborne particles with a diameter of 2.5 micrometers or smaller. These microscopic pollutants – composed of carbon, nitric oxides, sulfur oxides, and ammonia – originate from both natural sources (e.g., wildfires) and human activities (e.g., industrial emissions). Their…
A fresh air system is an independent air processing system consisting of a supply system and an exhaust system. These systems are categorized into ducted (with pipelines) and ductless (without pipelines) configurations. Ducted systems, which include a fresh air ventilator and pipe fittings, are ideal for industrial facilities or large offices due to their…
Volatile Organic Compounds (VOCs) pose significant health and environmental risks in industrial parks. Traditional catalytic combustion sensors struggle with slow response times and susceptibility to poisoning, especially for high-carbon-chain VOCs (≥C5). Photoionization Detectors (PIDs), such as Alphasense PID-A1 and PID-AH, overcome these limitations by enabling rapid, precise detection at PPB to PPM levels….
Smart Public Toilets: A Pillar of Modern Urban Development As cities worldwide embrace the concept of “smart cities,” public toilets have evolved from basic facilities into critical components of urban infrastructure. These spaces now reflect a city’s commitment to hygiene, sustainability, and technological innovation. However, traditional public toilets often struggle…
