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…
SST is a sensor and instrument manufacturer in the UK with over 10 years of experience in supplying sensors for industrial applications. They mainly design and produce photoelectric level sensors as well as provide gas sensor solutions. Their major products are: Small-sized solid optical level sensor, highly reliable and accurate,…
People spend 1/3 of their lives on sleeping. High sleeping quality can eliminate tiredness and help our body and brain to relax and recover. However, with living pace accelerating, people are being haunted with sleeplessness. Air purifier can enhance sleeping quality to a certain extent. Researches have found that people…
In today’s accelerated world, insomnia has become a silent epidemic. Millions toss and turn through the night – struggling to fall asleep or waking repeatedly – only to face exhaustion and anxiety the next day. Chronic sleep deprivation isn’t just about fatigue; research links it to serious health consequences including…
Home, sweet home. When we are at home, we feel safe, relaxed and beloved. However, due to the worsening air pollution, our homes are being threatened by harmful matters like VOC, haze and PM2.5. Cannot breathe fresh air, we are not as healthy and happy as we used to be…
“2018 Central Ventilation Industry Conference” was held in Shanghai by Indoor Environment Control and Health Branch of CAEPI recently, during which many participants discussed keenly about the breakthroughs in central ventilation industry. According to a survey done by WHO, morbidity rate of respiratory diseases and flu in China stays at…
Digital printing involves inputting a designed pattern into a computer with digital technology, editing it by CAD, and using a computer-controlled micro-piezo ink nozzle to directly spray the dye liquor onto the textile to form the desired pattern. With technology being gradually improved in recent years, the development of digital…
Effective management of high-security areas like data centers, IDC facilities, and power distribution cabinets demands more than basic room-level checks. Often, while all monitoring points show normal conditions, critical equipment interiors face hazardous microclimates. Internal heat dissipation causes over 50% of hardware failures as electronics generate concentrated heat. This makes internal temperature…
Before talking about PM2.5, let’s have a look at the concept of PM10. In the air we are breathing every moment, there are plenty of particle matters which are named as Total Suspended Particulate(TSP). TSP is a major component of air pollutants, the ones of which with their diameter below…
Hydrogen chloride (HCl) is a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond. It is a colorless gas with pungent smell, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrochloric acid is a solution…
What is an ultrasonic sensor? An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses. These pulses relay proximity information of relevant matters, so that the sensor can output its distance to the matter. How do ultrasonic sensors work? Ultrasonic sensors transfer ultrasonic signals to other energy signal…
