The sulfur hexafluoride detector has the characteristics of flexible use and simple operation. The SF6 Gas Detector is used in various gas leakage places, such as: city gas, petroleum, chemical, pharmaceutical, steel, special industrial plants and other fields. The explosion-proof level of the SF6 Gas Detector is CT6.
Monitoring of SF6, how damaging to the climate is SF6?
SF6 in its pure state is inert, colourless, tasteless, non-flammable and nontoxic. It is heavier than air, and can accumulate in cable trenches, pits and tunnels. A volume greater than 19% in the air may cause asphyxiation. An appropriate risk assessment should be undertaken in order to determine if cable trenches/tunnels are classified as confined spaces, in which case appropriate control measures for access must be implemented.
Identify important causes of SF6 exposure and find sulfur hexafluoride
Under normal circumstances, it might be considered rare to be exposed to SF6 without enough oxygen dilution; but for utility employees, this type of exposure is well within the normal course of duties when working on SF6 filled switchgear in enclosed spaces. Indeed, if a substantial quantity of SF6 gas leaks in an enclosed area, it can pose a real danger of asphyxiation to personnel.

Common water quality monitoring sensors
Background
In today’s society, people pay more and more attention to environmental protection. Water quality monitoring sensors are essential equipment for water environmental protection in some industries. However, different industries have different requirements for monitoring parameters, so the selection of water quality monitoring sensors is also different. For example, industrial wastewater is mostly monitored for heavy metal content. Drinking water plants may need to monitor various parameters such as microorganisms, organic matter, ammonia nitrogen, total phosphorus plasma, and heavy metals.

The important role of water conductivity sensor
What is conductivity?
The conductivity of water is determined by the ability of the fluid to pass current. The conductivity is measured in Siemens units. Usually expressed as S/cm. The conductivity value usually has two basic formats, namely actual conductivity and specific conductivity. Due to the many substances or sediments in the seawater, the conductivity in the seawater is much higher. But a high conductivity value may also mean high pollution. May cause harm to the environment. For example, in groundwater applications, conductivity can be used to identify saltwater intrusion. Conductivity can also be used to determine pollution events in freshwater environments. It can quickly determine water quality changes, which is very suitable for preliminary research or deciding the focus of monitoring activities.
Water quality conductivity sensor
The water quality conductivity sensor monitoring data can be remotely monitored and recorded by connecting the transmission output to the recorder. It can also be connected to the RS485 interface for monitoring and recording. At the same time, the device has 2 relay interfaces, which can set the output of the alarm point. It is widely used in sewage treatment plants, pure water conductivity detection, aquaculture conductivity detection. River water and seawater conductivity detection and many other environments.
Precautions
Do not put the electrode directly in the water. Before installation, be sure to use the raw material tape (3/4 wire) to do a waterproof seal to prevent water from entering the electrode and causing the electrode cable to short-circuit.
In the process of water cut, you need to make sure that the electrode is immersed in the liquid to be measured or wear a protective cap with a protective liquid in the protective cap. In winter, if the water temperature is low for a long time, antifreeze devices should be installed or water should be added indoors for storage. Otherwise, the service life will be shortened.

How much do you know about the portable dissolved oxygen meter for water quality?
What is DO (dissolved oxygen)?
Molecular oxygen in the air dissolved in water. The content of dissolved oxygen in the water is closely related to the partial pressure of oxygen in the air and the temperature of the water. Under natural conditions, the oxygen content in the air does not change much. Therefore, water temperature is the main factor. The lower the water temperature, the higher the content of dissolved oxygen in the water. The molecular oxygen dissolved in water is called dissolved oxygen and is usually denoted as DO. Expressed in milligrams of oxygen per liter of water. The amount of dissolved oxygen in the water is an index to measure the self-purification ability of the water body. The portable dissolved oxygen sensor is a water quality monitoring sensor. It can detect the dissolved oxygen content in the water.
Why measure dissolved oxygen?
The content of dissolved oxygen in water has an impact on the economy. For example, too high or too low dissolved oxygen in aquaculture ponds will cause death or reduction of aquatic products. The dissolved oxygen in the sewage tank (exposure tank) will help the sewage treatment. If it is too low, the effect will be weakened, and if it is too high, energy will be wasted.
Application scenarios of portable dissolved oxygen meter:
It is widely used in aquaculture and biological reactions. Environmental testing, wastewater treatment. Petrochemical, metallurgical electronics. Laboratory field, scientific research and biological fermentation. Medical field; food and beverage; environmental protection tax treatment and many other fields.
