Mercury use in our products WaterWe support water quality management in all areas of our life.
Water is indispensable to support the lives and industries of our modern society. At the same time, as the society and industries develop, water pollution has been serious and become a major social problem. We endeavor to preserve water environment and protect coexistence of prosperous society by providing water quality analyzers to the market.
Main Products
Automatic water quality measuring device for tap water
pH Meter Transmitter
HDM-135A
ｐH is an index to show the degree of acidity and alkalinity of water. Our pH meter plays an active role in every scene of water quality management.
Total Nitrogen / Total Phosphorus / COD automatic measuring device
NPW-160H
The device measures nitrogen, phosphorus and organic substances (COD) contained in water discharged from factories and sewage-treatment plants.
AirMeasure various atmospheric air pollutants
Air pollutants emitted from automobiles, factories and households, etc. not only affect human health, but also have various effects on the global environment including acid rain, ozone depletion, deforestation, photochemical air pollution and heat island phenomenon. We, as a leading manufacturer of environmental air pollutant analyzers, hope for sustainable development of the beautiful earth and continue to work hard to develop more advanced technologies.
Constantly Monitoring Air Pollution
Monitor the air pollution around you
Under the Air Pollution Control Law, the air pollution measurement stations were set up by the Ministry of the Environment and local governments in various places nationwide to continuously monitor the concentration of PM2.5 and nitrogen oxides in the air. Our products are installed at these measurement stations and continue monitoring air pollution.
PM2.5
Newly Set Environmental Standard
PM.2.5 is considered to have a large impact on human health. Our products are installed at the air pollution measurement stations nationwide and helping people maintain their health.
Sulfur Dioxide
Sulfur Dioxide came under close scrutiny as a pollution problem in the 1960s. Since that time, we DKK-TOA have been supplying atmospheric sulfur dioxide measuring devices to the market to help monitor air pollution.
Nitrogen Oxide
Nitrogen Oxide is the substance that directly affects human health and is considered to produce PM2.5 and oxidants.
Ozone
Ozone near the earth's surface is a pollutant. Ozone is considered to be the main component of photochemical oxidants. Our Ozone meter has been introduced for monitoring photochemical oxidant.
Main Products
Atmospheric nitrogen oxide measuring device
GLN-354D
The device monitors nitrogen oxides in the air. It is the one of the main models that plays an important role at the air pollution measurement stations.
Fine Particulate Matter (PM2.5) Monitor
FPM-377C
The Ministry of the Environment set the PM2.5 environmental standard in 2009 and the respective air pollution measurement stations nationwide started implementing the standard in 2011.
Environmental Air Pollution Measuring Vehicle
The Air Pollution Measurement Stations conduct fixed-point air pollution monitoring in various locations. When it is required to assess the level of pollution at points other than fixed points, vehicles equipped with various air pollution measurement devices are used.
GasWatch for Gas Leaks and Alarm
We supply measuring instruments that monitor and alarm gas leaks at chemical plants and watch emission of gas that is a cause of air pollution at the sources.
Emission Gas Analyzers
Emission Gas Analyzers measure concentration of air pollutant substances contained in emission gas from refuse incineration plants and various factories and play an active role in process control for treating these pollutant substances.
