Measuring Instruments Installed in Samjiyon County

Pyongyang, November 21 (KCNA) -- Automatic instruments for measuring sulfurous acid gas and floating dust have been installed in Samjiyon County, the DPRK, as part of the efforts to turn the county into an iconic and model one of the country. Those instruments were manufactured by scientists of the Environmental Science and Technology Institute under the Ministry of Land and Environment Protection. They need no accessory equipment and no chemical reagents in operation. They are simple in structure, convenient in use and very high in accuracy. Their installation would be conducive to putting the ecological and environmental management on a higher scientific basis in the county. -0-
