August 2019. Toxic and explosive gases detection.
The region of Rio Tinto in southern Spain has an acid and harsh environment similar to Mars environment, which fascinates scientists, both geochemically and mineralogically. It is because the type of minerals we find here also exist there.
The Tinto river is a coastal river that runs along the province of Huelva, in Andalusia. Since ancient times, along the river, copper, silver, gold and other minerals have been extracted. It is notable for being very acidic (pH 2) and its deep reddish hue is due to the dissolution of iron in water. Acid mine drainage causes serious environmental problems due to high concentrations of metals in the river.
For one of the new chemical plants in Rio Tinto, DURTOX-X 4-20mA detectors, with exproof and plastic enclosure for the detection of SO2 and CL2 has been installed. DURTEX HC PRO 4-20mA detectors for H2 detection have also been installed. Both designed and manufactured by Durán Electrónica.
