Analyzing Drinking Water with Reasonably-Priced Iranian-Made Sensor
“This project was aimed at checking the pH of water behind dams at different depths,” said Mojtaba Zareh, a graduate from Amirkabir University of Technology and a member of the research team who worked on the "pH test sensor equipped with microelectromechanical technology for drinking water analysis" project.
He noted that in order to perform this test, it was necessary to import multi-parameters water quality checkers, which cost the country a lot.
“Therefore, we implemented this project so that there is no need anymore to import and the pH of the dams' water can be measured more accurately,” Zare underlined.
”Using microelectromechanical technology, this sensor was able to measure the quality of the water behind dams more accurately and lower response time compared to its imported rivals as well as withstanding high pressures at any point of the water height behind the dams,” the AUT graduate added.
“With this sensor, one can measure the pH very fast and in a short time very accurately In the laboratory via using only a drop of water,” he added.
The researcher continued to say that the device has already been fully developed and is in the finalization stage to be presented to Iran's Water and Wastewater Administration and Water Research Institute.
Stating that the sensor has a high detection speed compared to other available glass pH detection sensors or water quality checkers, the project manager added, “This system that we designed can detect a high pH from water in less than one second with an accuracy of 0.0001 received current.”
According to the researcher, the sensor is very strong and highly resistant and does not have any problems in unexpected contact with very strong acidic environments, as much severe as stomach acid, which was tried on this sensor, and it performed the measurement very accurately.
