Abstract

This research aims to develop a pH and conductivity meter in a single device for use in the field (environmental analysis) and laboratory. The choice of this project is based on the existing deficient technology in the Brazilian market in the manufacture of this type of equipment and in the experience of the members of the team in analytical instrumentation. Owing to environmental legislation, globalization and current quality norms, there has been a growing increase in imports of these instruments.As a consequence, in addition to the high cost of laboratorial analyses, a deficit in the country’s trade balance has been noted in this segment. The equipment to be developed should have an extremely accurate measuring system (1 per cent full-scale accuracy or better), and the ability to store data with date and time of acquisition to generate reports on printers or computer. The equipment should include innovations such as automatic detection of more than one type of temperature sensor; rechargeable batteries; recall of last adjusted temperature value for pH manual compensation; and conductivity, in this respect, surpassing imported models. The equipment will have guaranteed application in the chemical industry and principally, in laboratories and institutions engaged in environmental monitoring. (AU)
