Electronic Sensor Technology extended its contract with a Chinese company to distribute its odor detection equipment in that country. Newbury Park-based EST has used Beijing R & D; Technology as a distributor since 2005. The companies have sold more that 70 units of zNose instruments used to measurement of pollutants in water in two years. “We expect China to continue to be a major and growing market for us in connection with their continuing efforts to improve the environment as well as their continued industrial growth,” EST President and CEO Barry S.
