China ordered additional devices from a Newbury Park company to help clean up its water resources. Electronic Sensor Technology will sell China four of its zNose instruments used to detect pollutants in rivers and lakes. ETS already has 60 instruments in China. Hunan Province recently purchased 10 zNose units to assist its water pollution cleanup efforts. “We expect continued growth from these expanding markets for the zNose,” said company CEO Teong Lim. “Additionally, our experience in China demonstrates that the zNose is a versatile instrument with operating capabilities in challenging environments.”
