Electronic Sensor Technology Receives $400,000 Order from Beijing R&D Technology.

NEWBURY PARK, Calif. -- Electronic Sensor Technology (EST)(OTCBB:ESNR), a leading provider of innovative homeland security, environmental solutions and healthcare solutions, announces the receipt of an order of more than $400,000 from its distributor, Beijing R&D Technology in China. The majority of the units will be used by China for environmental applications.

Electronic Sensor Technology has sold over 100 instruments to China, most of which are employed in the detection of pollutants in rivers and lakes. The effectiveness of the zNose in this application further underscores its versatility and usability.

The Rude Awakening's "Invest in Water" report states, "In an attempt to avert crisis, China plans to spend $125 billion over the next five years to build hundreds of new water treatment plants. That will only be the beginning of the hundreds of billions it will need to spend, if it hopes to ever provide clean water to most of its citizens."

"We expect further growth of the environmental market where the zNose[R] is used as an on-site pre-screener. Additionally, our experience in China demonstrates that the zNose[R] is a valuable instrument with unique capabilities in challenging environments," states Teong Lim, CEO of EST.
