What Eco Sensors does

Eco Sensors, founded in 1992 and headquartered in Fremont, California, designs, manufactures, and globally distributes affordable ozone and gas sensing instruments. It operates as a division of Interlink Electronics, Inc. (NASDAQ: LINK), following its 2008 acquisition by KWJ Engineering. The product portfolio spans industrial monitors and controllers (OS-4, OS-6, C-30ZX), hand-held instruments (EZ-1X EcoZone, C-21 VOC), electrochemical sensor modules (SM-500, SM-7/SM-EC), a UV precision analyzer (UV-100), OEM boards (OEM-1/OEM-2/OEM-3) for integration into third-party ozone generators, accessories (data loggers, alarm panels, enclosures, bump testers), and a consumer wearable (SPARROW CO & Air Quality Monitor) connected to a smartphone app. The underlying technology relies on electrochemical sensing, heated metal oxide semiconductor (HMOS) sensors, and 254 nm UV absorption for ozone concentration measurement, with detection capabilities ranging from ppb-level ambient monitoring to precision 2%-accurate laboratory analyzers.

The company makes money through hardware sales priced per unit (typically $189 to $5,900), with publicly disclosed pricing, volume discounts, and a small recurring stream from factory calibration and repair services. Go-to-market is a hybrid of direct e-commerce via ecosensors.com and a worldwide distributor network covering 25+ countries, supplemented by an OEM channel embedding Eco Sensors boards into other manufacturers' ozone generators. Customer segments are diversified across industrial facilities, water treatment, food and beverage processing, semiconductor fabrication, healthcare, commercial services (bars, hotels, pools), and field service technicians, with no disclosed enterprise anchor customers. All manufacturing is conducted in the USA at an ISO-9001 plant with IPC-610 electronics standards, NIST-traceable calibration, and CE/RoHS compliance, supporting sales into regulated workplace-safety markets globally.
