Why Thermopiles?

DexTempTM 1000

The Dexter Research Center DexTempTM 1000 is a small economical calibrated non-contact alerting thermometer for monitoring the temperature of objects using infrared technology. It works in conjunction with your Windows® based computer and is powered via the computer’s USB port. The DexTempTM 1000 is based on Dexter’s leadership in infrared thermopile technology, and supports easy set-up for measuring temperature without contact with an object. Read more »

World's Best Temperature Sensor

Sensor Detector = Temperature. Precise knowledge of a material, cell or living tissue temperature is a core requirement of virtually every industrial process, medical procedure or biomedical culture. Analyzing temperature is essential to monitoring the weather and the physical environments for humans, animals and crops. Fire detection is a key requirement for safety of our homes, work places, medical centers, and combat vehicles and aircraft. Dexter Research thin-film infrared sensor technology has been the most reliable and durable platform for any non-contact infrared temperature measurement. Read more »

World's Best Low-Cost Motion Sensor

Motion. We depend on it for all of our work processes and home security. But we also measure motion and regulate it. We want to know when someone is present and automatically light the way in the dark or open a door for convenience. We may want to turn on video surveillance or detect an intruder. At the core of Dexter Research Center’s Thermacon is the best passive infrared detector sensor in the world, the thermopile, manufactured by Dexter Research Center. Read more »

World's Best Gas Detectors

Oxygen. It’s life itself. No wonder Dexter Research’s thermopile infrared gas sensors are used in home, office and health safety systems to detect dangerous gases that impact oxygen levels and other gas leaks. Our infrared gas detectors have also served as multi-gas analyzers in hospital operating rooms around the world to assure patient safety during anesthesiology. Read more »
