AIRSENSE - Model GDA-FR -First Response Portable Gas Detector Array
Portable detector for first response units offering detection and identification of chemical hazardous gases results within seconds. Due to its unique patented combination of different sensors the GDA-FR is able to detect and identify a very broad range of chemical substances in the range ppm - ppb. The GDA-FR comprises a combination of various sensors: an ion mobility spectrometer (IMS), a photo ionization detector (PID), two semiconductor gas sensors (MOS) and an electrochemical cell (EC). As a result, it not only enhances the ability to detect a wider range of compounds, but also improves the substance identification capability through combined evaluation of all sensors. With this capability it is a suitable detector for situations where no prior knowledge of leaking chemicals is available.
With its simple method of operation the GDA-FR is used as a general detector, checking every second for potential chemical risks and informing the operator. The user is protected with the highest level of safety.
The GDA is in use worldwide. It has been used to secure many public events as well as in counteracting chemical threats after accidents in industry or on transportation systems.
Portable detector for hazardous gases and chemicals
The portable Gas Detector Array is a battery operated analytical instrument specifically designed to measure and monitor most common gases. This instrument is used by Police, Fire Departments and many different operators from public security.
The GDA has been designed for the detection and identification of Toxic Industrial Compounds (TICs) and Chemical Warfare Agents (CWAs) - with optional expansion to the range of the most common explosives.
With its Hybrid Sensor Array it alerts to a wide range of hazardous gases. It offers high level safety without the need to select the “right” detector.
Alarms are released as soon as gases appear in dangerous concentrations - whether it is in ppb or ppm range. Compounds matching with the adaptable libraries are automatically displayed on screen. The GDA is permanently ready-to-use. A specialized gasflow control allows faster deployment and the unit retains its sensitivity and reliability.
