The Cerex HOUND is a point analyzer designed to detect part per billion (ppb) to percent level concentrations of multiple gases within a mixture. The HOUND measures gas concentrations utilizing light absorption from a long path beam of UV radiation. A broadband miniature spectrometer collects the gas fingerprint data and the advanced software compares the results to a calirated reference, or "library spectra". Ultraviolet spectroscopy principles are similar to common infrared methods, but offer lower detection capability for many chemicals associated with impact on Human Health. The onboard PC reports reliable realtime concentration data up to once per second and stores all spectral data for later post processing or archiving.

 

Data Quality Assurance. Our advanced software utilizes a proprietary photometric Differential Optical Absorption Spectroscopy (DOAS) algorithm, which eliminates the need to take clean air backgrounds. All the calculations are performed on a onboard PC which runs user familiar Windows XP. The system can be span checked at any time, however, the measurement and analysis method employed in this system has the true calibration inherent in the fixed library references. Unless there is a system fault, calibration is never needed. The system is self compensating for all normal sources of drift found in analyzers including temperature, aging of the lamp, degradation of the optics, etc.

 

Data Output. The HOUND reports real time data on the front panel display, or remotely through Virtual Network Computing, VNC, using wired Ethernet or WiFi, or optional onboard server software. Additionally, concentration data is available through wired or wireless serial transmission, 420mA output, and 05VDC analog voltage. All spectral data is also stored locally on the internal solid state disk which can be copied onto a standard USB key.

 

Software Features. All Cerex analyzers come with proprietary Continuous Monitoring Software, CMS, for data collection, analysis, and charting. CMS provides operators with stand alone process monitoring and control with sample specific integrated programmable relays an analog outputs.

 

Product Quality Assurance. Cerex places customer service and support as its highest priority. We encourage the customer to be informed upfront of the pros and cons of each system and competing technologies. Cerex is committed to long standing relationships with their customers that do not end after the sale of an analyzer.
