H2scan’s model 600 fixed area monitor will provide you with state of the art hydrogen specific leak detection and measurement using patented technology from H2scan and Sandia National Laboratory.

H2scan’s Series 600 fixed area hydrogen monitor will provide hydrogen-specific leak detection and measurement for hydrogen concentrations as low as 4000ppm and can be scaled to any concentration up to 5% hydrogen by volume, a range representing 10% to 125% of hydrogen’s low flammability limit. The system is designed for either ceiling or wall mount and has an RS422 capability that extends the interface from the sensor to the controller to several hundred feet. H2scan's hydrogen-specific sensor technology has no cross sensitivity to any other combustible gases, thus eliminating false positive alarms and increasing system reliability.

The HY-ALERTA Area Monitor is ideal for protecting any areas where Hydrogen is used/stored. It provides continuous monitoring capability 24 hours a day and can be linked to alarms for safe shutdown of facility.

KEY ADVANTAGES:
• Real time safety monitoring
• No false alarms from combustible gases or compounds
• Long life with recommended recalibration schedule
