The Jerome® 651 monitoring system from Arizona Instrument LLC is the system you need to solve your hydrogen sulfide monitoring problems. Designed to provide long-term monitoring even in extreme weather conditions, it can be stationed at any location. Multiple units can be linked to form a perimeter monitoring system. Data logging and radio telemetry capabilities make downloading data convenient and easy from a remote PC
Unattended: The 651 is designed for set-and-forget hydrogen sulfide monitoring, inside or out.
Flexible: A detachable hand-held hydrogen sulfide analyzer is contained within the unit for pinpointing a gas source.
Smart Alarms: Define alarm points that meet your needs and receive email notifications and warnings.
Wireless: Measurement data is transmitted wirelessly from 651 stations to the user’s PC.
Rugged: The 651 is housed in a steel casing, insulated, air-conditioned, and ready for nearly any environment.
Features and Benefits
Perimeter Monitoring: Multiple Jerome® 651 units can be linked to form a perimeter monitoring system to help locate the source of H2S and ensure safety and compliance.
Detachable Unit: Quickly and easily sweep an area for hydrogen sulfide hot spots with the detachable, hand-held Jerome® 631-X hydrogen sulfide analyzer.
Gold Film Sensor: Validated in the field and in the lab for over 35 years, our proprietary gold film sensor ensures repeatable results across a wide range of applications.
Weather Station: An attached weather station monitors outside temperature as well as wind speed and direction for increased accuracy in pinpointing the source of odor contamination.
Data Transmission: Advanced data logging and radio telemetry capabilities make downloading data to a remote PC easy and convenient.
PC Software: Intuitive PC software with user-selectable time-weighted average reporting and a site view tab give users a bird’s eye view of the monitoring system as a whole.
Programmable Alarms: The 651 comes with programmable alarms that automatically send email alerts if your H2S levels rise above your specified upper limit.
Temperature Controlled Interior: Resistive heating and thermoelectric cooling keep the interior of the 651 at a consistent temperature for increased accuracy.
Regulatory Compliance: The 651 is in active use by many regulatory agencies and landfills, water treatment, and wastewater management facilities across the world.
