Features of Jerome 451
Perimeter Monitoring: Multiple Jerome® 451 units can be linked to form a perimeter monitoring system to help locate the source of mercury contamination and ensure safety and compliance.
Detachable Unit: Quickly and easily sweep an area for mercury hot spots with the detachable, hand-held Jerome® 431-X mercury vapor 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: The attached weather station monitors outside temperature as well as wind speed and direction for increased accuracy in pinpointing the source of mercury 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 451 comes with programmable alarms that automatically send email alerts if your mercury levels rise above your specified upper limit.
Temperature Controlled Interior: Resistive heating and thermoelectric cooling keep the interior of the 451 at a consistent temperature for increased accuracy.
Regulatory Compliance: The 451 meets and exceeds OSHA, NIOSH, ACGIH and MSHA action levels, making it ideal for monitoring mercury levels in high-risk areas, such as in industrial hygiene and mining.
