Features Mercury Vapor Analyzer Jerome® 431-X
Low-Level Detection: The Jerome® 431-X can detect mercury vapor in air from 0.003 mg/m3 to 0.999 mg/m3, making it ideal for industrial hygiene monitoring, mercury spill detection and cleanup, mercury exclusion testing and more.
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.
Rugged Construction: Housed in a sturdy metal case, the 431-X is built to withstand rough operating conditions and deliver accurate results whether it is in the field or in the lab.
Easy to Use: The quick reference guide beneath the handle simplifies day-to-day use and the easy to read display screen is equipped with an automatic backlight that activates in low-light situations.
Regulatory Compliance: The 431-X meets and exceeds OSHA, NIOSH, ACGIH and MSHA action levels and is in active use by many environmental agencies, industrial hygienists, miners and first response teams across the world.
Survey Mode: The 431-X features a survey mode that allows the user to continuously draw in samples of air in order to sweep an area for mercury vapor hot spots and enable corrective action to be taken.
Optional Data Logging: When equipped with data logging capabilities, the 431-X can store data for up to 1,000 samples, including date and time.
Optional Autosample Mode: The 431-X offers an optional autosample mode that can be programmed to take a sample at various intervals between 1 and 60 minutes.
Field Regeneration: Sensor regeneration for the 431-X can be performed in the field using the optional Power Inverter Kit, allowing for extended on-location testing.

The Jerome® J505 Mercury Vapor Analyzer is a portable fluorescence spectroscopy analyzer, which allows the detection cell to be simpler, smaller, lighter weight and more durable than competing spectroscopy instruments. The highly efficient optical cell requires less flow to purge the system, allowing the J505 to run at a lower flow rate minimizing sample dilution as found in competing spectroscopy instruments.
The Jerome® J405 portable mercury vapor monitor is redefining the portable mercury vapor analyzer market. Significant performance enhancements and modern communications capabilities have been combined to create a new option for mercury spill detection and clean-up analysis. The J405 utilizes the industry-proven, inherently stable and reliable gold film sensor technology and simple, one-button operation. The ergonomically-designed handle, lighter exterior case and significantly lower detection capabilities (0.5 µg/m3) make it a portable, easy to use, low-level mercury detection instrument.
The Jerome® 431-X mercury vapor analyzer uses our proprietary gold film sensor for accurate detection and measurement of toxic mercury concerns for applications such as industrial hygiene monitoring, mercury spill clean up and mercury exclusion testing. Simple push-button operation allows users to measure mercury levels from 0.003 to 0.999 mg/m3 in just seconds.
