Gold Film Mercury Vapor Analyzer

The Jerome® 431 mercury vapor analyzer uses a patented 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.

Features & Benefits

  • 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, and mercury exclusion testing, among others.
  • Gold Film Sensor: The 431-X features an inherently stable gold film sensor with an advanced microprocessor that ensures a linear response throughout the entire range of the sensor.
  • Rugged Construction: Housed in a sturdy metal case, the 431-X is built to withstand rough operating conditions and deliver accurate results 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.
  • 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.
  • 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.
  • 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.
  • 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: The 431-X can perform sensor regeneration in the field when used with the optional AZI Power Inverter Kit, allowing for extended on-location testing.
