Low-Level Detection: The Jerome® 631-X can detect H2S in air from 0.003 ppm to 50 ppm, making it ideal for regulatory compliance and odor control monitoring, scrubber efficiency testing, monitoring corrosion in control rooms, 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 631-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 helps simplify 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 631-X is in active use by many regulatory agencies and landfill, water treatment and waste management facilities across the world.
Survey Mode: The 631-X features a survey mode that allows the user to continuously draw in samples of air in order to sweep an area for hydrogen sulfide hot spots and enable corrective action to be taken.
Optional Data Logging: When equipped with data logging capabilities, the 631-X can store data for up to 1,000 samples, including date and time.
Optional Autosample Mode: The 631-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 631-X can be performed in the field using the optional Power Inverter Kit, allowing for extended on-location testing.
