Jerome® 631-X

H2S Analyzer

Gold Film Hydrogen Sulfide Analyzer

The portable Jerome® 631-X Hydrogen Sulfide Analyzer displays low-level concentrations in just seconds. It offers an analysis range of 0.003-50 ppm for odor and corrosion control, safety, and leak detection in such industries as wastewater treatment, oil and gas, pulp and paper, and farming. This simple-to-use instrument utilizes an internal rechargeable battery pack or AC power, and is easily carried to suspected sources of hydrogen sulfide for detection and measurement. Locked in survey mode, the 631-X automatically displays hydrogen sulfide concentrations as quickly as every 3 seconds.

OVERVIEW

Ultra Sensitive

Detect hydrogen sulfide in air at levels as low as 3 parts per billion (3ppb).

Rugged

Sturdy metal housing and solid-state design make the 631-X tough enough for nearly any environment.

Proven

The Jerome’s gold film sensing technology has been validated in the laboratory and in the field for more than 35 years.

Simple to Operate

Get an accurate hydrogen sulfide reading at the touch of a button.

Data Logging

The available data logger module can store up to 1,000 measurements

FEATURES

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, and monitoring corrosion in control rooms, among others.

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.

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.

Regulatory Compliance: The 631-X is in active use by many regulatory agencies and landfill, water treatment and waste management facilities across the world.

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: The 631-X can perform sensor regeneration in the field when used with the optional AZI Power Inverter Kit, allowing for extended on-location testing
