Features and Benefits

• Ultra-Sensitive Detection: The Jerome® 631-X detects hydrogen sulfide (H2S) in air at levels as low as 3 parts per billion (ppb), with a detection range of 0.003 ppm to 50 ppm. This makes it ideal for regulatory compliance, odor control monitoring, scrubber efficiency testing, and corrosion monitoring in control rooms.
• Proven Gold Film Sensor: The proprietary gold film sensing technology has been validated both in the laboratory and the field for over 35 years, ensuring repeatable and reliable results across a wide range of applications.
• Rugged Construction: Built with a sturdy metal housing, the 631-X is designed to withstand tough environments, providing durability and reliable performance whether in the lab or in the field.
• Easy Operation: The 631-X is simple to use, offering accurate hydrogen sulfide readings at the touch of a button. The quick reference guide beneath the handle and the easy-to-read display with automatic backlight make day-to-day operation straightforward, even in low-light conditions.
• Survey Mode: Continuously draw in air samples to sweep an area for hydrogen sulfide hot spots, enabling quick identification and corrective action.
• Optional Data Logging: The 631-X can be equipped with a data logger module capable of storing up to 1,000 measurements, including date and time, for easy tracking and analysis.
• Optional Autosample Mode: Program the 631-X to take samples at intervals ranging from 1 to 60 minutes, allowing for continuous monitoring without manual intervention.
• Field Regeneration: Extend testing capabilities on-location with the option to perform sensor regeneration in the field using the Power Inverter Kit, ensuring the instrument is always ready for use.
