Gold Film Hydrogen Sulfide Analyzer 

The newest H2S analyzer from AMETEK Brookfield is the Jerome® J605 Hydrogen Sulfide Analyzer. The Jerome® J605 can read as low as 3ppb with an incredible resolution of 20ppt. The J605 is housed in a light and ergonomically designed case, setting a new precedent for low-level, portable monitors. The industry-proven, gold film sensor has been upgraded and improved from previous models, resulting in longer life expectancies. 

  • Ultra-Sensitive: Detect hydrogen sulfide in the air at levels as low as 3 parts per billion (3ppb).
  • Proven: Jerome’s gold film sensing technology has been validated in the laboratory and in the field for more than 35 years.
  • Rugged: Its sturdy metal housing makes the J605 tough enough for nearly any environment.
  • Reliable: With 18 hours of battery life per charge, the J605 is always ready when you need it.
  • Smart: Features onboard data logging for up to 20,000 measurements, USB data transfer, and SCADA interface capabilities through 4-20ma output.

Features and Benefits

  • Ultra Low-Level Detection: The Jerome J605 can detect H2S in air at levels as low as 3 parts per billion (ppb) with a resolution of 20 parts per trillion (ppt).
  • 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.
  • Versatile: With a detection range of 3 ppb to 10 ppm, the J605 is ideal for a variety of applications, including regulatory compliance and odor control at wastewater and landfill facilities, scrubber efficiency testing and monitoring corrosion in control rooms, among others.
  • Regulatory Compliance: The J605 is in active use by many regulatory agencies and landfill, water treatment and waste management facilities across the world.
  • Data Logging: The integrated data logging system of the J605 can store data for up to 20,000 samples, including date, time and up to 80 locations.
  • Survey Mode: While in survey mode, the J605 continuously draws in samples of air to help users sweep an area for hydrogen sulfide hot spots and enable corrective action to be taken.
  • Field Regeneration: The J605 boasts a battery life of 18 hours and offers battery powered sensor regeneration that can be performed wherever and whenever you need it, allowing for extended testing in the field.
  • Rugged Construction: Housed in a light, ergonomically designed, durable metal casing, the J605 sets a new precedent for portable, low-level H2S monitors.
  • Intuitive Interface: The J605 offers simple, menu-driven operation as well as easy-to-understand diagnostics and error detection. It does not require PC software and comes with a USB interface for easy data transfer.
