• Ultra Low-Level Detection：The Jerome J405 can detect mercury in air at levels as low as 0.5 µg/m³ with a resolution of 0.01 µg/m³.
• 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：The J405 is in active use by many environmental agencies, industrial hygienists, miners and first response teams across the world.
• Regulatory Compliance：With a lower detection limit of 0.5 µg/m³, the J405 meets and exceeds EPA and ATSDR standards for industrial and residential remediation actions as well as OSHA, NIOSH, ACGIH and MSHA action levels.
• Optional Data Logging：When equipped with data logging capabilities, the J405 can store data for up to 20,000 samples including date, time and location.
• Survey Mode：While in survey mode, the J405 continuously draws in samples of air in order to help locate the source of mercury contamination and allow corrective action to be taken.
• Field Regeneration：The J405 boasts a battery life of 24 hours and offers battery powered sensor regeneration that can be performed wherever and whenever you need it, allowing for extended testing in the field.
• Durable：Housed in a light, ergonomically designed, durable metal casing, the J405 sets a new precedent for portable, low-level mercury monitors.
• Intuitive Interface：The J405 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.
