Jerome J405 mercury vapor meter including required filter rental from NEDLABRental code: NLAA4250
The Jerome J405 is a specialized mercury vapor meter for real-time measurement of mercury vapor concentrations in air. This meter is used in situations that require fast, reliable and accurate determination of hazardous mercury vapor concentrations.
Mercury has a very low limit value. This is precisely why it is important to work with an analyzer that is sensitive, stable and suitable for field measurements. The Jerome J405 features a gold filter, which confirms in real time during the measurement whether the detected concentration is actually mercury vapor. This makes this meter particularly suitable for safety and environmental applications.
When do you deploy the Jerome J405?
The Jerome J405 is used in situations where mercury vapor needs to be quickly detected, assessed or controlled.
When a broken thermometer, barometer, fluorescent lamp or industrial spill occurs, you want to know immediately if hazardous concentrations of mercury vapor are present. The Jerome J405 responds within seconds and helps locate the source quickly.
During or after a mercury cleanup, it is important to check whether an area can be safely used again. Thanks to its low detection limit, this meter is suitable for reliably assessing even low residual concentrations.
In workshops, laboratories, recycling plants, waste treatment and manufacturing environments where mercury may be released, the Jerome J405 helps monitor air quality and protect employees.
This meter can also be used for air quality measurements around plants, chimneys, waste depots or locations with historical mercury pollution.


Practical explanations
The Jerome J405 is designed for professionals seeking a reliable and immediately deployable solution for measuring mercury vapor in air. These include higher safety professionals, occupational hygienists, occupational health physicians, environmental labs, remediation companies, incident response parties and companies in the chemical, waste treatment and oil and gas industries, among others.
Because this type of equipment is specialized and often used on a project basis, rental is a logical choice in many cases. You then have professional measuring equipment without high purchase costs, maintenance or downtime.
