The Jerome® J405 portable Mercury vapour monitor is redefining the portable Mercury vapour analyser market. Significant performance enhancements and modern communication capabilities have been combined to create a new option for Mercury spill detection and cleanup analysis.
Like its 411 & 431X predecessors, the J405 utilises the industry-proven, inherently stable and reliable gold film sensor technology and simple, one-button operation. The ergonomically-designed handle, lighter exterior case and significantly lower detection capabilities (0.5 μg/m3) have reset the bar for portable and easy, low-level Mercury detection instrumentation.
The larger display, on-board data logging, auto zeroing, and battery-powered sensor regeneration will simplify operation and maintenance in the field. Menu-driven programming, USB data communications and SCADA compatibility via 4-20 ma output further enhance data retrieval, storage and reporting. |

| The Jerome 431-XE mercury vapour analyser
uses a patented gold film sensor for accurate detection
and measurement of toxic mercury vapour in the air.
This portable hand-held unit can easily be carried
to locations with mercury concerns for applications
such as industrial hygiene monitoring, mercury spill
clean up and mercury exclusion testing. Simple, push-button
operation allows users to measure mercury levels from
0.003 to 0.999 mg/m3 in seconds. |
 |
The gold film sensor
is inherently stable and selective to mercury, eliminating
interferences common to ultraviolet analysers, such
as water vapour and hydro-carbons. When the sample
cycle is activated, the internal pump in the 431-XE
draws a precise volume of air over the sensor. Mercury
in the sample is adsorbed and integrated by the
sensor, registering it as proportional change in
electrical resistance. The instrument computes the
concentration of mercury in milligrams per cubic
meter or nanograms, and displays the final result
in the LCD readout. An improved film regeneration
circuit in the 431-XE makes the sensor last even
longer than earlier models.
Additional accessories are available
to customise the Jerome 431-XE to meet individual
application needs. An optional communications configuration
allows data logging and computer interface capabilities.
For data acquisition during portable surveys, a
Jerome data logger plugs into the 431-XE. Using
the Jerome Communications (JCS) software, the analyser
and data logger download recorded data to the computer
for analysis, printout, and permanent record storage.
The JCS software can also program the instrument
for stand-alone monitoring. If the sensor becomes
saturated while the 431-XE is attached to the data
logger or computer, the analyser automatically regenerates
the sensor and then resumes sampling. They can also
be used as collection devices for applications such
as gas stream analysis. An internal option board
allows auto-zeroing, DC power operation, timed regeneration,
and timed sampling during prolonged unattended sampling
periods. The option board also allows external fresh
air solenoid support and 4-20 mA or 0-2 V analogue
output. A moulded hard carrying case or soft field
case give added versatility and organised storage
for the instrument and its accessories.
