Jerome 431-XE Mercury Vapour Analyser with RS232 Comms |
|
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. |

Technical Notes:-
This instrument should not be allowed to ingest
liquids as these can cause serious damage, especially to the sensor. Sensor
regeneration* should be performed at the start of a day’s monitoring
and again at the end. Sensor regeneration should be performed at an interval
of no more than 30 days.(mains power required). A clean power source 220-240V
50/60Hz is required.
