Description
The Mercury Vapour Indicator (MVI) is a compact, self contained and completely portable instrument which indicates
the amounts of Mercury in micrograms/cubic metre.
The indicating digital display and carrying handle are mounted on the top cover. A female Luer connector is provided
at the end of the instrument to accommodate a dust and water trap filter with PTFE extension probe. In addition, a
length of flexible tubing may be connected to the filter for greater convenience when checking floor areas or gratings.
The internal Nickel Metal Hydride battery is rechargeable using a plug-in battery charger. The operating time when
fully charged is greater than >4.5 hours. Warm up time is approximately 10 minutes and direct readings are indicated
on an easy to read LCD display.
The audible alarm provides warning of three pre-defined conditions:
Condition
1.
Mercury vapour concentration greater than 20 µg/m
2.
Negative reading from -20 to -25 µg/m
3.
Low battery
The audible alarm is inhibited during the first 5 minutes of operation.
