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 6 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 Audible Signal

1. High Mercury vapour concentration greater than 20 µg/m

Slow pulse (1/sec)

2. Negative reading from -20 to -25 µg/m

and lower Continuous tone

3. Low battery Fast pulse (3/sec)

The audible alarm is inhibited during the first 5 minutes of operation.
