6. Description
6.1. General
Each HERMetic instrument is
individually
identified
with a 6 digits serial number starting
with the letter G, example G10058. This serial
number is printed on the identification plate as
shown on Figure 7-1.
The HERMetic instrument is fitted with an
ULTRA
sensing probe.
The unit emits control beep, continuous beep and
intermittent beep.
When the sensing probe is surrounded by air, a
control beep occurs every 2 sec.
When the sensing probe is in contact with any
petroleum product, the beep is continuous.
When the sensing probe is in contact with water
the beep is intermittent.
Control beep
• •
Continuous beep

Intermittent beep
• • • • • •
A light signal (LED) can also be activated that
blinks at the same frequency as the buzzer tones.
This can be useful in noisy environments or at
night.
A backlight can be used at night to light up the
display.
The HERMetic instrument is powered by a 9 Volt
battery stored in the electronic terminal named
instrument unit. Current consumption is very low,
ensuring long operation without battery
replacement.
A continuous tone means that the
battery needs replacement
. If the battery power
is too low, it is no more possible to read the
temperature.
Maintenance is easy
because design is modular
and allows quick exchange of parts.
