7. Description

7.1 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.

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.
