1 Analyzer description
1.1 Purpose and applications
The Hygrovision mini is a compact analyzer designed to measure the dew points of wa-
ter and hydrocarbons.
This portable hygrometer (hereafter also analyzer) is an instrument that is designed to
directly measure dew point temperatures by means of a temperature-controlled mirror.
Hygrovision mini areas of application:
⇒Spot check measurements in the field
⇒Check the operational performance of permanently installed Hygrometers
⇒Confirm previous measurement results
⇒Regularly measure water and hydrocarbon dew points directly in locations that are
not equipped with automatic through-flow hygrometers or where no such instruments
can be permanently installed.
⇒Monitor various products as well as working and manufacturing processes (for exam-
ple, drying and vacuuming of facilities, systems, damp presses, steamers, regenera-
tors, evacuators, etc.)
Hygrovision analyzers can be used in a variety of sectors including the gas, oil and chemical
industries, metallurgy, power generation, instrument engineering and many other fields, in
order to provide quality control of production processes where water and hydrocarbon dew
point values are of relevance.
The analyzer is certified “explosion-proof” as defined by EN 60079-0:2009 and it has a
“flameproof enclosure” in accordance with EN 60079-1:2007. The Hygrovision mini has
an “intrinsically safe power circuit” as per EN 60079-11:2007 and is labelled II 2G
Exd [ib] IIB+H2 Т5.The analyzer can be deployed in designated explosion risk areas of
indoor and outdoor installations in accordance with EN 60079-14:2008 and in other ex-
plosive areas where the use of electrical equipment is controlled by regulation.

1.3 Measurement principle
The Hygrovision mini analyzer registers the dew point of water or hydrocarbons in a
gaseous mixture according to the principle of direct measurement, utilizing a mirror that
can be heated and cooled.
The measurement process involves monitoring the surface of the mirror and noting the tem-
perature at the moment condensation forms on its surface.
In addition, the observation process is enhanced by the availability of two different light-
ing systems for illuminating the dielectric condensation mirror.
During the measurement cycle the reflectivity of the mirror is monitored. When the dew
point is reached reflectivity decreases as a condensation film forms. The temperature
(T) at which this happens is the dew point.
The analyzer is equipped with an achromatic 40-power microscope for observing the
surface condition of the mirror. In addition, there are two options for illuminating the
mirror: vertical and side lighting.
•Vertical lighting can be used for the visual registration of the water and hydro-
carbon dew points.
•Side lighting is used specifically for the visual registration (confirmation) of the
dew point of water only.
The low angle of this illumination increases the optical intensity created by the scatter-
ing of light rays striking water condensation. This effect makes it possible to register
condensation earlier and with absolute clarity.
The mini is outfitted with a button pad that serves as the control interface. For example, it is
used to manually switch between lighting systems during the measurement process and to
regulate the mirror temperature. The temperature at which a clear condensation film forms
on the mirror’s surface is also fixed using this button keypad.
1.4 Construction
The Hygrovision mini analyzer has an explosion-proof design. For more information
about explosion proofing see point 1.8.
The analyzer consists of a cold body housing, a high-pressure gas delivery system,
and an optical system.
The optical system includes a microscope and two lighting elements: one mounted
perpendicular to the mirror and one at a low angle.
The housing body of the analyzer includes an electronics unit and a measurement
cell. In order to support autarkic operations, the body of the mini includes a battery
compartment designed for the mini’s rechargeable battery.
The measurement cell, the gas delivery system, and the microscope, combined form
the measurement chamber. The measurement chamber is designed to accommodate
a working pressure of 100 bar.

7
The measurement cell includes the temperature-controlled condensation mirror, which
has an integrated thermal sensor, a thermoelectric battery, and a light emitting diode
for providing the side illumination.
The gas delivery system guides the sample gas over the temperature-controlled mir-
ror in the measurement cell. This system includes a small observation window for
monitoring the condensation process and a particle filter to protect against contamina-
tion.
The microscope is mounted directly onto the gas delivery system. The vertical lighting
system is integrated into the microscope.
The electronics unit is made up of the liquid crystal display, the replaceable power
source (battery), and a four-button control unit (button pad). Via the four-button control
pad, the electronics unit makes it possible for the Hygrovision mini user to control how
rapidly the condensation mirror is cooled and heated. The button pad is also used to
turn the analyzer on and off,select the illumination system, and enter other operating
commands.
Data from the last measurement as well as system information are shown on the Liq-
uid Crystal Display (LCD).
A charging unit is delivered with the analyzer for recharging the battery .
