0.2 General Notes
This measuring device fulfils the requirements of the applicable
European and national directives (2004/108/EC) and standards
(EN61010). Appropriate declarations and documentation are held
by the manufacturer. To ensure trouble-free operation of the
measuring device and operational reliability, the user must carefully
read the operating instructions. The measuring device may only be
operated under the climatic conditions specified. These conditions
can be found in Chapter 3.1 "Technical data". This measuring
device may likewise only be used under the conditions and for the
purposes it was designed for. Operational reliability and
functionality are no longer ensured if the device is modified or
adapted. Gann Mess- u. Regeltechnik GmbH is not liable for any
damage arising from such modifications or adaptations. The risk is
borne by the user alone.
Laser equipment warning:
This unit is equipped with a Class 2 laser. Never
direct this laser beam into the eyes, neither directly
nor indirectly through reflecting surfaces.
Laser radiation may cause irreversible damage to
the eyes. When measurements are performed with
humans being nearby, the laser beam must be disabled.
The notes and tables in these instructions on permitted or
normal humidity conditions in practice and the general
definitions of terms have been taken from the specialist
literature. No responsibility can therefore be taken by the
manufacturer for the correctness of this information. The
conclusions to be drawn from the measurement results
are related to the individual conditions and the knowledge
drawn from professional experience for each user.

The measuring device may be operated in residential and
commercial areas, as the stricter class B for emitted
interference (EMC) has been adhered to.
The device may not be operated in the immediate area of
medical equipment (heart pacemakers, etc.).
The measuring device may only be properly used as
described in these instructions.
Keep the device and accessories out of the reach of
children!
Gann Mess- u. Regeltechnik GmbH accepts no liability for damage
resulting from non-adherence to the operating instructions or by not
taking proper care during transport, storage or operation of the
device, even if this requirement for care is not specifically
addressed in the operating instructions.
0.3 WEEE Directive 2002/96/EC Law on Electrical
and Electronic Equipment
Disposal of packaging, battery, and device must be undertaken in
accordance with the legal requirements at a recycling centre.
The device was manufactured after 1 May, 2010.

1 Introduction
1.1 Description
The Hydromette BL Compact TF-IR is a precise thermo-hygrometer
that is fitted with an IR surface temperature sensor and may be
used for various applications such as surveillance of residential
space, air conditioning systems, print shops, warehouses, etc.
Additional features included: single-handed operation, built-in
measurement probes, and a 3-line LCD for simultaneous display of
three measured values, e. g. air humidity, dew point temperature,
and surface temperature.
This combination of the different measuring techniques enables the
BL Compact TF-IR unit to be used for quickly and reliably
assessing dew point undershoots or determining borderline
conditions on surfaces such as walls, ceilings, floors as well as on
window or door lintels.
In addition to displaying the measured value, the unit creates an
audible signal when a critical surface temperature is located.
When using the unit in due time, mildew formation may be
prevented and occurrence of moistening caused by condensation
may be assessed reliably.
