1 Introduction
1.1 Description
The Hydromette BL UNI 11 is a universal triple meter with a 3-line LCD
display. By connecting a wide range of active electrodes and TF sticks with
high-quality sensor technology, the measurement ranges of building moisture,
humidity and temperature can be covered.
The Auto Sensor Technology used enables the BL UNI 11 to automatically
detect the electrode or TF stick connected and to adapt the measured value
readout to the respective sensor type. If a TF stick (either directly or using the
MK 18 cable) and another electrode (e.g. B 55 BL) are connected at the same
time, the meter will always show the measuring values obtained with the TF
stick.
The following BL active electrodes can be connected to the BL UNI 11:
Active electrode B 55 BL
Probe for non-destructive location of moisture concentration in
construction materials of all kinds and moisture distribution in walls,
ceilings and floors
Active electrode RF-T 28 BL
Probe for measuring the climate within seconds
Active electrode RF-T 37 BL
Probe for rapid measurement of air humidity and temperature
TF stick 16 K-21, TF stick 16 K-25, TF stick 16 K-25 M,
TF stick 16 K-25 P
TF sticks for rapid measurement of air humidity and temperature
Active electrode TF-IR BL
Probe for the measurement of climate as well as infrared surface
temperature
Active electrode ET 10 BL
Surface temperature sensor
Active electrode OT 100 BL
Push-in electrode for measurements in solids, bulk materials and
fluids

Index and material symbol
A measurement process is started by pressing the Mbutton.
The 0 type index for a measurement is shown in Digits. The scale is in the
range of 0 to 100. %-sign and material indexl will disappear. This value allows
individual measurements or complete humidity profiles to be created,
irrespective of the properties of the material to be measured.
Digit values are non-dimensional measured values and no real humidity
values in %!
A measurement is initiated by pressing the Mbutton for more than 1 second.

2.3 Setting Menus
From the measuring menu, repeatedly press the Up or Down button to select
the following menu items one after another (use Down to select the menus in
their order, use Up to select them in opposite order).
1. Measurement menu (main menu): Use to carry out the measuring
process.
2. Material setting: Use to select the material type.
3. Maximum value display: The highest value measured is shown here.
4. Minimum value display: The lowest value measured is shown here.
5. Memory menu: The last 5 values measured can be called here.
2.3.1 Measurement Menu (Main Menu)
The last measurement with the note "Hold" is shown here. The current type is
shown in the last line of the display. When an external temperature sensor is
connected, the sensor temperature is shown in the middle line of the display.
In this menu, a new measurement can be started by pressing the "M" button.
During the measuring process, the "Hold" symbol disappears from the
display. After releasing the "M" button, the measured value is saved. The
"Hold" symbol is displayed again.
If the new measured value is larger than the previous maximum value, "Max"
flashes on the display. If the value is not to be saved, the "M" button must be
pressed briefly. If the value is to be saved, a new measurement is started with
a long press on the "M" button without changing the previous maximum
values.

momentarily pressing the "M" button (measurement button).
The value flashes and can now be deleted using a long press on the "M"
button.
Afterwards, only the "Max" symbol is still flashing. Using another momentary
press on "M" button, the entry is confirmed and the device returns to the
Ready mode.
Using the "M" button, a new measurement can then be carried out
immediately.

momentarily pressing the "M" button.
The value and the % symbol now flash and the value can be deleted by a long
press on the "M" button. After deleting the value, only the % symbol still
flashes. By momentarily pressing the "M" button again, the deletion of the
value is confirmed and the % symbol disappears. The device now returns to

2.3.5 Memory Menu
Symbol: memory "r1"
As soon as you select the memory menu, the memory location number "r1" is
displayed for approx. 1 second, and then the last measured saved value
contained there is displayed.
The last 5 measured values are automatically saved and stored in memory
locations "r1" to "r5". The last measured value is in memory location "r1". This
is a ring buffer: Once the sixth measured value is recorded, the first measured
value is automatically removed from the memory.
By momentarily pressing the "M" button, the next memory location "r2" is
selected and the value contained there is displayed. After reaching the 5th
memory location, the first one is shown again.
The saved values displayed can be identified by the fact that no "Hold"
symbol is shown in the display.

Structural moisture Temperature Air humidity
4.2 General Notes
The BL UNI 11 is an electronic multi-purpose meter for three measured
values, to which a number of GANN BL electrodes and TF sticks can be
connected. The Auto Sensor Technology used enables the BL UNI 11 to
automatically detect the electrode or TF stick connected and to adapt the
measured value readout to the respective sensor type. A 3-line LCD display
for the detection of moisture, humidity and temperature is used.
If no active electrode is connected, “InP Sen” appears on the device. The
various active electrodes and TF sticks are adapted to the different areas of
application and can be changed arbitrarily and easily. If a TF stick (either
directly or using the MK 18 cable) and another electrode (e.g. B 55 BL) are
connected at the same time, the meter will always show the measuring values
obtained with the TF stick.
4.2.1 Active electrode B 55 BL
The active electrode B 55 BL is an
electronic moisture meter of the dielectric
constant / high frequency measuring
principle. It has an integrated measuring
circuit, designed for non-destructive
location of moisture concentration in
construction materials of all kinds and
moisture distribution in walls, ceilings and
floors.
An ideal pretester for use with all "CM"
devices.

Hydromette BL UNI 11
4.2.2 Active electrode RF-T 28 BL
The active electrode RF-T 28 BL is a
precise thermo-hygrometer for many
application areas, for example living
space surveillance, air-conditioning
technology, printeries and warehouses.
Additional features include: the
immediate display and calculation of
relative humidity, air and dew point
temperatures on the 3-line LCD display
of the main unit.
4.2.3 Active electrode RH-T 37 BL
The active electrode RH-T 37 BL is a
precise thermo-hygrometer for rapid
measurement of relative humidity and
air temperature. Using hardcoded
sorption isotherm, weight and
percentages by mass can be
determined for various building and
insulation materials as well as hard and
soft wood.
The model “flex” has a flexible sensor
tube and is therefore suitable for
measurements in places that are hard
to reach.
The RH-T 37 BL is particularly suitable for moisture analysis, damage
assessments, construction-dehydration and to test the readiness for the
installation of floor and wall coverings.
