4Description of the product
The Hydromette BL Compact TF-IR 2 is a precise thermo-hygrometer with infrared surface
temperature sensor for many applications, e.g. surveillance of residential spaces, air conditioning
systems, print shops, warehouses, etc. Further features are: Single-hand operation, integrated and
plug-in measuring probes, 3-line LCD display for simultaneous display of three measured values such
as humidity, dew point temperature and surface temperature.
This combination of different measuring methods enables the Hydromette BL Compact TF-IR 2 to
quickly and reliably assess dew point undershoots, or to detect borderline situations on surfaces such
as walls, ceilings, floors and window and balcony door lintels.
In addition to displaying the measured value, the device creates an audible signal when a critical
surface temperature is detected.
If used in good time, this can prevent mildew formation or reliably assess the occurrence of
condensation humidification.
The measuring probe is replaceable. Therefore, several measuring probes (plug-in TF-Sticks) can also
be attached to different measuring points, and these can be interrogated quickly one after the other
avoiding prolonged adjustment times.
The Hydromette BL Compact TF-IR 2 has a mini-USB port that can be used to download any firmware
updates using the GANN Dialog Pro PC software.
An internal memory is available for storing data.
The silicone buttons give haptic feedback for important functions.

The Hydromette BL Compact TF-IR 2 is supplied with the TF-Stick 16 K 25 inserted as standard.
If the device is now switched on by pressing the "On" button, the device starts in the "Dew point IR"
(rh / lr / dp) measuring mode.
If the TF-stick is not (correctly) inserted, the display "InP SEn" is shown
when the measuring button is pressed and held down for a long
time (>2 seconds)!

5.3 Setting menus
The following menu items can be selected one after the other by repeatedly pressing the "Down"
button.
1. Measuring Menu (main menu): The measurement process can be performed here
2. Measuring mode selection: The different measuring modes can be set here.
3. Laser Pointer / EM Menu: This menu can be used to disable/enable the laser pointer and to
set the emissivity (EM factor).
4. Maximum value display: The largest measured value is shown here.
5. Minimum value display: The smallest measured value is shown here.
6. Memory Menu: The last 5 measured values are stored here. The oldest value is overwritten
after each measurement.
The menu items are selected in reverse order by pressing the "Up" button.
Measuring Menu (main menu)5.3.1
After switching on, the device is in the Measuring Menu (main menu). The other menus can be
accessed from here by pressing the "Up" or "Down" buttons.
In the Measuring Menu, the last measured values are displayed according to the measuring mode
selection made with the associated units and the note "Hold".
Pressing and holding the "M" button (> 2 seconds) starts a new measurement, the measured values
adapt to the ambient climate. During the measuring process, the "Hold" symbol disappears from the
display. After releasing the "M" button, the measured value is held and automatically stored in the
ring memory. This overwrites the oldest stored value. 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 new value should be accepted, the "M" button must be pressed briefly (< 1 second). If the value
should not be saved, a new measurement can be started by pressing and holding (> 2 seconds) the
"M" button without changing the previous maximum value.
If the new measured value is smaller than the previous minimum value, "Min" flashes on the display.
If the new value should be accepted, the "M" button must be pressed briefly (< 1 second). If the value
should not be saved, a new measurement can be started by pressing and holding (> 2 seconds) the
"M" button without changing the previous minimum value.

Measuring mode selection5.3.2
The device is delivered with the measuring mode "Dew point IR"
(rh / lr / dp) as factory setting.
The device must be switched on and in the main measuring mode to be able to make the measuring
mode settings. Press the "Down" button once to access the measuring mode selection. If the setting
for the measuring mode should be changed now, the "M" button must be pressed briefly (< 1
second).
The measuring mode display flashes and can be set using the Up and Down buttons. The change is
saved by briefly (< 1 second) pressing the "M" button again.
After confirming the change, the display automatically jumps to the
measuring menu of the (newly) selected measuring mode. This removes
the values of the previous measuring mode from the display. Any stored
"Max" or "Min" values remain in the memory of the respective
measuring mode.
Now a new measurement can be performed by pressing and holding
(> 2 seconds) the "M" button
The Hydromette BL Compact TF-IR 2 has 7 different setting modes. The selected mode changes the
display of the measuring menu. Depending on the mode, the appropriate physical dimension is also
