Hydromette also has an IR surface temperature sensor. 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.
Information Specific warnings CAUTION: The Hydromette BL Compact TF-IR 2 uses a laser in laser class 2 according to IEC 60825-1. People can be blinded by the laser. The laser must never be directed at people or animals. Do not look directly into the laser beam and avoid reflections on reflective surfaces.
General safety instructions It must be ensured that the complete instructions and all safety instructions have been read and understood before using this device. All instructions must be followed.

All safety information and instructions must be kept for future reference and passed on to subsequent users of the product.
1.6.2 Preparation and start-up Never store or place the device where it can fall or be drawn into water or other liquids. To avoid the risk of electric shock, never immerse the device in water or other liquids. Always remove all packaging before operating the device. Fire hazard! Do not use a damaged device.
1.6.4 Maintenance and inspection Remove the battery before cleaning the product. Do not use abrasive cleaning cloths or chemicals to clean the product as these can damage the surface. CAUTION Stop using the product in the case of visible damage, strong odour development or excessive overheating of components.

displayed. The measuring mode selection is designed as a ring menu, whereby the setting modes are scrolled through in the following order by pressing the "Up" button. Measuring mode "Dew point IR" (rh / lr / dp): The relative humidity (in r.h.%), the measured IR surface temperature (in °C) and the dew point temperature (Dp in °C) are displayed.

The device is delivered with an emission factor of 95 as a factory setting. If the default settings for emissivity (EM factor) and/or the laser pointer should be changed, press the "M" button briefly (< 1 second). Emissivity (EM factor) and laser pointer display now start flashing. EM factor adjustment: The emissivity (EM factor) can now be set between 20% and 100% in steps of 1 using the "Up"...
Using the "M" button, a new measurement can then be carried out immediately. 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 displayed.
5.3.6 Memory Menu Measuring Press Down button 5 Menu times As soon as the memory menu is selected, the ring memory symbol "o" and the associated memory location number "1", i.e. "o1", are displayed for approx. 2 seconds. The last measured memory value it contains is then displayed automatically.
6 Other Functions 6.1 Use without TF-Stick It is also possible to perform measurements with the Hydromette BL Compact TF-IR 2 without a TF- Stick inserted. The infrared sensor integrated in the device works independently. This ensures that surface temperature measurements are possible at all times.
6.2 Automatic switch-off If no button is pressed within approx. 90 seconds, the device switches off automatically. The current values are retained and are displayed again after the device is switched on again. 6.3 Battery monitoring If the battery symbol is shown in the display, the battery is dead and must be replaced.

9 Application Notes 9.1 Using the Hydromette BL Compact TF-IR 2 For particularly precise measurements, especially at temperatures below room temperature (20 - 25 °C) or if there are significant temperature differences between the intrinsic temperature of the measuring instrument and the ambient climate, the device should be exposed to the ambient climate for approx.
9.3 Equilibrium wood moisture content (EMC) Equilibrium wood moisture content is the moisture content adopted by the wood when it is exposed to constant climate (constant humidity and constant temperature) for sufficiently long time. The device can simultaneously display relative humidity, temperature, and equilibrium wood moisture content.
9.6 Measuring using infrared temperature measurement technology (IR) 9.6.1 General All bodies with a temperature above "absolute zero" (= 0 °K or -273 °C) emit infrared radiation, also known as thermal radiation. The intensity of this thermal radiation, taking into account the emissivity, is considered a measure of the surface temperature.
9.6.3 Emissivity The Hydromette BL Compact TF-IR 2 provides manual emissivity adjustment in the range of 20% to 100%. An emissivity table can be found in the Appendix. The measuring instrument is set to a default emissivity of 95%. This value applies to most building materials, plastics, textiles, papers and non-metallic surfaces.
9.6.4 Measurement spot size The measurement spot diameter depends on the distance and is 5 mm immediately before the probe opening. By increasing the distance (A) of the measuring instrument from the object to be measured, the measuring spot diameter (D) increases proportionally in the ratio of approx. 6:1. With a distance (A) of 250 mm, the measurement spot diameter (D) is 46 mm.
