  • Page 3: Construction

    The handheld microwave moisture meter MOIST 350 B was designed for non- destructive moisture measurements in various building materials. In its basic configuration it consists of a microcontroller based handheld with colour display and sensing heads. More moisture probes, a RH humidity probe, a penetration applicator MOIST-ENDO and software MOISTANALYZE are available optionally.

    Warning: The included accumulator is not designated to be changed by the end user. If the accumulator can not be charged anymore (after app. 1000 cycles) you have to send the handheld to hf sensor. Keyboard layout <ON/OFF>-Button: Turns the device on/off.

  • Page 9: Initial Operation

    Initial operation Power supply The device is designed to be used with the enclosed power supply as well as the included accumulator for independent operation. Please turn off the device before you plug in the power supply. The charge indicator is calibrated for the original accumulator. The use of other types of accumulator can destroy the device but at least causes wrong information about the charge state.

    Mostly no sensor head is connected or the head has been changed during the on-state of the device. A reset of the handheld (turn off and on) will relieve the failure. The handheld will be turned on by pressing the button <ON/OFF>. Depending on the mode the main menu will be displayed or the screen for download to PC.

  • Page 24: Measurements With The Meter

    Measurements with the meter The basic configuration of the MOIST 350 consists of the handheld and the sensing heads MOIST-PM V2 and MOIST-R1M V2(see title). For doing measurements some special features of the microwave method have to be kept in mind, which are described in the following chapter. Basics of Dielectric Moisture Measurements The microwave method is a dielectric moisture measurement method.

  • Page 25: Microwave Moisture Measurements

    Microwave Moisture Measurements When the frequency is rising (in the microwave region) the polarization of the water molecule becomes more and more difficult because of internal binding forces (the water molecule „swims“ in the water and is bound to the other molecules). The microwave field causes an internal friction in the material, which can also be called dielectric loss.

  • Page 26: Moist-Method And It's Special Features

    To transform the advantages of microwave moisture measurements described in the previous chapter in a useful format, hf sensor developed two sensing heads, which are only to be put onto the material: MOIST-R1M V2 as a surface sensing head and MOIST-PM V2 as volume sensing head.
  • Page 27 Moisture measurement with the surface sensing head MOIST-R1M V2 is also possible in objects with lower thickness. Before doing such a measurement hf sensor must be consulted, because usually for such measurements special arrangements must be used. < 1 cm...
  • Page 28 In principle moisture measurement with the surface sensing head MOIST-R1M V2 is also possible when the distance to lateral bounds of the test object is lower. Before doing such a measurement hf sensor must be consulted, because usually for such measurements special arrangements must be used.
  • Page 29 Surface Roughness and Tipping Because of the higher penetration depth the influence of surface roughness is not as high as for the surface sensing head MOIST-R1M V2. For measurements at surfaces with ledges or holes deeper than 5 mm average values must be generated from single measurements.
  • Page 30 Minimum Distance from lateral bounds The microwave field of the volume sensing head MOIST-PM V2 has significant lateral extent. Therefore a minimum distance from lateral bounds must be kept to avoid distortions of the measurement. Simplified the interaction volume can be considered as a cylinder of a radius of about 10 ...
  • Page 31 Material specific calibration and moisture index The sensing heads MOIST-PM V2 and MOIST-R1M V2 are material specific calibrated. The calibration curves were generated in the moisture laboratory of hf sensor very carefully. At the moment calibrations are available for these materials: - Brickwork new (density 1.6 ...
