Measuring Moisture, Humidity and Condensation

Surveyors involved with identifying the causes of dampness in buildings may need to know the humidity and temperature levels in the building, as well as moisture levels in walls / floors. Effectively undertaking seven different types of readings:
1. Surface moisture content
2. Sub-surface moisture content
3. Relative humidity (%RH)
4. Ambient temperature
5. Surface temperature
6. Dew point temperature
7. Condensation

Unfortunately, the readings for moisture content and humidity are not the same. Worse still, they can not converted and require different types of instruments for each task.

If you require both moisture and humidity readings, then there is a simple solution.

Protimeter MMS
The Protimeter MMS (Moisture Measurement System) combines a moisture and humidity meters functionality into one system, effectively five instruments in one unit.

By utilising the operational modes of the Protimeter MMS, the operator can identify the scale and extent of a moisture problem. Establishing if it is due to condensation, rising dampness or lateral ingress. This leads to more thorough and reliable diagnosis.

1. Moisture Meter Modes
The Protimeter MMS may be used as a moisture meter in two operational modes. Measure mode uses pin-type electrodes for surface moisture and Search mode uses a radio frequency technology to provide moisture measurements beneath the surface.

2. Hygrometer Mode
The Protimeter MMS uses the interchangeable Hygrostick sensor to measure humidity and temperature. The Hygrostick may be connected directly into the Protimeter MMS instrument for measuring conditions in rooms and other environments or via an extension lead.

The facility makes the Protimeter MMS an ideal instrument to measure the Equilibrium Relative Humidity (ERH) of walls and floors using the Hygrosticks that have been placed into pre-drilled clearance holes or the humidity box for measuring ERH levels of floors.

3. Condensator Mode
The condensator mode is used for confirming the presence of condensation and risk assessment by comparing surface temperatures, with the dew point of the environment under investigation. When used with the surface temperature sensor the Protimeter MMS can make the following measurements:
- Relative humidity
- Ambient temperature
- Dew point
- Surface temperature
- Difference between surface temperature and dew point

Leica Roteo 35G - 400% More Visible

When undertaking levelling tasks over a large area, the beam of a red laser can be hard to see and will commonly require a detector eye to find the beam.

Alternatively a green beam laser level operates through a higher light range and is four times more visible to the human eye. With green beam laser levels, the laser beam provides better visibility in very bright conditions and over long distances.

Leica Geosystems have recently launched an enhanced interior laser level, the Leica Roteo 35G ‘Green Beam’. Providing all the characteristics of the very popular Leica Roteo 35, the new green beam option is the preferred choice for interior levelling tasks over long distances.

All-round perfection in every condition
On ceilings or walls, on the floor or on a tripod, the Leica Roteo 35G rotating laser is a multitalented performer. You can use it to work precisely on many indoor tasks in which levelling or aligning is required in very bright conditions and over very long distances.


400% More visibile
The pioneering green laser beam is four times more visible to the human eye. So you have the best possible visibility.






Installing ceilings and wallsWith its motorized wall mount, the Leica Roteo 35G can be positioned on the wall and moved effortless backwards and forwards using the combined remote control/detector unit, allowing you to quickly suspend ceilings and erect drywalls.

Marking out right angles
The Leica Roteo 35G is also a great help in the vertical plane. The combination of a vertical 360° reference plane and plumb beam simplifies layout, allowing you to work more accurately and efficiently on interior works.

Very VersatileThe integrated motorised wall mount, bright visible beam, horizontal and vertical lines or an exact 90° angle – it is no problem for the Leica Roteo 35. The rotating laser can automatically self-level for inclined set-ups of up to ± 4.5°. Scanning mode makes work easier by improving visibility in bright lighting conditions.

Motorised Wall MountThe Leica Roteo 35 laser level features a motorised wall mount, allowing for the instrument to move easily up and down when attached to the wall for ceiling grid installations. All operations can be controlled from the remote control and RRC350 laser detector eye.

HI AlertThe instruments H.I. (height of instrument) Alert system will sound an alarm if the laser is disturbed, stopping the head from rotating to prevent inaccurate readings.

Fugenex Damp Protect

Fugenex Damp Protect is a simple innovative method for measuring humidity through an irreversible humidity indicator.
The Fugenex Damp Protect indicators provide early warning signals of humidity and help to indicated if there is a condensation problem rather than a structural fault.

There are many ways to get an on-the spot account of the relative atmospheric humidity, however, there are few ways of easily measuring the relative humidity over a period of time, i.e. how long something has been exposed to humidity above a certain level.


Fugenex Damp Protect sensors, provide a physical-chemical principle, show how long the relative humidity has exceeded a predetermined level. The reading on the indicator is non-reversible. This means that even if the relative humidity temporarily falls below the humidity level, the maximum humidity reading remains unchanged.

Fugenex sensors have a robust design that assures high reliability. The indicators are easy to read and understand, as the length of the reading is proportional to the time that exposure to humidity has exceeded the predetermined level.
