Portable Microwave Moisture Meter MK30R - Deep Moisture

Main Specifications

• a new special instrument for thick materials, penetrates to 30 mm in most materials but can measure running paper webs too down to about 30 g/m2
• suitable materials pulp, paper, corrugated, textiles, wood etc. all materials able to contain water
• applications in laboratory, field and on-line troubleshooting in slow webs
• light weight 1,9 kg, structure IP 65

Extremely wide moisture range up to 8 000 g/m2 water: Can measure practically all processes in the pulp and paper industry and most other fibre productions.

• three high-contrast displays and a diaphragm keyboard
• operating period of 8 hours without battery recharging.
• measuring distance 0 (requires contact), area approximately 40 mm in diameter
• shows a trend curve of recent history, continuously, 64 points on display
• left display's background colour may indicate crossing of preset moisture levels (high/low selected by user)
• when Autotimer is sampling, the center display changes colour
• Autotimer is turned on with the "+" key or with a separate button on the front panel or by an external software command
• switch with a key to a big numeric display
• the recipe system for quickly switching to another regular measuring position. A label and a specific calibration table is associated with each recipe. Changing with a single key press. The table and label are shown in data files and tags.
• can measure both running and static reels. With static reels' profile measurements, the integral distance sensor is used for accurate synchronizing of profile points.
• travel meter is available for getting profiles from static reels. This will synchronize the profiles every time.

• very low noise level in signal, even at very high moisture levels
• superior long-term stability, based on Visilab's extremely stable technology
• simple to use but has a great number of features

• Marker key for adding a peak to moisture value while measuring and saving a data series to a profile. This can be used for marking the start/end of some interesting period
• Flash calibration for generating new calibrations in field conditions. Only the basis weight of material required to get a working calibration. Fine tuning can be done to it after that and it is ready for measuring in a few seconds

• regular calibrations in units of moisture percent (%) but depending on the case, any other unit is possible. The unit can be modified, while using the meter, to become dryweight-% or dryness-%. In some glue weight measurements the glue mass can be more feasible in units of g/m2

• contains a calibration for measuring paper web moisture getting g/m2 in quality with a BW from about 30 g/m2 to 400 g/m2 and a wide moisture range. This is a great feature for measuring paper webs with unexpected BW. Just start measuring! This feature is a standard in every MK30R.

• zeroing of the moisture reading if the difference only is of importance, referring to a sample

    • a tailored version with IP67 class protection is possible at request

    •  tailored special cavities are possible at request

• has useful data capture features, a large data memory of 820 profiles or time series
• free intelligent software AK30, ATOM and AK30Mini with graphics, calibration tables, statistics, data retrieval.
• A laptop can continuously acquire readings from the MK30R while measuring. It can also be configured simply to automatically download all new moisture profiles from the meter when available. Then the user does not need to do anything about it after stopping the measurement session but study the data and report of the findings.
• interfaces available:
    • keyboard and display
    • Bluetooth serial port for PC via either USB or the Laptop's own Bluetooth. The Bt-USB dongle belongs to delivery and is capable of maintaining a link to 100 m distances. The Laptop Bt's range is unknown (5 - 10 m?)
    • optionally a USB port switchable with the Bt

• low power mode when not in active use for saving energy
• measuring speed is 3..6 Hz and output is 5 Hz for moisture data
• suitable for pulp, corrugated, paper and board plus many other materials, like textiles, felts
• excellent for off-line quality control, complaint validation etc.

• if dry weight percent is required for measurements, just turn the measuring unit to DRY-% and it will automatically convert the reading, no specific calibration required
• if dryness percent is required for measurements, just turn the measuring unit to YDRYNESS and it will automatically convert the reading, no specific calibration here either

• data displayed on the colour displays and collected to PC with the AK30, ATOM, AK30Mini or the optional Advanced program:   Check updates..
• our price beats the competition every time
• designed and manufactured by Visilab in Finland



The special version MK30 Sample Holder below for QC of filled and hollow ROUND materials. The system adapts to the varying diameters.


Models MK30R-PF for paper form measurements -- New model

Below a special model MK30R-PF for measuring paper forms and other more complicated materials manually. The display unit is the same as with MK30R. Penetration depth 5 mm


Models MK30R-PX for measurements of pulp, paper and felts  -- New model

A special model MK30R-PX for measuring pulp and paper in a running or static production machine. The extremely small sensing head is at the end of a long stick. It is intended for manual use. It is also suitable for measuring felts and very wet pulp. The construction is very light and easily handled. The display unit is the same as with MK30R. Penetration depth 5 mm



Tips for Users:

   • to keep the meter's battery fully charged, please keep it connected to the charger, power turned off, when not using it. In this way you will ensure that the meter is always ready when you will need it. Even if the battery would be fully charged, it is trickle-charged to keep it full; no harm is done.

    • avoid running the meter's battery completely empty. Recharging it would require more time than expected since the Lithium Ion battery needs a refreshing initial charging before actual charge is put into it. Also, do not take as real the charge indicators if the battery has been run empty. Let it charge overnight to be sure.


    • Advanced software license for an extended PC program

      • More information..
      • Maintenance Pack..

The earlier model MK30 Compact is now discontinued since the new MK30R will be superior to it in all possible ways.


Packing List of a Standard Product Shipping:

    • Model MK30R meter with calibrations according to customer samples plus some other useful ones
    • User's guides in a binder
    • Software in a USB memory stick, full documentation in PDF format
   • model -PSMK power supply (classified), with an instrument cable of 1.2 m of length. The supply has an IEC320 connector for wall power having a nationalized end plug, if possible. The default delivery will have the flat standard European plug if the target is unknown.
    • Bluetooth dongle and software for connection to a PC. The operating distance may be up to 100 m in good conditions. Now we are shipping a new RN41-based system which is a snap to install and use.

    • Moisture standard -STDMK for regular checking for long-term stability
    • a carrying case -CARMK at a very economical price. Keeps the meter protected and ready for use.

This relieves the pulp machine personnel from running with a grabber and samples while checking the current moisture level of the running web. Just go to the web with the meter and take the reading. No more waiting for hours to get the reading from the laboratory, it is instant.
