Douglas actually encourages technical upgrades of earlier model Mu-Meters. Our designers specifically ensure that current design developments are applicable to earlier machines so that they can be easily upgraded. It is not uncommon for a 20 year old Mu-Meter to be returned for upgrade to the latest standard.
The world’s best selling CFME system with over 1000 units now sold around the world, Mu-Meter has consistently maintained its market and technical leadership since its launch some 50 years ago.
Mu-Meter Mk 6:
• Purpose-designed for testing airport runways, taxiways and highways.
• The Mu-Meter consists of a small three-wheeled trailer incorporating sophisticated electronic measuring and sensing systems operating in conjunction with a supplied touch-screen laptop computer carried in the towing vehicle.
• The unit produces data which is presented to the operator in the vehicle on the laptop screen and which can subsequently be downloaded to an office PC.
• Fully integrated design with a powerful onboard microprocessor based system for years of trouble-free operation.
• Windows®-compatible software is simple to use and stores a wealth of vital measurement data.
• Mu-Meter produces automatic computerised results in a range of prescribed formats (CAA/FAA/ICAO etc) and many languages.
• The Mu-Meter can be operated in both dry and self-wetting modes and will provide accurate day-to-day measurements as part of a runway maintenance plan.
• Does not require a specialist tow vehicle or a dedicated van conversion.
• Results reports are displayed immediately to determine weather related friction changes for operations management.

Water delivery system
A range of water delivery systems are available as options and can be supplied to supplement the Mu-Meter when it is required to classify runways as defined in the appropriate authority classification specification.
Corrosion protection
The components of the Mu-Meter are heavy duty powder coated for corrosion protection against all conditions and de icing materials encountered at modern airports.
Electronic control and processing system
Information sensing, conditioning, processing, recording, storing and visual displays are all actioned by the electronic system. It is contained in discrete items, these being: the load cell, distance sensor encoder and the central control unit mounted on the trailer.
The marshalling enclosure and laptop processor are mounted in the towing vehicle.
Electrical connections between the units are made through conventional electrical interface connectors giving protection from the ingress of moisture to IP68 standards. A stowage socket is fitted to the back face of the trailer towing plate adaptor to accommodate the trailer-to-towing vehicle connector.
Laptop processor
Mobile Computing Platform Intel® Core™ i5-2520M vPro™ processor (2.5GHz, 3MB Intel Smart Cache, Intel 6 series Express chipset QM67)
4 GB DDR3 SDRAM (max. 8GB) • 12.1” WXGA type LCD (TFT) (1280 x 800 pixels) • Touchscreen Gloved Multi Touch Model: resistive Touch screen
Bluetooth® Version 2.1 + EDR Class 2. Information is passed from the central control unit to the laptop processor screen for constant ‘real time’ evaluation during the measuring run.
Runway & Contractor units are fully compliant with:
1. ICAO Annex 14, Volume 1; Attachment A, Section 7, Para 7.1 of the International Civil Aviation Organisation Airport Services Manual Part 2 (Third Edition-July 1999).
2. UK CAA CAP683 Procedures for Runway Friction Classification and Monitoring.
3. FAA Advisory Circular: Measurement, Construction and Maintenance of Skid Resistant Airport Pavement Surfaces.
Highway unit
Installed software specifically designed for measuring highway surface friction.
Contractor unit
Contains switchable Runway & Highway software making this unit ideal for the contractor who needs to take measurements on both surfaces.
Memory Key
A USB Memory Key is supplied as standard for exporting data for archiving or data transfer.
The Memory Key can be inserted into any desktop PC for archiving.
Display Laptop
The touch screen lets you operate the poly silicon LCD even with gloves on. Anti-reflection coating technology reduces reflectivity. The display is the main user interface. From here the user can display Menus, Programs, Run information and friction/ distance graphs. The user can also perform basic analysis of the test runs. A zoom and pan function allows for close inspection of the graph down to a resolution of 200mm of the runway. This can be conducted immediately after the run has been conducted or later back in the office.
