An economical floor friction measuring device is what our survey of industry told us was needed.
We answered that with our SCOF devices years ago and have worked hard to continuously improve those devices to keep current with industry demands. We now have an economical answer for DCOF testing with our 925 meter.
Our ASM 925 DCOF meter is very easy to operate. The unit is powered up (by two 9 volt batteries), a zero calibrate run is made and then once a user selects the number of passes, the unit is pushed down to the surface. The test foot starts moving forward as the unit is pressed down and once the test is complete, the user simply lets up and the test foot returns to the docked position. The test path is approximately 2 inches in length and takes approximately 1.8 seconds to run. The DCOF value is displayed and can be saved to a micro SD card in a full size card adapter. When the data is saved, 100 individual data points are saved and displayed with the graph.
As can be seen on the picture of the bottom, we have a single SBR sensor that travels an approximate 2 inch travel. The four corner plunger style switches operate the start and reset of the test foot along with an error code if the meter is lifted slightly or the meter is not held tight to the surface. There will me a message that the meter was up early and the test is cancelled. There are 2 positive stops on each end of the travel slot so the meter can not be pushed down any harder than is required to run the test. There are 4 rubber bump stops to assist in grip on the surface.
Each side is marked with black lines to assist in knowing where the sensor travel area is.
The ASM 925 meter, with the 8.5" x 6.5" outer dimensions, will test 4 directions on most stairs.
Watch the video above and see how easy it is to run a test.
ASM 925DCOF Accuracy
he meter is very simple to operate and independent from the operator for accurate results.
The meter is set up for a single pass, 4 pass or 6 pass run. A 4 pass is designed for running a test in each of 4 directions with 90 degree rotations for each pass. The meter will prompt the user to rotate each time. A 6 pass run is designed for 3 passes in one direction and the 3 passes in a direction perpendicular to the first direction. The meter will prompt the user for each pass.
To the left are 2 examples of the data that is saved to the SD card when chosen to do so. There is a single pass and a 6 pass run for examples. The 4 pass has the 4 graphs on the first page and the 4 columns of data following as in the 6 pass run.
There is an Excel program (enabling Macros required) included on the SD card for graphing the data.
The 925 ships in a hard-shell roll around carrying case sized to fit airline overhead bins.
The unit includes 2 sensor feet with SBR, instructions, micro SD card, brush to clean sensor feet, 2000 grit sandpaper and 2 vials of SLS, 13ml each.
A verification surface is included.
The unit operates on two 9 volt batteries, included.
The meter weight is 6.2 pounds and shipping weight is 24 pounds.
The meter is 8.5" L x 6.5" W x 5.5" H
The carrying case is designed to hold the 925 with accessories and also the 825A with accessories. If you already own the 825A, there are 2 foam plugs that can be removed to carry both meters in one case. The meters are available as a combination kit to ship together as well.
