Slope Meter SSM
The Steep Slope Meter (SSM) combines the features of the No. 1 and the No. 2NS and works well on bulldozers and similar equipment. They are durable and rugged, can be easily read and have a wide range of applications.
The SSM is used to determine "percent of grade" and is calibrated to read from 0-50%.
The "SSM" is used in applications where a steeper slope reading is required (as compared to the No. 2NS), but the operator or engineer requires a reading in "percent of grade".
