The Multi-Test Gravelometer is designed for testing automotive materials and coatings for resistance to gravel impact.

The Gun Assembly and Target Chamber can be changed to accommodate different test methods and different angles of impact. The Multi-Test Gravelometer can be changed from one configuration to another in less than 3 minutes.

Easy to Use

The Gravelometer's rugged construction makes it easy to shoot hundreds of panels per day. The Flat Specimen Holder is located on the outside of the chamber for quick loading and unloading and high volume throughput.

Flexible Specimen Mounting

Flat test specimens are mounted at either 90o or 45o for different angles of impact. The Flat Specimen Holder is designed to accommodate a range of thickness. A three-dimensional (3D) Specimen Chamber is also available to accommodate larger objects like hubcaps, springs, and bumper sections.

Precise Control

Gravel Feed Rate is adjusted via an electrically controlled vibratory feeder. Air Pressure and Air Velocity are kept constant because the built-in receiver tank stores and delivers air to the nozzle at a constant pressure and velocity to increase precision. The nozzle air pressure is adjusted to change the speed of the media hitting the test specimen. Air Flow variations are reduced by the use of machined Gun components which fit together precisely to eliminate variations in airflow. Test Time is programmable.

Safety

The Multi-Test Gravelometer is equipped with safety cut-off switches that automatically shut down the machine if either the target plate or specimen holder is opened or the target box is removed. The safety relief valve on the air receiver tank automatically keeps the pressure in the tank below a certain level.

Easy Maintenance

All components of the Multi-Test Gravelometer are positioned to allow easy access for inspection, maintenance and calibration. Its compact modular design saves lab space. You no longer need to keep a different type of tester for each and every test that you are required to run.
