Turn it on and slide the Field CheckR® into your degausser, run the cycle and view the results. The Field CheckR® has the unique ability to measure the strength of both vertical and horizontal magnetic fields present during the degaussing cycle then provides you with accurate, numerical results. Our annual factory swap program is recommended for upgrades, calibration, battery replacement, and routine preventative maintenance.

With patented, one-of-a kind technology, internal sensors measure magnetic fields on three display faces, and reports numerical results. The Field CheckR® cycle time depends upon each particular degaussers cycle time and can be used continuously. Refer to the convenient key adhered to the top of the Field CheckR® to evaluate the performance of your degausser and ensure it is performing within tolerance ranges.

The Field CheckR® can be used in multiple degausser designs. However, if you have a small chamber deguasser, we recommend our  Compact Field CheckR®. Let us help you identify the best choice for your needs.
