Gamma Probes |
| |
Small variations in, or low values of large volume magnetic fields, such as that of the earth or fringe fields, around large solenoids, can be measured with these ultra high sensitivity probes. Resolutions of several gammas (10-5 G) to tens of gammas are available depending on the mating gaussmeter. |
|
Application is optimum when fields are homogeneous over lengths grater than 1 ft. The active sensing length of the gamma probe is approximately 3.125 in. |
| |
When ordering a gamma probe, a Model 4065 zero gauss chamber is needed. The standard Model 4060 zero gauss chamber is too small for the gamma probe |
