We are proud to offer a wide variety of probe types. The most common is the “Standard Weight” probe. If more weight is needed and a little extra width is acceptable, then the “Asphalt Weight” is the probe of choice. The “Extra Weight” Probe is the same diameter as the “Standard Weight” but a little longer and heavier. We also make probes specifically for railcar and other specialties. Although the vast majority of our customers are able to utilize one of these, you may need something a little different. Inform your representative of your needs, and we will work to customize a probe using various combinations.
