People say the nicest things

Craig Laird
Laird Logs LLC
For the many years that we have been using Air-Weigh products, we are completely satisfied with the quality and service we have received!

Dino Guadagni
Western Distributing
Air-Weigh scales help our fleet to realize our weight issues at the dock – not 60 miles out of route, down the road, after the shipper has closed. This ensures that we maintain our on-time delivery to the customer and reduces out-of-route costs to scales. Better to be proactive than reactive!

Cory Pettersen
Dirt Dawgs Trucking Inc.
We use Air-Weigh scales to ensure that we pick up a full load every time. In fact, the first big haul after we installed them paid for the scales! I also like the peace of mind of knowing we won’t get an overweight ticket.
American Made
Air-Weigh is founded and located in Oregon and all of our scales are American Made. We feel that keeping our product manufacturing local allows us to provide our customers with the highest quality on-board scales around.
