iWeigh®
The connected on-board scale
iWeigh fits trucks, trailers and tractor-trailers, including doubles, B-trains and heavy haul, on air ride or spring suspension. Each weight goes to the driver's phone, the truck's CAN bus and the Air-Weigh cloud as the truck loads.
The Industry's Most Advanced On-Board Scale Platform
Take weight data into your own hands! Our iWeigh® CAN bus and Bluetooth®-connected on-board scale platform was developed from the ground up for today’s tech-advanced vehicles. iWeigh® was designed for seamless connection and compatibility with our industry-leading LoadMaxx® series for both tractors and trailers. This new platform brings current LoadMaxx® fleets into the future by enhancing on-board scale functionality. Simply add an iWeigh® scale to a tractor or trailer, and it automatically pairs with the LoadMaxx® scale on the corresponding equipment to add vehicle weight and GVW. Our free app provides the fastest and most secure Bluetooth® connection in real time, allowing drivers to view weights from anywhere inside or outside the vehicle.

“With EVs, the cars are getting heavier. With every electrification point of a vehicle, it’s 200 to 300 more pounds vs. a gas version. A hybrid is 200 to 300 pounds more than the gas car and a full EV is another 200 to 300 pounds. That makes these scales all the more critical.”
Mike VanderPloeg Operations Supervisor
“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.”
