Digital Onboard Scales

Right Weigh’s E-Z Weigh digital onboard load scale provides accurate and reliable axle weight measurement of most air-ride tractors or trailers displayed in real weight (kg). Utilizing Right Weigh’s unique design, these exterior gauges allow for a quick and intuitive 2-point calibration, providing accuracy within at least 113 kg or better, with weights showing on an easy-to-read LCD display. This digital line can accommodate most tractor and trailer axle configurations and is intended to withstand typical exterior mounting conditions. An optional mounting kit is available that includes Right Weigh's custom protective box, mounting bracket, and hardware. As with all Right Weigh products, this scale is backed by a 3-year parts warranty. (One unit is required for each axle group being monitored).

Dash Mounted Scales

Right Weight’s dash mounted models read in actual on-the-ground weight (kg, not psi) and calibrate for an accuracy within 200kg or better. These dash scales are designed to monitor single or tandem axle groups with an air suspension that is managed by one height control valve - commonly a tractor’s tandem drives. If a tractor and trailer is a dedicated set, then a second interior load scale can be used to determine the weight of the trailer tandems using a quick disconnect between the tractor and trailer.

Typical damage to “competitor” units

Failed

Gauge is completely unreadable due to no outer protection - this is how most gauges are supplied as standard. Operator can now only guess his limits. Operator needs to remember to shut off air valve manually to prevent gauge from exploding. Weight shown in PSI so operator will still need to convert to kg.

Failed

Operator did not shut off air when driving causing this gauge to blow up. Air supply valve is still in the down position.

Failed

Unreadable gauge due to lack of protection from aftermarket enclosure. Wire used to hold gauge in place. Operator needs to remember to shut off air valve.

Weight shown in PSI so operator will need to convert to kg.
