Our custom designed exterior box is made of impact-modified polypropylene with two stainless steel draw latches. The E-Z Weigh digital scale does not require this mounting box under typical exterior conditions, but it is recommended for use in harsh conditions.

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).

E-Z Weigh Digital Scale Calibration

The E-Z Weigh digital scale can be calibrated quickly and easily using both an empty and loaded axle weight from an accurate in-ground scale. Simply enter the empty weight while the vehicle is empty and the loaded weight while the vehicle is load. Once the two calibration points have been entered correctly, the E-Z Weigh digital gauge is ready to use. Detailed instructions are included with the product.
