Optima OP-928 Portable Weigh Pads Axle Scale Truck Scale
The Optima OP-928 is designed for quick two-wheel weighing and comes as a complete kit ready to use out of the box. It emphasizes portability and straightforward setup, making it suitable for fleets that need on-site checks without a full scale. The system is described as easy to use and capable of weighing two wheels at a time, which supports rapid weight verification for loaded trucks and trailers.
310 Series Exterior Analog Axle Load Scale
This Right Weigh model provides an on-the-ground tandem axle group weight displayed in pounds on a 3 ½” gauge. It emphasizes a simple installation and calibration process and operates in a broad temperature range from -40°F to 140°F, making it suitable for varying regional climates. The analog readout offers a straightforward, low-power method to read axle weights quickly on rugged ground surfaces.
BIT Air Scale 18-Wheeler Set
The Blue Ink Tech BIT Air Scale kit delivers real-time monitoring via a mobile app. It provides total truck weight, cargo load, and axle-weight data directly on a smartphone, offering flexible on-the-road access. The kit includes T-fittings compatible with air suspension lines, plus necessary mounting hardware and an installation manual. It suits operators needing remote visibility and digital data capture for fleet management.
Right Weigh 510-46-RK Tandem Axle Load Scale Kit
This exterior kit displays the tandem axle group weight in pounds on a clear readout. It is designed for straightforward installation and calibration, with an air line installation kit included to connect to your suspension system. The setup emphasizes a reliable, vehicle-ground readout ideal for quick checks on road or yard.
Right Weigh 201-EBT-01B Exterior Digital Axle Load Scale
This exterior digital scale is housed in a weather-resistant enclosure with bracket and stainless mounting hardware. It displays the on-the-ground axle group weight in pounds on a digital readout and uses a single air pressure sensor to monitor either one drive axle or a trailer axle group with one height control valve. It provides a robust, durable option for exposed mounting environments.
Right Weigh 310-54-RK Onboard Scale Kit
The 310-54-RK is an onboard tandem axle scale that displays the axle group weight on a readable 3 ½” gauge. It comes with 30 feet of air line and fittings to connect to an air bag on the suspension, plus a straightforward installation and calibration process. This kit supports integrated weight monitoring for vehicles with air suspensions.
Buying Guide: Key Purchase Considerations
When selecting portable axle scales, consider compatibility with your suspension type. Analog gauges offer simplicity and low power use, while digital and Bluetooth-enabled systems provide real-time data and remote access, valuable for fleets tracking loads across multiple vehicles. Readout visibility, gauge size, and enclosure durability matter for yard or roadside use. Installation effort matters; some kits include air lines and fittings, others require more extensive mounting. Temperature tolerance is important for varying climates, particularly in regions with extreme cold or heat. Finally, evaluate whether you need onboard (in-vehicle) or exterior (ground-mounted) solutions based on your maintenance routines and space constraints.
Another key factor is data integration. Bluetooth or app-based systems can connect with fleet management software, enabling better load planning and compliance checks. If you frequently train drivers or operate in busy environments, choose a model with a straightforward calibration process and clear, legible readouts. For mixed fleets, it helps to have a kit that supports multiple axle configurations and can be adapted to both single and tandem axles.
