Secure Area



The BSQ bench scale base range offers an unrivalled combination of accuracy and strength. The high quality Avery Weigh-Tronix Quartzell™ weight transducer allows users to weigh any item, from a miniature component to an 80 kg box, while the design offers exceptional protection against tough environments.

  • New Quartzell base technology
  • 1 billion internal counts
  • Up to 3.5 million usable resolution
  • 100,000 divisions non verifiable accuracy
  • Repeatability +/- 0.01g

Unrivalled Accuracy

The BSQ is a highly accurate digital bench base with over 1 billion internal counts and a readability of over 3.5 million divisions (unapproved). In practice, this means that the BSQ can detect even the tiniest of weight changes with astounding precision.

Featuring the very latest state of the art suspended Quartzell technology, the BSQ guarantees repeatable balance accuracy at all times. Small and large items can be weighed on a single base, allowing one scale to do a job that might previously have required several. With a fast return to zero between readings, the BSQ provides the speed and repetitive accuracy that can be vital in situations where highly accurate weight readings are required.



The clamshell cover is fully enclosed, reducing the likelihood of environmental interference caused by the accumulation of dust and dirt or even drafts which might otherwise cause slight nuances in weighing accuracy. An optional draft cover is available for the low capacity 1kg and 5kg BSQ bases, to help combat the effect of small air movements on the scale’s accuracy and performance.


Fluids and Dirt

Built-in drip pathways help to channel unwanted dirtand fluids away from critical areas within the base. This clever design makes the scale suitable for use in dirty, oily environments where liquids such as cutting fluids could otherwise affect the accuracy of the Quartzell weighing element.


Thermal Resistance

The internal design of the higher capacity 35kg to 80kg scale offers an excellent thermal coupling barrier, enabling weighing of hot items while protecting against a thermal shift that could affect the accuracy of the base.

Strength by Design

BSQ bench scale bases are exceptionally rugged by design. These tough and resilient bases are engineered to resist over-loading and sudden dropped loads, with up to 1100% overload protection as standard.

The rugged die-cast clamshell case and anti-shock spring suspension system protects the Quartzell weight sensor from sudden impacts and overloads. This design and construction technique allows the scale to withstand overloads of more than ten times its capacity, without affecting accuracy. Designed for use in tough industrial environments, the BSQ is versatile enough for use in laboratories and other applications that require precision weighing.



Link the BSQ with a weight indicator or computer to capture and display weight data. Peripherals link with the scale via RS232 or USB ports. The base can be powered via either of these ports, giving additional flexibility when weighing remotely.
