ALE-223, ALE-323 & ALE-623 with 1mg Laboratory Balance Scale NTEP


Free Shipping

Intelligent Weighing Technology ALE-223, ALE-323 & ALE-623 precision balance scale with a .001g accuracy (1mg). This model is NTEP Approved (legal for trade) for Class II applications with a .01g accuracy.The ALE features increased stability, reliable measurements, and quick results utilizing tuning fork. The system utilizes a double ended tuning fork which vibrates when force is applied. The frequency of the vibration changes with the amount of force applied. The tuning fork is not affected by the shock associated with shipping or temperature changes. It is extremely stable, giving high repeatability, durability and temperature resistance.
