  • Customer Reviews on Explorer EX423/E Precision Scale from Ohaus

    I used to get my balances from amazon because it's cheaper there, although the ones I see break easily. So I finally ordered an Ohaus one and it's definitely worth the additional cost. I weighed several items repeatedly to test repeatability and the accuracy is excellent. The structure seems very stable and sturdy so I'm expecting to get a good number of years from this.

    The unit was shipped and delivered quickly. The pan size is enough to fit a standard beaker and accuracy is outstanding even when using different units of measurement. Ohaus is right up there with Mettler Toledo.
