Product Code

BM 500



The A&D BM-500 is a micro analytical balance with the capacity of 520 g and readability of 0.1 mg, designed for repeatable and reliable measurements in areas where accuracy is key. The balance includes a built-in ionizer that removes charge from samples prior to measurement, ensuring accurate results and improved stabilization. The balance provides accurate readings and automatically recalibrates based on ambient temperature changes, thanks to its integrated internal calibration. The BM-500 series balance performs automatic calibration when detecting changes in ambient temperature, and users can also utilize the convenient one-touch calibration function whenever needed.

The BM-500 series has a built in fanless ioniser that reduces static on the sample, resulting in more stable measurements when using easily charged containers such as disposable weighing boats or plastic centrifuge containers. It also features a percent mode which allows the user to easily measure the weight of a sample as a percentage of a 100 % reference mass – this can be useful for target weighting, or checking sample variance, easily without having to carry out additional calculations.
