Series 390 Semi-micro and Analytical Balances
The frameless draft shield glass allows a barrier-free view and easy access to the weighing chamber. The draft shield glasses can be dismantled for cleaning within seconds without the need for tools. All glasses, the weighing pan, and other parts can be easily cleaned in a dishwasher.
With four different models, HF, HA, HE, and HM, we cover your weighing needs. With the exception of the entry-level model HM, with a mechanical draft shield, you can upgrade your balance with the applications and features you need in the future. Or simply choose the series 390 model HF to have the balance with everything equipped.
Our new unique balance series 390 offers the best ergonomics, including an ultimate low-weighing pan access level, the lowest on the market! Weighing processes can now be performed more comfortably, ergonomically, and easily.
