PREMIUM Series 321 LX Balances

With the 321 series, Precisa is in today’s mindset: offering active, modern thinking professionals the enjoyment of using well designed even trendy products in their working environment. In combination with the excellent quality and easy-to-use interface it takes the new Precisa experience in weighing to the next level.

Going beyond high performance and precision – Series 321 meets today’s and tomorrow’s user expectations regarding design, functionality and reliability of a modern weighing instrument. Swiss quality, a breathtaking look combined with latest technology make Series 321 the first choice for both laboratories and industrial weighing applications where ease-of-use, efficient measurements and reliable results are required.

The sophisticated user-interface utilizes a new softTOUCH technology for its control. Touch pads, illuminated only when a function is active, guide the user and allow fast and error-free operation. The super-bright blueLINE VFD display takes easy reading to a new level.

321 features easyCLEAN – the easy wipe-off balance and draft shield design. The unique concept of the new draft shield with 270° unobstructed view allows tool-free dismantling and assembling in seconds and can be easily cleaned in your dishwasher.

The balance comes as standard with RS232 and USB interfaces and connects to the wide variety of Precisa accessories and communication adapters.
