MYA 5Y Microbalances

Category Laboratory Balances
Manufacturer Radwag
Country of manufacture Poland

The ELLIPSIS series determine weight with impressive accuracy, perform a digital audit, respond to your voice commands and send you light messages. A Digital Weighing Auditor Ensures that your balance is ready for use. It enables air buoyancy compensation in real-time. What is more, it informs about the need for a balance inspection or a periodic audit of the balance’s accuracy and sensitivity.

The 10" display means more information in one place. On the new ELLIPSIS terminal, you will see up to 3 screens, widgets, graphs, statuses, notes, handy measurement history. Uncompromising User Verification. The balance will verify the user using a password, RFID card, fingerprint reader, facial recognition mechanism, or any combination of these. Ambient Light – An Innovative Way for the Balance to Communicate With the User. The light color will tell you about status, process results, procedures, or alerts. Hotspot Use the balance on any device connected to it. This can be a smartphone, tablet, or computer. 

ELLIPSIS works with RFID tags* that can be used to tag your products or formulation ingredients in the database. They can also be used to identify a user. Live Note – Note Down Your Conclusions by adding a voice memo to a measurement series or procedure report. If you prefer to write it down, ELLIPSIS allows you to add a text note. Handy Library where a series of recent measurements or a report ready for digital signature, according to 21 CFR Part 11, can be found. Widgets Prepared to display what you need most at any given moment. Instead of manually leveling your scale - level it automatically.

The ReflexLEVEL System saves you time and gives you maximum precision in your measurements. The balance displays whether the value of the weight you want to weigh is below or above the minimum weight threshold with the Smart Min Weight feature. Adjacency, which takes place at two measurement points instead of one, improves measurement precision over the full weighing range for a more accurate measurement.
