Up to three information screens can be displayed simultaneously.

Advanced User Authentication

Supports multiple verification methods including:

• Password login

• RFID card

• Fingerprint recognition

• Facial recognition

• Multi-factor authentication

Ambient Light Status System

Integrated ambient lighting communicates balance status, measurement results, and alerts using color indicators.

ReflexLEVEL Automatic Leveling

The ReflexLEVEL system automatically levels the balance, eliminating manual adjustments and improving measurement precision.

Smart Minimum Weight Monitoring

Displays whether the current sample weight is above or below the required minimum weight threshold for accurate measurements.

RFID Integration

RFID tags can be used to identify users, samples, and formulation ingredients stored in the balance database.

Hotspot Connectivity

The balance can create its own Wi-Fi hotspot, allowing smartphones, tablets, or computers to connect directly.

Live Notes

Users can attach voice memos or text notes to measurement procedures or weighing reports.

Handy Library

Provides quick access to:

• Recent measurement series

• Reports ready for digital signature

• Documentation compliant with 21 CFR Part 11

Two-Point Adjustment

Calibration at two measurement points improves accuracy across the entire weighing range.
