Multi-Function Analytical Balance (0.1 mg) - ToronAB™ MF Series
ToronAB™ MF Series multi-function analytical balance combines a fourth-generation ultra-thin electromagnetic force restoration sensor with twelve user-configurable functional settings, delivering 0.1 mg readability across a compact platform suited to a wide variety of working environments. Four capacity models span between 100 g and 220 g, each available in both external and auto-internal calibration variants. At 6 kg and 305 × 210 × 305 mm, the MF Series targets space-constrained workstations and portable-adjacent applications where a standard-format analytical balance is impractical.
Standard models with external calibration use a separately supplied calibration weight placed on the pan by the operator, making them cost-effective for environments where calibration is infrequent. Auto-internal calibration models deploy a built-in reference weight automatically when the balance detects temperature drift, removing the need for manual calibration steps during continuous operation. The auto-internal calibration variant also supports one-click manual calibration for on-demand correction when conditions shift. Both calibration types share the same functional settings, display, and RS232 connectivity.
The three-sided glass draft shield uses a glass extension track on each door to prevent unintended sliding, and the door-slot design simplifies sample loading with large containers. A standard φ80 mm 304 stainless steel pan accommodates most laboratory vessels, with a φ90 mm pan available as an option. Adjustable leveling feet and a built-in level bubble confirm correct horizontal positioning before use. The wide-angle HD LCD display with a 96 × 24 mm screen presents the readout clearly at various viewing distances.

Multi-Function Analytical Balance (0.1 mg) - ToronAB™ MF Series Key Features
The ToronAB™ MF Series packs twelve functional settings into a compact platform, offering the same analytical capability as larger instruments in a reduced footprint.
- Fourth-Generation Ultra-Thin EMFR Sensor: advanced compact force cell delivers 0.1 mg resolution while keeping the overall balance depth to 305 mm, suited for bench space-constrained laboratory environments
- Wide-Angle HD LCD Display: the 96 × 24 mm screen presents mass readings clearly across a wide horizontal viewing angle, reducing readout errors in shared laboratory settings
- Auto Timed Internal Calibration (N Models): balance monitors ambient temperature and deploys its built-in calibration weight automatically when drift is detected, maintaining accuracy without operator intervention
- One-Click Manual Calibration (N Models): a single keypress initiates on-demand calibration of the internal reference weight, allowing immediate recalibration when working conditions change
- External Calibration (Standard Models): standard models perform calibration using a separately supplied calibration weight placed on the pan, guided by a simple key sequence
- Estimation Digit Display (Optional): an additional estimated digit extends the displayed reading, helping operators monitor convergence and stability during sample settling
- Tare Function: full-capacity tare zeroes the display with any container across the entire weighing range
- Counting Function: piece-count mode calculates quantity from a stored reference piece weight, supporting production counting and component verification tasks
- Percentage Weighing: compares each reading against a stored reference to display a percentage value, supporting formula verification and fill ratio control
- Peak Hold: locks the displayed maximum reading during dynamic weighing events, capturing peak mass for filling, dispensing, and process monitoring
- Unit Conversion: reading switches between g, mg, ct, and oz without hardware adjustment, supporting multi-discipline use across a single instrument
- Multi-Mode Print Output: three output modes (continuous real-time, continuous stable, and single-point) align balance output with the operator's workflow
- RS232 Serial Interface: standard RS232 connects the balance to printers, PCs, or central control equipment; baud rate is user-configurable at 1200, 2400, 4800, or 9600 bps
- Display Speed and Sensitivity Adjustment: response characteristics are adjustable between fast readout and stable display to match the sample type being weighed
- Overload and Fault Alarm: visual alerts for tare overload, weighing underload, and general faults protect the sensor and prevent undetected measurement errors
- 304 Stainless Steel Weighing Pan: standard φ80 mm pan provides a corrosion-resistant, chemically inert weighing surface; a φ90 mm pan is available as an option
- Glass Extension Track: each draft shield door rides on a dedicated extension track, preventing unintended sliding and maintaining a sealed weighing environment during operation
- Three-Sided Glass Draft Shield: three-panel sliding door design provides access from multiple angles, simplifying sample placement and container handling
- Adjustable Leveling Feet: four adjustable feet and a built-in level bubble allow the operator to confirm correct horizontal positioning on any bench surface
Theory and Method
The ToronAB™ MF Series uses a fourth-generation ultra-thin electromagnetic force restoration (EMFR) cell to convert applied mass to a digital reading. A flat coil assembly suspended in a permanent magnetic field connects directly to the weighing pan through a rigid linkage. Sample mass deflects the coil from its equilibrium position, and the control electronics restore it by supplying a precisely measured restoring current. The current magnitude is linear with applied force, and the microprocessor translates it to a mass reading at 0.1 mg resolution.
Calibration aligns the balance output with a traceable mass reference, correcting for offsets introduced by temperature or environmental drift. External calibration models require the operator to place a known calibration weight on the pan and initiate the sequence; the balance stores the resulting correction factor for subsequent readings. Auto-internal calibration models monitor ambient temperature and deploy an integrated reference weight automatically when drift exceeds the correction threshold. A one-click trigger also allows on-demand calibration of the auto-internal variant without removing it from service.
The three-sided draft shield uses a glass extension track on each door, preventing panels from sliding open during operation or transport. The 304 stainless steel pan provides a chemically inert, easy-clean weighing surface resistant to typical laboratory reagents. Adjustable leveling feet compensate for uneven bench surfaces, and the built-in level bubble provides a visual reference for horizontal orientation before each weighing session. The ultra-thin fourth-generation EMFR cell reduces the overall platform depth to 305 mm, lowering the bench footprint without affecting measurement accuracy.
