PRODUCT OVERVIEW
Product Overview & Core Mechanism
The Fristaden Lab FA224NPRO Analytical Balance Series represents the pinnacle of laboratory precision, engineered with advanced electromagnetic force restitution sensor technology to deliver authentic 0.0001 g (0.1 mg) analytical sensitivity up to a 210 g capacity. Unlike standard load-cell precision scales, the FA224NPRO features an enclosed three-door glass draft shield chamber that isolates the 90 mm stainless steel weighing pan from ambient room drafts and temperature micro-currents. Outfitted with a responsive 5-inch digital LCD touchscreen, the balance includes an official Calibration Certificate standard—making Fristaden Lab the premier choice for research-grade verification without inflated premium markups. Available in both an Auto-Internal Calibration model and a 200g F1-Class External Calibration model.
Target Applications & Industry Use Cases
- Pharmaceutical Compounding & Fine Botanical Formulation: Critical for compounding pharmacists, botanical extractors, and peptide formulators requiring exact 0.1 mg dosing for active pharmaceutical ingredients (APIs), micro-powders, and potent reagents.
- Analytical Chemistry & R&D Laboratories: Ideal for university research, chemical synthesis, volumetric solution standardization, and gravimetric analysis requiring strict repeatability within a ±0.0003 g linearity tolerance.
- Density Determination & Material Testing: Utilizes built-in specialized touchscreen software modes to perform automated liquid and solid density calculations, percentage weighing, and sample moisture loss analysis.
- High-Value Precious Metal Assay & Gemology: Perfect for assay labs, refiners, and master jewelers requiring extreme sub-milligram precision when weighing rare gemstones, gold alloys, and platinum group metals in carats (ct) or grams (g).
- Industrial Quality Control (QC): Enables high-accuracy sample preparation and batch audits with direct RS-232 serial data logging to external PCs or printers for regulatory compliance.
Product Line Comparison
Analytical Balances (FA Series) vs. Precision Balances (HC Series): Strain gauge precision balances (like the HC Series) are designed for heavy capacity open-pan weighing up to 15 kg at 0.01 g readability. The FA Analytical Balance uses an electromagnetic force restoration transducer capable of 0.0001 g (0.1 mg) resolution inside a draft shield—providing 100x higher sensitivity for sub-milligram applications.
Auto-Internal Calibration vs. External Calibration Models: The FA224NPRO Internal Calibration model features an motorized internal calibration weight that automatically standardizes the sensor on demand or following thermal shifts, eliminating the need to handle external masses. The FA224NPRO External Calibration model relies on manual calibration using an included certified 200 g F1-class stainless steel calibration weight.
Frequently Asked Questions & Operations
What is the difference between 0.1 mg Readability and Minimum Weight?
Readability (0.0001 g / 0.1 mg) represents the smallest numerical increment displayed on the touchscreen. However, the minimum effective load for accurate measurement on this analytical balance tier is 50 mg (0.0500 g). Attempting to weigh single samples below 50 mg without a tare base will fall below the electromagnetic sensor's active threshold.
Why does the analytical balance require a 30 to 60-minute warm-up time?
High-precision electromagnetic force sensors and internal circuitry undergo subtle thermal expansion when powered on. Allowing a 30 to 60-minute warm-up period ensures the core components achieve thermal equilibrium, preventing numerical drift and securing repeatable 0.1 mg accuracy. (Pro-tip: Keep the balance continuously plugged in or in sleep mode for instant availability).
How do I perform calibration on the FA224NPRO?
For the Internal model, press the CAL key on the main screen to initiate automated internal motor calibration. For the External model, enter the Setup menu, select Ext-Cal, wait for the screen to flash "200.0000g", place the included 200 g F1 calibration mass on the pan, close the draft doors, and wait for the reading to stabilize.
What touchscreen weighing modes are included?
The 5-inch digital interface supports standard mass weighing, specialized Powder Weighing (filters out micro-vibrations during active scooping), Parts Counting (PCS), Percentage Weighing, and Density Calculation.
What are the power supply specifications for the FA Series?
The balance uses an AC 100-240V adapter supplying DC 5V (2A or 3A output) with a standard 5.5 mm x 2.1 mm center-positive plug tip. Always ensure a stable power outlet or surge protector to avoid mainboard voltage fluctuations.
