Radwag PS.R2 Series Precision Balance (NTEP Legal for Trade)

What Makes the PS.R2 Stand Out

• Self-calibrating — the balance monitors its own temperature and adjusts automatically throughout the day. You never stop to run a manual calibration routine.
• NTEP Certified Class II, Legal for Trade (CoC 14-045A2) — meets federal and state commercial weighing requirements for cannabis dispensaries, pharmacy compounding, and precious metal transactions.
• Large 5.3-inch backlit display with a dedicated text line showing the product name and tare label — easy to read across a busy lab bench or pharmacy counter.
• Dual RS-232 serial ports let you run a printer and a computer at the same time without swapping cables — a practical advantage most balances at this price range don't offer.
• Built-in ALIBI memory stores up to 100,000 dated and time-stamped weighment records. Tamper-evident and audit-ready for regulated environments.
• Under-pan weighing port built into the base — enables density determination and lets you weigh bulky suspended samples without an external stand.
• IP 43 rated housing resists light liquid splashes and dust — more durable than standard lab balances for pharmacy and production environments.
• Draft shield included on all 128mm pan models (PS 210.R2, PS 360.R2, PS 1000.R2) — protects sensitive 1mg readings from air currents.
• Stainless steel pan — easy to clean, chemically resistant, built to hold up in daily production use.
• Universal 100–240V power supply works anywhere in the US and internationally.
• Wi-Fi connectivity available as a factory-installed option — integrates with lab data systems and LIMS without additional hardware.
• Manufactured in Poland by Radwag, a dedicated balance manufacturer with over 40 years of precision instrument production.
• 2-year manufacturer warranty.

Applications

• Pharmacy Compounding — 1mg readability on the 128mm pan models satisfies USP weighing requirements for powder and ingredient measurement. ALIBI memory supports documentation for state pharmacy board compliance.
• Cannabis Dispensaries — NTEP Class II certification meets point-of-sale legal-for-trade requirements in regulated cannabis markets. The tamper-evident audit trail supports traceability.
• Precious Metals and Jewelry — Class II certification covers commercial gold, silver, and gem transactions. All models cover gram ranges commonly used in jewelry retail and wholesale.
• Laboratory Research and QA/QC — 13 built-in weighing modes cover the full range of routine lab tasks from sample preparation to statistical analysis, without needing external software for basic functions.
• Food Formulation and Production — dosing mode with threshold alerts, totalizing for ingredient accumulation, and checkweighing for portion control make this a capable tool in production environments.
• Industrial Parts Counting — count mode determines piece count from a sample mass. The large-pan .M models handle heavier components that smaller balances can't accommodate.

13 Built-In Weighing Modes

• Weighing — standard mass measurement with display hold and tare.
• Dosing — set a target mass and tolerance thresholds; the display guides the operator to the correct amount.
• Parts Counting — establish a piece weight from a sample and count components by mass.
• Percent Weighing — display results as a percentage of a reference mass.
• Totalizing — accumulate running mass for formulation and mixing across multiple additions.
• Peak Hold — captures and holds the maximum reading during a weighing cycle, useful for dynamic loads.
• Checkweighing — set high and low thresholds; balance signals pass or fail for incoming inspection and portioning.
• Statistics — automatically calculates min, max, average, standard deviation, variance, and range across a sample set.
• Animal Weighing — averaging mode stabilizes the reading for moving or restless subjects.
• Under-Pan Weighing — supports a hook-mount load below the balance for irregular or suspended samples.
• Density Determination — calculates material density using the Archimedes principle, in liquid or air.
• GLP Procedures — generates documented weighing records and diagnostic printouts that meet Good Laboratory Practice requirements.
• Autotest — runs an internal self-diagnostic to verify metrological performance and repeatability.

Onboard Data Management

• Product database — store and recall up to 1,000 product profiles including target weights and tolerances.
• Tare database — save up to 100 container tare values for quick recall.
• Weighment history — last 5,000 weighments stored and accessible on the balance.
• User accounts — up to 10 operator profiles with individual settings and access levels.
• ALIBI memory — 100,000-record tamper-evident audit trail for regulatory documentation and traceability.
