Semi-Micro Analytical Balance 0.01mg 82/210g ATOMFAIR®

This semi-micro analytical balance requires controlled environmental conditions and mandatory preheating to achieve specified metrological performance. Operational constraints include temperature stability, humidity limits, and external calibration procedures.

• Environmental stability requirement: Operate within 18°C to 23°C and 20% to 80% relative humidity to maintain accuracy and repeatability.
• Preheating threshold: Allow 30 to 60 minutes of warm-up time after power-on before performing any zeroing, calibration, or sample measurement.
• Automatic recalibration trigger: Recalibration is automatically initiated when ambient temperature changes exceed 1.5°C or when two hours have elapsed since the last calibration.
• Stabilization response time: Allow a stabilization period of up to 2.5 seconds after sample placement before recording the mass reading.
• External calibration protocol: Use a 10-gram external calibration weight to correct for environmental drift and maintain linearity.

Proper initialization and calibration procedures are critical for accurate mass determination. Follow these steps to prepare the balance for measurement.

Required Equipment: External calibration weight (10 g)

1. Power-on and warm-up
   Connect the balance to the power supply and allow it to warm up for at least 30 minutes before use.
2. Verify environmental conditions
   Confirm that the ambient temperature is between 18°C and 23°C and relative humidity is between 20% and 80%.
3. Perform zero adjustment
   Ensure the weighing pan is empty, close the draft shield, and press the tare or zero button to reset the display.
4. Execute external calibration
   Place the 10-gram calibration weight on the pan, close the draft shield, and initiate the external calibration routine.
5. Load sample and record measurement
   Place the sample on the pan, close the draft shield, wait for the stabilization indicator, and record the displayed mass.

The EB82G-01MG-R-03 semi-micro analytical balance delivers 0.01 mg readability with dual-range capacity (82 g / 210 g) and ≤2.5 s stabilization, but requires a 30–60 minute warm-up and strict environmental control (18–23°C, 20–80% RH) to maintain ±0.02 mg repeatability and linearity.

Positive

• Dual-range capacity with 0.01 mg readability: Provides 82 g and 210 g maximum capacity thresholds at 0.01 mg readability, enabling trace mass determination across a wide sample mass range without switching instruments.
• Fast stabilization under 2.5 seconds: Average stabilization response time ≤2.5 seconds reduces measurement cycle time, improving throughput in high-volume analytical workflows.

Trade-offs

• Mandatory 30–60 minute warm-up period: Requires 30–60 minutes of power-on initialization before calibration or specimen loading to preserve semi-micro resolution linearity, delaying immediate use.
• Narrow operating temperature and humidity range: Operates reliably only within 18–23°C and 20–80% RH; deviations may degrade repeatability and linearity, necessitating climate-controlled laboratory infrastructure.
