Semi-Micro Analytical Balance 51/210g 0.01mg ATOMFAIR®

This balance requires a controlled environment with temperature between 18°C and 23°C and relative humidity between 20% and 80% to maintain measurement accuracy. A mandatory preheating period of 30 to 60 minutes is required after power-on before any zeroing or calibration operations.

• Environmental Operating Range: Operate the balance within an ambient temperature range of 18°C to 23°C and relative humidity between 20% and 80% to maintain specification accuracy.
• Preheating Requirement: Allow the balance to warm up for 30 to 60 minutes after power-on before performing zeroing or calibration to ensure thermal equilibrium.
• Calibration Trigger Conditions: The balance autonomously triggers recalibration when ambient temperature varies by more than 1.5°C or when elapsed time exceeds 2 hours to mitigate environmental drift.
• Power Supply Configuration: Connect the balance to a 220V AC / 50Hz mains supply via the provided 12V DC / 2A adapter; do not use an unregulated power source.
• Draft Shield Usage: Use the glass draft shield and enhanced spatial air shielding to minimize air currents that can affect microgram-level readings.

This procedure describes the initialization and calibration workflow for the ATOMFAIR EB51-210G-01MG-R semi-micro analytical balance. Follow these steps to achieve accurate measurements after power-on.

Required Equipment: ATOMFAIR EB51-210G-01MG-R Semi-Micro Analytical Balance

1. Power On and Warm Up
   Power on the balance and allow the instrument to warm up for 30 to 60 minutes to achieve thermal equilibrium.
2. Perform Zeroing
   Perform zeroing by pressing the tare or zero key with no load on the pan.
3. Load Calibration Weight
   Place the external calibration weight (e.g., 10 g) on the pan and initiate the external calibration routine.
4. Remove Calibration Weight
   Remove the calibration weight and verify that the balance reads zero.
5. Add Sample and Measure
   Add the sample to the pan and wait for the stabilization indicator (approximately 2.5 seconds) before recording the measurement.
6. Perform Micro-Additions
   Use the optimized micro-sampling digital filtering to stabilize readouts against ambient drift when adding minute powder or fluid specimens.

The ATOMFAIR EB51-210G-01MG-R semi-micro analytical balance delivers 0.01 mg readability with a 2.5-second stabilization time, dual 51/210 g capacity, and external calibration, optimized for analytical chemistry powder sampling and multi-range verification workflows.

Positive

• Fast 2.5-Second Stabilization: The balance achieves an average stabilization time of 2.5 seconds, enabling efficient measurement cycles in high-throughput analytical workflows.
• RS232 Communication for LIMS: An integrated bidirectional RS232 interface enables direct data transfer to printers, host computers, and laboratory information management systems.

Trade-offs

• Mandatory 30-60 Minute Preheating: The balance requires a 30 to 60 minute warm-up period after power-on before performing zeroing, calibration, or measurements to ensure linearity and stability.
• Strict Environmental Operating Limits: Operation is restricted to 18-23°C and 20-80% RH, necessitating a controlled laboratory environment to maintain specified accuracy.
