The EB31-120G-01MG-R semi-micro analytical balance requires strict environmental control and mandatory preheating to maintain its 0.01 mg readability and ±0.02 mg repeatability. External calibration with a 10 g standard weight is necessary to comply with metrology specifications, and the balance automatically recalibrates if temperature varies more than 1.5°C or if two hours elapse.
- Environmental Operating Conditions: Maintain ambient temperature between 18°C and 23°C and relative humidity between 20% and 80% RH to ensure stable metrological performance.
- Preheating Requirement: Allow the balance to warm up for 30 to 60 minutes after power-on before zeroing or performing calibration.
- Calibration and Recalibration Protocol: Perform external calibration using a 10 g standard weight, and note that the balance will automatically recalibrate if temperature fluctuates more than 1.5°C or if two hours pass.
- Stability and Drift Management: The balance's electromagnetic force sensor and draft shield are designed to suppress airflow interference and baseline drift, but careful placement away from drafts and vibrations is still required.
- Power Supply Specifications: Connect the balance to a 220V AC / 50Hz mains supply via the provided 12V DC / 2A adapter to ensure proper operation.
Follow these steps to prepare the balance for accurate semi-micro weighing. The procedure ensures proper warm-up, environmental verification, calibration, and sample handling.
Required Equipment: Standard 10 g external calibration weight
- Preheat the balance
Allow the balance to warm up for 30 to 60 minutes after powering on before performing any measurements. - Verify environmental conditions
Confirm that the ambient temperature is between 18°C and 23°C and relative humidity is between 20% and 80% RH. - Perform external calibration
Load the standard 10 g external calibration weight to calibrate the balance according to laboratory metrology specifications. - Zero the balance
Tare the balance after calibration and ensure a stable zero reading before adding samples. - Add trace sample
Use the micro-addition function to add minute powder or fluid specimens while monitoring the stabilized readout.
How does the dual-range design of the EB31-120G-01MG-R balance affect measurement precision across the 31g and 120g capacities?
The balance offers uniform 0.01mg readability across both ranges, with ±0.02mg repeatability and linearity. The 31g range is optimized for ultra-trace measurements, while the 120g range accommodates larger samples without sacrificing precision, making it suitable for trace powder analysis and micro-dosing.
What are the environmental and calibration prerequisites for achieving specified performance with the EB31-120G-01MG-R semi-micro balance?
The balance requires an operating temperature of 18°C–23°C and humidity 20%–80% RH. It uses external weight calibration with a standard 10g mass. A mandatory preheating period of 30–60 minutes after power-on is required before zeroing or calibration to ensure linearity.
How does the split-body detachable display design of the EB31-120G-01MG-R improve measurement reliability in sensitive weighing applications?
The detachable display isolates micro-vibrations from manual operations, preventing operator-induced errors. Combined with the rear-mounted electromagnetic force sensor and panoramic glass draft shield, it suppresses airflow interference and baseline drift, achieving ≤2.5 second stabilization time.
The EB31-120G-01MG-R semi-micro analytical balance provides dual-range 31g/120g capacity with 0.01mg readability and ±0.02mg repeatability, utilizing a rear-mounted electromagnetic force sensor and split-body design for vibration isolation, but requires a 30-60 minute warm-up and strict environmental controls (18-23°C, 20-80% RH) for accurate operation.
Positive
- Dual-range high-precision weighing: Offers 31g and 120g maximum capacities with uniform 0.01mg readability and ±0.02mg repeatability, enabling ultra-trace measurements across two ranges in a single instrument.
- Vibration-isolating split-body design: Detachable display separates manual operation vibrations from the weighing block, while the rear-mounted electromagnetic sensor and air shielding achieve ≤2.5s stabilization and suppress ambient drift.
Trade-offs
- Mandatory warm-up period: Requires 30-60 minutes of preheating after power-on before zeroing or calibration, delaying initial workflow startup.
- Strict environmental requirements: Operates reliably only within 18-23°C and 20-80% RH; deviations may degrade metrological performance and require recalibration.
