The accuracy of measurements is essential to enhancing practicality in laboratory settings. Analytical balances are laboratory instruments tailored to accurately measure the mass of objects. With a precision down to 0.00001 grams (0.01 mg), these instruments can help to get the most accurate result for scientific experiments. Due to their exceptional sensitivity, itās essential to regularly calibrate the instruments. Unitest Instruments helps with analytical balance calibration in Singapore.
Letās learn about the importance of calibration.
- Variety of Calibration Options: Modern electronic scales offer users the flexibility to choose from various calibration weights based on the scale’s capacity. For example, a 100-gram capacity scale may provide options for either a 100g or a 50g calibration weight, while an s such as a 50-gram, 100-capacity scale might offer choices such as 50g, 100g, or 200g. Using a calibration weight equal to the full capacity of the scale results in the most accurate calibration.
- Internal Calibration Mechanisms: Some scales feature internal calibration weights and use algorithms within their software to calibrate themselves. This process often involves detecting changes in temperature and monitoring the passage of time. These internal weights meet stringent tolerance standards and contribute to the scale’s high accuracy.
- Maintenance and Periodic Checks: While these self-calibrating scales provide ongoing accuracy, it’s advisable to periodically check their calibration to ensure proper functioning. Opting for calibration and testing services in Singapore can help you detect any potential issues and ensure consistent accuracy over time.
- Handling and Storage of Calibration Weights: Proper handling and storage of calibration weights are essential for maintaining their accuracy. Using lint-free gloves prevents fingerprint contamination while storing weights in dust-free containers minimises external influences. Static electricity can attract particles, so suitable storage conditions are crucial.
- Documentation: It’s important to keep documentation verifying the traceability of calibration weights to certified standards. This paperwork is often stored alongside the weights themselves for easy reference and compliance purposes.
- Frequency of Calibration: If you want to make sure to get accurate results every time, you should focus on calibrating the scale more frequently than strictly. This proactive approach helps prevent potential loss of time and effort due to distorted readings from an out-of-calibration scale.
- Timing of Calibration: If youāre planning to calibrate an analytical balance without professional assistance, make sure to perform it when the scale is in a stable state, having been powered on for an adequate duration and left undisturbed in a stable environment. This ensures the most reliable and consistent results.
