Reliable Calibration Weights for Laboratories
Engineered to meet the highest standards, these calibration weights are suited for demanding applications in calibration and testing laboratories. Accurate marking, adherence to OIML regulations, and a polished stainless steel build ensure consistent, repeatable results for precision weighing instruments. The provided calibration certificate guarantees traceability for critical laboratory procedures.
Premium Protective Design
Designed with both durability and safety in mind, the weights are supplied in a cushioned wooden box. The protective interior, along with the polished finish and corrosion-resistant properties, maximizes longevity and keeps the weights in pristine condition. Supplied forceps and gloves make handling smaller weights safe and contamination-free.
Versatile Use and Compliance
These certified weights support a wide range of uses-from calibration of analytical balances to educational demonstrations and quality assurance in pharmaceutical and commercial sectors. The engraved values and OIML compliance ensure easy identification and universal acceptance across global laboratories and standards-driven industries in India.
FAQ's of Weight box:
Q: How should the cushioned wooden weight box be used in laboratory settings?
A: To use the weight box in a laboratory, open the cushioned wooden case carefully and select the required weights using the supplied forceps and gloves, especially for milligram-sized weights. Handle each weight by its designated accessory to prevent contamination or surface damage, then place it on the analytical balance for calibration or testing purposes.
Q: What are the main benefits of the mirror-polished, stainless steel weights supplied in this set?
A: The weights feature a mirror-polished, corrosion-resistant finish that ensures durability and easy cleaning. The engraved values and robust cylindrical and leaf shapes allow for precise calibration and minimize the risk of mix-ups or errors during measurements, enhancing accuracy in laboratory or educational applications.
Q: When is it necessary to calibrate analytical balances using certified weights like these?
A: Calibration should be performed regularly or whenever balances are moved, serviced, or show irregular results. Using certified weights with supplied calibration certificates ensures that the analytical balance delivers accurate and traceable measurements, which is crucial for quality control, especially in pharmaceutical or research laboratories.
Q: Where can these weight boxes be effectively used?
A: These weight boxes are ideal for use in calibration and testing laboratories, educational institutions, pharmaceutical quality control departments, and commercial or retail settings that require precise weight verification. Their compliance with OIML standards makes them suitable for both national and international use.
Q: What processes are followed to ensure the compliance and accuracy of these weights?
A: Each weight undergoes precision machining and is calibrated against OIML standards specific to its class (E1, F1, or M1). Values are deeply engraved to prevent fading, and a calibration certificate is supplied with the set, verifying its accuracy and traceability for professional calibration processes.
Q: How does the cushioned wooden box contribute to the protection and handling of the weights?
A: The cushioned wooden box prevents physical shocks, moisture, and contaminants from affecting the weights. Individual slots and soft lining ensure that each weight remains secure, reducing the risk of scratches or distortion, and maintaining their calibration integrity over time.
