In today’s scientific, industrial, and pharmaceutical environments, accuracy is everything. Even the smallest deviation in measurement can affect research findings, production quality, or compliance with global standards. To achieve such accuracy, laboratories and calibration institutes rely on high-precision reference weights. Among these, the Precision Weights Set 1 mg to 200 g by Masseprazise has established itself as a trusted solution, offering unmatched reliability and performance.

This comprehensive set of 1 mg to 200 g Analytical Weights is designed for professionals who cannot compromise on precision. Manufactured as per the highest metrological standards, these weights serve as primary reference standards for calibrating balances and lower-class weights.

E1 Class Analytical Weights – The Standard of Accuracy

The E1 Class Analytical Weights Box (1 mg to 200 g) from Masseprazise is manufactured in compliance with OIML R111-1:2004 guidelines. E1 is the highest tolerance class in the OIML system, ensuring that these weights are accurate enough to serve as primary reference standards.

They are specifically designed for:

• Calibrating high-precision analytical balances with readability as fine as 0.1 mg to 0.001 mg.

• Serving as reference standards for calibrating lower-class weights (E2 and below).

• Laboratories where traceable calibration is essential to meet international compliance.

Because of their stringent accuracy, these weights are widely used in research labs, calibration institutes, and industries where micro-level precision is critical.

Design and Construction of Monobloc E1 Weights

One of the unique features of this Precision Weights Set (1 mg to 200 g) is its monobloc construction. Unlike conventional weights that may have adjustments, Monobloc E1 Weights are single-piece integral weights with no method of adjustment. This design ensures long-term stability and eliminates the risk of measurement drift over time.

Product Specifications

• Design: Knob type, integral/single-piece (monobloc) wire/bar construction.

• Material: High-grade non-magnetic Austenitic stainless steel (SS-316), chosen for its corrosion resistance and stability.

• Density: 8000 (± 30) kg/m³, ensuring dimensional consistency and long-lasting performance.

• Magnetic Susceptibility (X): < 0.02 – guarantees immunity from external magnetic interference, which is crucial in analytical measurements.

• Nominal Range: 1 mg to 200 g, covering a complete calibration set.

• Number of Weights: 23 units in total, including nominal values of 1, 2, 2, 5, 10, 20, 20, 50, 100, 200, 200, and 500 mg/g.

• Tolerance Class: OIML E1/E2, the highest classes for accuracy.

• Packing: Delivered in a hard case aluminum box that ensures safe storage and protection during transport.

• Calibration Certificate: Supplied with both a standard manufacturing certificate and an ISO 17025:2017 accredited calibration certificate, ensuring complete traceability and compliance with global standards.

Benefits of Masseprazise Monobloc E1 Weights

When investing in calibration weights, laboratories and industries must consider accuracy, stability, and certification. The Masseprazise Precision Weights Set (1 mg to 200 g) delivers on all three fronts:

1. Uncompromising Accuracy

• As E1 class weights, they meet the highest accuracy tolerance levels under OIML standards.

2. Long-Term Stability

• The monobloc construction ensures no risk of mechanical adjustments or degradation over time.

3. Non-Magnetic Properties

• Constructed from SS-316 stainless steel, these weights remain unaffected by external magnetic fields, preventing interference in sensitive measurements.

4. Durable Protection

• Packaged in a robust aluminum box, the weights are protected against dust, corrosion, and handling damage.

5. Certified Calibration

• Supplied with both a manufacturing certificate and an ISO 17025:2017 calibration certificate, ensuring international acceptance and compliance.

Why Masseprazise Precision Weights Stand Out

At Masseprazise, precision is not just a standard—it’s a promise. The Precision Weights Set 1 mg to 200 g reflects the brand’s commitment to providing calibration solutions that combine scientific excellence, durability, and global compliance. By choosing Masseprazise Monobloc E1 Weights, laboratories and industries can be confident in achieving the highest accuracy in every calibration process.

Conclusion

In an era where measurement errors can lead to costly consequences, investing in a reliable set of calibration weights is essential. The Masseprazise Precision Weights Set (1 mg to 200 g), with its E1 class monobloc design, SS-316 stainless steel construction, and ISO-accredited certification, offers a complete solution for laboratories, calibration institutes, and industries that demand nothing but the best.
