Detailed Product Description

Cast Iron Class M Calibration Weight

A Cast Iron Class M Calibration Weight is a moderately accurate mass standard made from cost-effective cast iron, protected by paint/lacquer

against rust. It features handling aids (knob/recess) and clear markings, including its Class M designation and nominal value. Its key strengths

are economy, especially for larger masses, and suitability for calibrating commercial and industrial scales. Its limitations include susceptibility to

corrosion (if coating damaged), magnetic properties, brittleness, and lower accuracy compared to stainless steel weights in Classes F or E.


Key Features:

1.Durability & Strength

2.Precision Calibration

3.Wide Range of Sizes

4.Easy to Handle

5.Corrosion Resistance

6.Accurate Measurement


Compliance:

These weights comply with global regulatory standards, providing users with confidence that their calibration processes meet

the necessary legal and industrial requirements.

Maintenance and Care: Regular cleaning and maintenance of test weights are crucial to maintaining their accuracy. These weights

are typically designed to be easily cleaned, with some models having smooth surfaces that minimize the accumulation of dirt and debris.


Applications:

1.Industrial scales and weighbridges

2.Laboratory balances and scales

3.Calibration of commercial and retail weighing equipment

4.Agricultural and shipping industries

5.Pharmaceutical and food production quality control


Conclusion:

Iron cast standard test weights are a reliable and cost-effective choice for businesses and industries that require precise, heavy-duty                                                   

weighing solutions. Their durability, accuracy, and adaptability make them an indispensable tool for any operation that depends on

consistent, accurate measurements.
