Selection guide for stainless steel set weights for balance calibration

Choosing a suitable set of stainless steel set weights requires consideration of multiple factors, including usage, precision level, specification combination, and brand budget. Below, Shanghai Tingheng will provide a detailed guide for choosing weights.

1、 Clearly define the main purpose

This is a step in selecting the weight core, as it directly determines the level of accuracy you need.

1Teaching demonstration/School laboratory:

·Accuracy requirement: Not high, mainly used to qualitatively demonstrate quality concepts.

·Recommended level:M2level orM3level It can meet the demand.

·Features: High cost-effectiveness, sufficient to cope with the wear and tear in student experiments.

2Business/Industrial weighing (such as vegetable markets, factories):

·Accuracy requirements: Used for calibrating platform scales, cutting scales, etc., requiring a certain level of accuracy.

·Recommended level:M1level It is a common choice. If used for high-precision electronic scales, it may be necessary toF2Grade.

·Attention: Commercial weights usually require mandatory calibration, and when purchasing, you should choose weights with calibration certificates.

3Precision laboratory/scientific research/Quality inspection:

·Accuracy requirement: Very high, used for calibrating high-precision analytical balances.

·Recommended level:F1level orF2Grade. For higher-level metrology and scientific research, it may even be usedE2level orE1Grade.

·Requirement: Equip calibration certificates to prove the accurate quality value of each weight.

·Family/Hobbies (such as baking, fishing):

·Accuracy requirement: very low.

·Recommended level: No level orM3level Ordinary stainless steel or electroplated weights are sufficient, and the price is cheap.

2、 Understand the accuracy level

The grade of weights represents their allowable range of error. The higher the level, the smaller the error and the more expensive the price. According to international standardsOIML R111Suggestion: The approximate level from low to high is:

M1→M2→M3→F1→F2→E1→E2

·MGrade: Industrial grade, with a relatively large allowable error.

·FGrade: Fine level, used in laboratories.

·EGrade: High precision grade, used for calibration in metrology institutes and higher levels.

Simple Choice:

·Daily use: SelectM1

·General experiment: SelectF2

·Precision analysis: selectionF1Or higher
