Calibration Weights for Laboratory Balance Verification<\/h1>\n

Calibration Weights<\/strong> are used to check the performance of laboratory balances and other weighing instruments using known reference masses. The operator places a selected weight on the weighing pan and compares the displayed result with the nominal or calibrated mass value.<\/p>\n

Regular intermediate checks help laboratories identify drift, repeatability problems or unexpected measurement deviations before they influence routine test results. Liya Test supplies both individual M1 Class weights and an F1-F2 Class precision weight set.<\/p>\n

M1 Class Individual Weights<\/h2>\n

The M1 product range includes 1 kg, 2 kg, 5 kg, 10 kg and 20 kg<\/strong> individual weights.<\/p>\n

The corresponding product codes are LT-G9070, LT-G9072, LT-G9074, LT-G9076 and LT-G9078<\/strong>. Liya specifies these individual models as cast-iron weights coated with black epoxy-based paint<\/strong>. The protective coating helps reduce direct environmental exposure of the cast-iron body.<\/p>\n

Different nominal values allow the operator to check several points within the operating range of a laboratory balance or industrial scale.<\/p>\n

F1-F2 Stainless Steel Weight Set<\/h2>\n

The LT-G9100 Calibration Weight Set<\/strong> is intended for more precise weighing applications and combines F1-F2 Class stainless steel masses<\/strong>.<\/p>\n

The set includes 1 g, two 2 g, 5 g, 10 g, two 20 g, 50 g, 100 g, two 200 g, 500 g and 1 kg<\/strong> reference masses. This combination allows different test loads to be created without requiring a separate weight for every possible value.<\/p>\n

How Are Calibration Weights Used?<\/h2>\n

Before verification, the user should place the balance on a stable and vibration-free surface. The instrument is then zeroed according to its operating procedure.<\/p>\n

A suitable reference weight is placed carefully at the required position on the weighing pan. The displayed reading is compared with the reference value. Additional measurements can be performed at several points across the balance range.<\/p>\n

Weights should be handled carefully to avoid contamination or mechanical damage. For higher-accuracy classes, suitable gloves, tweezers or handling tools help reduce the transfer of oil, dust and moisture to the weight surface.<\/p>\n

OIML R 111 Accuracy Classes<\/h2>\n

OIML R 111-1<\/strong> defines technical and metrological requirements for reference weights from 1 mg to 5000 kg<\/strong> and includes the classes E1, E2, F1, F2, M1, M1-2, M2, M2-3 and M3<\/strong>. The recommendation covers weights used with weighing instruments and as standards for verification or calibration.<\/p>\n

OIML published an Amendment 2025<\/strong> to R 111-1:2004, so the current reference is the 2004 recommendation together with the 2025 amendment.<\/p>\n

Calibration Certificates<\/h2>\n

Liya states that traceable calibration certificates must be ordered separately when required<\/strong>. This distinction is important: the physical class designation and the existence of a traceable calibration certificate are not the same thing.<\/p>\n

As a result, Calibration Weights<\/strong> provide laboratories with individual M1 reference masses and an F1-F2 stainless steel set for routine balance verification and controlled weighing checks.<\/p>\n
