RICE LAKE WEIGHING SYSTEMS

The Rice Lake Weighing Systems calibration weights supplied by 3G Electric are Class 7, as indicated by the product specifications. Class 7 is a metrological accuracy class defined in OIML R 111, representing the lowest accuracy category for weights used in less demanding verification tasks. These weights are suitable for routine scale calibration and performance checks where high precision is not required. For applications needing tighter tolerances, other classes are available from Rice Lake. The class is marked on the weight or its certificate, and buyers should confirm the required class for their specific scale and regulatory context.

Rice Lake Class 7 calibration weights are available in cast iron and aluminum. For example, the slotted weights with part numbers 10152, 10154, 10156, 10168, and 10189 are made of cast iron, while the hook-style weight with part number 10188 is made of aluminum. Cast iron offers durability and stability for heavier weights, while aluminum provides a lighter option for smaller masses. The material affects the weight's density, corrosion resistance, and handling characteristics. Buyers should select the material based on environmental conditions and the frequency of use in their calibration procedures.

Slotted calibration weights have a slot or groove that allows them to be placed on a hanger or a knife-edge, typically for use with balance scales. Hook calibration weights have a hook or ring for hanging from a scale's load receptor or a hook. Both configurations are available in Class 7 accuracy from Rice Lake. The choice depends on the type of scale being calibrated: slotted weights are common for two-pan balances, while hook weights are used with crane scales, hanging scales, or other instruments that accept a suspended load. The nominal mass and material also vary by model.

Rice Lake Class 7 calibration weights are available in a range of nominal masses. From the products supplied by 3G Electric, examples include 0.5 lb (part numbers 10152 and 10154), 1 lb (10156 and 10168), 1.5 lb (10189), 7 oz (10188), 17 oz (10186), and 21 oz (10187). These weights can be used individually or in combination to verify scale accuracy at specific test points. The nominal mass is typically marked on the weight. Buyers should select masses that correspond to the scale's capacity and the desired test load. Custom sets and other masses may be available from Rice Lake.

Rice Lake calibration weights are used to verify and adjust the accuracy of industrial scales and balances. The process involves placing a known mass on the scale and comparing the displayed value to the nominal mass of the weight. If the deviation exceeds acceptable limits, the scale is adjusted according to the manufacturer's procedure. Class 7 weights are suitable for routine checks and non-critical applications. For regulated or high-precision environments, higher-class weights may be required. The weights should be handled carefully to avoid damage or contamination that could affect their mass. Regular recalibration of the weights themselves is recommended.

3G Electric offers technical specification assistance and quotation services for Rice Lake Weighing Systems products, including calibration weights. Buyers can request help with selecting the appropriate nominal mass, accuracy class, and configuration for their scale calibration needs. 3G Electric supplies these products globally and can provide manufacturer part numbers and specifications to ensure compatibility. For application-specific questions or calibration procedures, buyers should consult Rice Lake's documentation or a qualified metrology professional. 3G Electric does not provide on-site calibration services but can facilitate access to the necessary equipment.
