Product Description
Close the gaps in your calibration program with single OIML weights from 1 mg to 50 kg in Classes E1, E2, F1 and F2. They let you replace a lost or out-of-tolerance weight, add a test load for linearity checks, or build an application-specific set for one balance. E-class weights work as reference standards, and F-class weights are made for regular in-house verification.
This listing is for OHAUS item number 30390877: OIML Class F2 Calibration Weight, 50 kg, Two-Piece, with Accredited Calibration Certificate. Design follows OIML R111 practice: cylindrical bodies with a tapered handling neck, polished surfaces and recessed bases for gram and kilogram values, and flat milligram weights with one end turned up. Materials are Alloy 8 or 316 stainless steel for larger values and 304 stainless steel or aluminum for milligram values. One-piece and two-piece construction and the certificate type (ISO/IEC 17025 accredited or none) are shown in each product name. Every weight ships in a protective case to guard against contamination and handling damage. Order it from LIGHT LABS alongside the rest of your OHAUS balances, weights and lab equipment.
