Technology, Experience, Commitment...
Central Carolina Scale offers Rice Lake Weighing Systems calibration weights. RLWS has been supplying high-quality precision measurement products and services for over 30 years. The combination of world class manufacturing technology, an experienced staff of professionals, and a commitment to total quality enables Rice Lake Weighing to lead the industry in attaining a variety of quality certifications including ISO 9000 and ISO/IEC 17025.

Rice Lake Weighing Systems, an ISO 9001-registered company, has been a leader in the industrial scale and process-control weighing industry for 50 years. RLWS design, manufacture, and distributes the largest selection of load cells, weigh modules, and advanced instrumentation---over 20,000 products---to meet virtually every weighing requirement.

Rice Lake also manufactures precision calibration weights, including all ASTM, OIML, and NBS classes for balances and scales. Traceable and Calibration Certificates are available with every weight as well. The state-of-the-art metrology lab is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) and provides quality weight services, including recalibration and refurbishing of existing weights.


Technology
State of the art precision machining facility manufactures a full line of premier standards which conform to NIST, ANSI/ASTM and OIML.

Experience
Calibration technicians use primary and secondary mass standards directly traceable to NIST.
Weighing instruments and mass standards in Rice Lake's three metrology labs are meticulously maintained in accordance with ANSI/NCSL Z540-1.

Commitment
Strict adherence to exacting standards of quality, and an unequaled dedication to customer service means products and services will be right the first time, every time.

Rice Lake Weighing holds membership and participates in:
National Voluntary Laboratory Accreditation Program (Accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) for the specific scope of accreditation under Lab Code 105001-0
NIST Mass Measurement Assurance Program
Mid American Measurement Assurance Program
National Conference of Standards Laboratories
National Conference of Weights and Measures
NVLAP ISO/IEC 17025 (Replaces Guide 25)

Expanded laboratory capabilities will accommodate the very highest level of precision OIML Class E1. Many pharmaceutical companies, chemical labs and calibration houses require the E1 tolerance for their calibration standards. In order to supply customers with the necessary precision, Rice Lake invested in additional equipment to meet regulatory and uncertainty guidelines. Rice Lake provides customers with an industry leading four-day turnaround on all weight re-certifications, including Class E1 weights up to 10kg. Additionally, they now manufacture and certify Class E1 weights from 1mg to 5kg, purchased individually in kits, or as sets that include multiple weights in 5-2-2-1 configuration.

Precision Calibration Weight Catalog

Precision calibration weights, including all ASTM, OIML, and NIST classes, for balances and scales. We also provide special design weights, weight kits, and weight cases. Our precision calibration weights are designed specifically to assist you with ISO 9000 traceability requirements. (please note some prices may vary due to recent increases) Rice Lake offers cast iron weights and three (3) different designs of stainless steel weights. Due to varying configurations, the actual appearance of your product may be slightly different than shown on the catalog page. Serial numbers are available for an additional charge of $15.00 each when ordered without laboratory documentation. Individual leaf weights should be ordered with protective vial (individual leaf weights are for custom-designed kits)

Rice Lake offers several configurations for their weight sets. Class F weights have many set configurations to assist in calibration of scales; higher accuracy sets are available in 5-2-2-1 and 5-3-2-1. A standard set would be as follows:

5-2-2-1 (1) 50g, (2) 20g, and (1) 10g
5-3-2-1 (1) 50g, (1) 30g, (1) 20g, and (1) 10g

Custom sets are available as build to order to meet your specific requirements. Each weight set consists of the weights, case and / or small weight case (as appropriate).
