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.
• State of the art precision machining facility manufactures
a full line of premier standards which conform to NIST, ANSI/ASTM
• 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
• 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 and 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.
Calibration Weight Catalog
Below you will find our
test weights in pdf files including prices and certificate prices. This includes
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 when ordered without laboratory documentation. Individual leaf weights
should be ordered with protective vial (individual leaf weights are for custom-designed
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:
(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
