Henry Troemner Electronic Balance Calibration Weights
To get all the
accuracy your electronic balance and/or scale provides, you need
to perform routine calibrations and verifications using precision
calibration weights. Troemner's Stainless Steel Electronic Balance
Calibration Weights are intended for this purpose and are available
in Troemner UltraClass and ANSI/ASTM Classes 1, 2, 3 and 4 in sizes
ranging from 10 g to 30 kg. Weights are available in a cylindrical
design up to 5 kg and a stackable grip-handle design from 5 kg to
30 kg for all necessary testing, calibration and adjustment of electronic
scales and balances. All ANSI/ASTM E617 class weights meet or exceed
specifications for tolerance, construction, surface finish, and
magnetism as outlined in ANSI/ASTM E617. Weights 5 kg and below
are supplied in protective cases.
Why UltraClass?
Troemner UltraClass weights are the most precise type II two-piece
weights available with weight tolerances 50% greater than ANSI/ASTM
E617 Class 1 tolerances. UltraClass weights combine high precision
with the advantage of two-piece construction (1 g and larger) avoiding
costly replacement issues associated with one-piece weights.
Suggested
Applications
It is recommended that the weight selected to calibrate a balance
and/or scale have a tolerance small enough as not to be detected
by the balance and/or scale. Troemner recommends the tolerance of
a weight selected for calibrating a balance and/or scale is no more
than 1/3 of the readability or precision of the balance and/or scale
being calibrated. If this cannot be achieved, it is suggested that
a Class 1 or Troemner UltraClass Electronic Balance Calibration
Weight with a NVLAP certificate be ordered which provides the actual
mass value for the weight which reduces measurement uncertainty.
Electronic Balance
Calibration Weights can also be used to check or verify the accuracy
of your balance and/or scale between calibrations. It is recommended
that the user check a balance and/or scale prior to each use. Keeping
the weight at or near the balance and/or scale keeps the weight
at the same temperature as the equipment.

Weight Calibration Certificate |
NVLAP
Weight Calibration Certificate is a detailed, multi-page weight
certificate designed to meet all of your ISO (including ISO/IEC
17025), FDA, GMP, GLP, DOD, ANSI/NCSL Z540-1, and nuclear requirements.
The NIST-administered National Voluntary Laboratory Accreditation
Program (NVLAP Lab Code 105013-0) approves all procedures for
this detailed weight certificate. The measurement process follows
the recommendations of NIST Handbook 145.

| Traceable
Weight Certificate |
Traceable
Weight Certificate - designed for those laboratories and companies
that require traceability, but do not need to meet any stringent
regulatory requirements. In contrast to NVLAP or UKAS calibration
procedures, the Traceable Weight Certificate measurement process
is based on a single standard and utilizes one series of comparisons.

| Statement
of Accuracy |
New
weights and weight sets supplied without weight certificates
come with Troemner's Statement of Accuracy which provides the
nominal value, type of weight, material / density and weight
class. Note: There is no NIST traceability supplied with
this statement. The Statement of Accuracy is not suitable for
quality or regulatory requirements. Troemner's Statement of
Accuracy is only available with the purchase of new weights.
Troemner's Brass Weights are not supplied with a Statement of
Accuracy.
