Sartorius Calibration Weights and Calibration Mass Sets

Individual Calibration Weights | Calibration Weight Sets

Sartorius Certified Calibration Weights:

NVLAP-accredited metrology lab
Meets or exceeds all ASTM Standards
1 mg to 5 kg calibration masses
Corrosion-resistant stainless steel
Custom weight sets available (phone 1-800-832-0055 for information)

Sartorius Calibration Weights are sold individually or as a 9-piece or 21-piece set with a Report of Traceabililty, and, for an additional nominal fee, with a certificate of Calibration.

Certificate of Calibration - The Certificate of Calibration report includes the nominal value and the conventional mass correction value for each weight certified. It also lists information on the standards the weights were compared against, including:

Identifying number
NIST test number
Date the standards were last calibrated
NVLAP laboratory code

Report of Traceability - At no additional cost, each Sartorius weight or weight set is supplied with a Report of Traceability. This report identifies:

Tolerance class
Type of construction
NIST test number
Date of applicable Sartorius primary standard(s)
Secondary set number
Includes technician's signature

Weight Class Standards

	Ultra Class U Standards - These mass standards provide great precision, ideal for use as reference standards to calibrate high-resolution analytical balances or to calibrate other weights. Ultra-mass tolerances are approximately two times the precision of ANSI/ASTM Class 1
	ASTM Class 1 - Appropriate for the calibration of high-precision analytical balances. They can also be used as reference standards to calibrate other weights
	ASTM Class 2 - Appropriate for calibrating high-precision toploading balances with readabilities ranging from 0.001 g to 0.01 g
