Cal-Pak is the ideal weight set to meet the USP-41 requirements. It has a maximum and 10% weight that meet the test weight requirements and a minimum weight to test the repeatability of the balance to determine the range.
Low magnetic susceptibility for less interference with weighing instruments
Finest grade of stainless steel available—offers uniform consistency and high resistance to corrosion for long-term mass accuracy
Low cost of ownership—recalibration costs lower for three weights versus an entire set
Cal-Paks are designed for routine checks and verification of your balances using 3 weights to span the entire range of the balance. The weights include the manufacturers recommended calibration weight, 10% of the calibration weight, and the minimum weight. The maximum weight is used to calibrate the balance externally, the mid weight is used to test the sensitivity of the balance and the minimum weight is the lowest possible weight that can be weighed on the balance. Cal-Paks add a higher level of confidence for calibration and verification over the entire range of your balance.
Cal-Paks are supplied in a case with accessories for care and handling of the weights including gloves and forceps. The Cal-Pak comes with a flash drive containing the electronic NVLAP* Accredited Certificate. This paperless system assures you can easily access and maintain your certificates. All components of the Cal-Pak and carrying case are linked through the use of a unique serial number allowing you to trace your individual weights to the appropriate NVLAP* Accredited Certificate and carrying case. Cal-Paks are available in ANSI/ASTM E617 Class 1 with a NVLAP* Accredited Certificate
