On Sale, Electrical-DC/Low Frequency DMM-719
Q4 Reduced - $300

6.5 Digit Digital Multimeter

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to calibration of a 6.5 digit Digital Multifunction Meter (DMM). 

This ILC/PT Kit contains a 6.5 digit DMM. Participants will use their lab practices to perform 17 measurements of voltage, current, 4-wire resistance, capacitance and frequency. Measurement values will be appropriate for calibration of similar devices.

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

On Sale, Force FORCE-203
Q4 Reduced - $300

1,000 lb Load Cell (Compression only)

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to measuring the mV/V output of a force transducer.

Participants will use their lab practices to perform 8 Load Cell force measurements from 100 lbf to 1000 lbf, and Load Cell Input and Output Resistance. The expected uncertainty of this 3 mV/V transducer is largely dependent on the calibration process and equipment used and will vary from 20 µV to 500 µV. 

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

Digital Micrometer and Caliper Set

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participants practices, training, and measurement uncertainty relating to calibration of a micrometer and a caliper.

This program provides both a micrometer and caliper in one set. The one inch micrometer requires five readings within its range. The caliper requires four readings over the six inch range. Measurement uncertainties reported are in the order of 0.0004 inch.

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

On Sale, Pressure PRESSURE-211
Q4 Reduced - $300

1,000 PSI Digital Test Gauge

The intent of this ILC/PT is to provide a means for participant laboratories to determine the appropriateness and effectiveness of participant practices, training and measurement uncertainty calculations relating to the calibration of a 1000 psi Digital Pressure Gauge.

Participants are asked to make a series of ten pneumatic pressure measurements between 100 and 1000 psi. The artifact resolution is 0.1 psi. The artifact accuracy specification is 0.1% FS from 20 to 100% of Full Scale, and 0.02% FS from 0 to 20% of Full Scale.

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

On Sale, Torque TORQ-514
Q4 Reduced - $300

Torque Wrench Set of 4 Wrenches

The intent of this ILC/PT is to provide a means for participant laboratories to evaluate the appropriateness and effectiveness of the their practices, training, and measurement uncertainties relating to the measurement of Torque by comparison of reported data and uncertainties to the data and uncertainties of other laboratories measuring the same data points on the same artifacts.

This ILC/PT Kit contains 4 Torque Wrenches: two Digital 1800 in*lb and 2 Flat Beam 600 in*lb Wrenches.

Participants are asked to use their lab practices to make Torque measurements at three Set Points per wrench for a total of 12 Set Points in the range of 100 to 1800 in*lb. Measurement values will be appropriate for calibration of similar devices. 

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.
