On Sale, Electrical-DC/Low Frequency CAPACITANCEs1409
Q2 Reduced - $300

Capacitors

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 the calibration of Fixed Capacitors.

This ILC/PT Kit consists of seven GenRad capacitors in the range of 0.001 µF to 0.5 µF. Participants are expected to be able to characterize each capacitor and report the measured values within their reported uncertainties. The frequency of test will be at 1 KHz.

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

Q2 Reduced - $300

RMS Clamp Meter

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 the calibration of a typical Clamp Meter.

This ILC/PT Kit contains a multifunction Clamp Meter. Participants will perform 10 measurements across functions of AC & DC Voltages up to 150 V, AC & DC Clamp Current up to 500 A, and Resistance. The artifact resolution is 0.1 Units. 

Participants are expected to be familiar with the operation and calibration of Multifunction Clamp Meters, have all necessary lab equipment, and have measurement uncertainties appropriate for calibration of similar devices.

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, Dimensional INSP-201
Q2 Reduced - $300

Inspection Parts - Pin, Aluminum Cast Artifact

The intent of this ILC/PT is to provide a means for the participant organization to evaluate the ability of a technician to make measurements using dimensional inspection test equipment. For this ILC/PT, micrometers, height gauges and calipers are the only inspection measuring equipment to be used.

This program involves the measurement of distances, locations, and the inside and outside diameters of an aluminum artifact with approximate dimensions 150 mm x 100 mm x 35 mm, and a set of Deltronic pins. Reference values are obtained by CMM measurement. The associated reference uncertainties are typically on the order of 2 µm to 3 µm. This program is very suitable for participants who measure machined work pieces using hand gages such as micrometers, calipers, height gages and indicators.

On Sale, Pressure PRESSURE-311
Q2 Reduced - $300

1,000 PSI Digital Pressure Gauge

The intent of this ILC/PT is to provide a means for participants to evaluate the appropriateness and effectiveness of their practices, training, and measurement uncertainty calculations relating to the measurement of Pressure, 0 to 1000 psi.
 

Participants are asked to perform 11 measurements, on increasing and decreasing scale from 0 to 1000 psi. Resolution of the digital artifact is 0.01 psi. Pressure medium - use only clean, dry non-corrosive gases (pneumatic). Manufacturer specification for artifact accuracy is 0.01% FS (FS = 1000 psi).

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

Proficiency Testing is Crucial

Proficiency testing plays a vital role in a lab’s quality assurance efforts and is required by major accrediting bodies. Routine testing can also benefit your lab in multiple other ways.

  • Maintain Accreditation
  • Ensure Technical Competence
  • Uphold Quality Standards
  • Monitor Lab Performance
  • Improve Processes
