Calibrator group shot Confidence in Calibration for your Gas Flow Devices
You are on the right page if you want to maintain the integrity of your air monitoring programs and stay compliant with quality management systems. SKC‘s ISO/IEC 17025:2005 accredited calibration laboratory provides fast, reasonably priced calibration and certification services for most types of flowmeters. Choose from two service levels: NIST Traceable Service for annual calibration of pump flowmeters or ISO-IEC 17025:2005 Service for devices used as standards in labs. Learn more in this brochure!

Items marked with a * are required :

Gas Flow Device (required information)
Unit indicated below is functional
Unit indicated below is Non-functional

Defender (510L, 520L, 530L, 510M, 520M, 530M)
Mass Flowmeter (to 10 L/min)
Dual-ball Rotameter
Soap Film Flowmeter

Certification Level Specified (required information)

NIST Traceable Calibration: This is the standard calibration procedure for flowmeters used in air sampling and similar procedures.

ISO/IEC 17025:2005: This procedure offers NIST Traceable Calibration as above with the addition of uncertainty values for measured parameters during the test at each reported result. (Only gas flow rate calibration is available for Defender 520/530 models.)

Custom Service: This option offers a customizable service and/or certificate to meet your specific needs.

Flows to be Calibrated (optional information):
Standard Calibration flow rates are:
  • 1, 2, 3, 4, and 5 L/min for high flow
  • 750 ml/min, 1, 2, 4, and 5 L/min for chek-mate
  • 100, 200, 300, 400, and 500 ml/min for low flow
List any additional flow rates required.

SKC will contact you with pricing for additional flow rates before proceeding.

Frequency of Calibration Specified by User (required information):

Annual Calibration: 1 year from last calibration date

Every 2 years: 2 years from last calibration date

Other Frequency: Custom calibration frequency to meet your specific needs

This information will be noted on documentation and reported on the calibration label.

For Rotameter Calibrations Only (optional information):
Rotameter readings will be corrected to standard temperature and pressure.
If non-standard temperature and pressure are desired by the user, please indicate:

Standardization Temperature (if other than 20 C)

Standardization Pressure (if other than 1013.25 mbar)

Calibration Service Time (required):
Standard 10 to 15 business days
Expedited service available. SKC will contact you with additional fee information
