NIST Calibration & Re-certification

The National Institute for Standards and Technology (NIST), U.S. Department of Commerce, recommends recalibration of standard leaks annually. Our partner lab uses NIST test 281901-12 to re-certify your standard leaks. As part of our annual service agreements, NIST calibrated leaks are exchanged with like scale leaks at the time of service to minimize your down-time. All leaks are labeled with serial number, leak rate, calibration date and provided with a written certificate of compliance.
