LK Industries ISO/IEC 17025 Lab: Accreditation Process Creates Higher Standards

Houston, Texas; December, 2016

Earlier this year, L-K Industries proudly opened its newly accredited ISO/IEC 17025 Lab as a result of acquiring Miller-Weber, Inc. Known fondly as the New York thermometer company, Miller-Weber joined L-K Industries, renowned oil testing equipment manufacturer, and relocated to Houston, Texas to become an official part of the L-K Industries’ family. The alliance results in L-K’s ability to offer both manufacturing and accredited calibration under one roof: a unique and highly desirable combination.

Established jointly in 1999 by the International Standards Organization (ISO) and the International Electrotechnical Commission (IEC), ISO/IEC 17025 is one of the most well respected accreditations for testing and calibration laboratories. Accreditation is limited to labs that are willing to undergo a rigorous third-party assessment. This process creates an uncompromising standard of quality.

The company’s focus on accreditation and standards ensures that customers have a high level of confidence in the calibrations performed by Miller-Weber Texas (MWTX).  Key attributes include:

  • established traceability of its own measurement standards and measuring instruments to the International System of Units (SI) by means of an unbroken chain of calibrations;
  • application of procedures to estimate the uncertainty of measurement for all calibrations performed, and the assurance that the calibration uncertainties are sufficiently small so that the adequacy of the measurement is not affected;
  • an ASTM Fellow on staff as the Laboratory Technical Manager;
  • an unblemished inspection record with zero findings in the laboratory’s history.

In addition, each calibration certificate issued by MWTX contains the measurement results, the measurement uncertainty, and/or a statement of compliance with an identified metrological specification. For clients, the most important outcomes of L-K’s efforts are the exponential benefits they receive. “Beyond the international distinction, recognition, and inherent credibility gained from the accreditation process,” says Owner/Engineer Eric Calderon, “are the benefits for those we serve. We can confidently offer those who purchase our merchandise a testing and calibration service that’s truly unique. For customers who demand a higher standard, we can deliver.” The lab certifies temperature from – 80 to 405 degrees, density from 0.6250 to 1.910 relative density (SG), gravimetric calibration up to 100 ml, and rotational speed up to 6,000 rpm.

L-K Industries manufactures and calibrates a full range of liquid and glass thermometers, hydrometers, and centrifuge tubes. They’re already providing thermometers to the petrochemical industry and local hospitals, and look forward to expanding into the healthcare and agricultural markets within the next few months.

L-K Industries has enjoyed 86 years manufacturing centrifuges and related oilfield testing equipment, and continues to develop ground-breaking technology under the helm of Owner/ Engineer Eric Calderon. Recent acquisition of Miller-Weber of Texas allows them to furnish clients with a complete array of thermometers, hydrometers, and related glassware, and an accredited on-site laboratory secures their position in the oil industry and the Houston community.
