Precision Recalibration Now Available in Europe!

Bios International is pleased to announce a new service center in the Netherlands that will streamline the processes of repairing and obtaining high-precision recalibration for clients in Europe.

Bios International’s gas flow calibrators -- featuring our proven DryCal technology -- guarantee an accuracy of 0.25%, or even 0.15% on some models. This precision is traceable to NIST and accredited by the National Voluntary Laboratory Accreditation Program (NVLAP).

To maintain calibration equipment functioning within this precise range, annual recalibration is recommended. Previously, clients sent their equipment for calibration to the Bios International lab in Butler, NJ, one of the world’s most accurate ISO 17025-laboratories, accredited to within 0.071% uncertainty.

Now, TPF Control in Wijchen, Netherlands can also service Bios International’s DC-1& DC-2, DC-Lite, Definer 220, and the Bios Defender 510 and 520 products, making reliable recalibration easily available in Europe.

“Having this capability in the Netherlands will save our customers both time and expense, ‘ says Scott Calvert, COO at Bios International. “We’ve eliminated the need for trans-Atlantic shipping of their valuable equipment, which reduces cost and downtime in the labs.”

For the convenience of clients throughout Europe, TPF Control offers service in several languages, including English, Dutch and German.

Flow Measurement Seminar to be Held at Bios

Lauren Padden
Director, Customer Relations

At last, a professional flow measurement seminar for flow measurement professionals!

Bios proudly announces our first-ever seminar in flow measurement science, led by Dr. George Mattingly, former leader of the NIST flow measurement group and the world's premier gas flow metrologist. Backed by inventor and president Harvey Padden and his team of Bios flow experts, this three-day event will be held in our ISO 17025-accredited laboratory in Butler, N.J., from June 13-15, 2007.

"For years our customers have asked us for top-level insights into the science of flow measurement and the latest, best thinking in flow technology," said Brad Padden, Managing Director of Bios. "With Dr. Mattingly's expertise and our experience, this promises to be a great opportunity to provide the kind of learning people can use every day."

The seminar will cover a wide range of carefully chosen topics, including (but not limited to) gas properties and flow equations, primary and secondary standards, calibration procedures, uncertainty practices and traceability, and how these relate to performing calibrations using Bios calibration products. There will also be open discussions of individual applications and other subjects of interest.

"Our intent is to provide the kind of practical help people can use to their jobs better," Padden added. "Virtually every industry is becoming increasingly dependent on accurate flow control. Best metrological practice is the key to optimum calibration results – and the bottom line."

While this initial seminar is by invitation only, Bios will post seminar-related elements to our website to educate all Bios customers as to how to obtain better application results and interpretations. Future seminar schedules will be posted on the site at a later date.  If you are interested in future Bios flow seminar events, please email sales@biosint.com.

500 slm DryCal® Technology Piston Prover Tested at NIST

Harvey Padden

President

At Bios, we’re constantly working to make high quality primary gas flow measurements faster, simpler and more precise. We’ve been pretty successful, as evidenced by our 0.15% Met Lab Series of high-speed piston provers. Now, we are developing a 0.15% DryCal Technology based prover for flows up to 500 slm.

As a cooperative research experiment, we took a prototype to NIST in order to test its linearity against their sonic nozzle flow standards. Taking a large number of readings at six flows from 10 slm to 500 slm, we established that our linearity agrees with NIST to about ± 0.05%. We did a second run and found that we could reproduce our results to better than ± 0.05% as well.

Since linearity was the largest variable in our overall accuracy, we’re now confident in our plans to extend the Met Lab Series to 500 slm. Please let us know if you want us to keep you informed of our progress and send you our technical papers when they are presented.

NEW Indestructible EPA flow transfer standard

Bradley Padden

Managing Director

Bios introduces drop-in replacement for performing ambient monitor flow calibrations using an orifice type flow transfer standard.

The Bios Definer™ 110 allows you to utilize the built in firmware for performing field flow audits for many Thermo® samplers and monitors including the Partisol® 2000, 2000-FRM, 2000-Audit, 2025, Dichotomous-2025 Samplers, and TEOM® Series 1400a, Series 8400N and 8400S monitors.

The Definer 110 (pictured above) is the latest application-specific product from Bios, delivering the ambient monitoring community an alternative to the fragile, glass-style orifice calibrators commonly used in performing audits of PM2.5, PM10 and TEOM air samplers.

                                            

Available in two flow ranges, the new Definer 110 features an unbreakable precision orifice manufactured with a zero coefficient expansion alloy – which means it can be used at any temperature and in any environment without affecting its accuracy. The Definer 110 is housed in an extremely durable, high-impact plastic body, complete with an integrated wind screen to reduce wind and eddy effects and enable it to be confidently used even in the most adverse field conditions. It’s also small and lightweight, so it’s easy to grab and go making it at home in field, where rough handling is the norm.  And, because it features Viton® seals throughout, your Definer 110 won’t degrade over time and exposure to common airborne pollutants.

Best of all, the Definer 110 is designed to be calibrated by the Bios Met Lab Series of high-precision primary standards. Each orifice is individually-calibrated at seven set points across its broad range, for the highest accuracy m and b constants.

As with all Bios products, Definer 110 calibrations are performed in our NVLAP-accredited ISO 17025, ANSI Z-540, NIST Handbook 150 gas flow calibration laboratory. No other EPA or environmental protection gas flow calibration laboratory can match our Scope of Accreditation.  Bios is also happy to perform calibrations and refurbishment services on other manufacturer's flow transfer standards so please ask us about our calibration offerings.  The new Definer 110 is a perfect choice when adding new orifice based flow transfer standards to your organization's ambient monitoring equipment inventory.
