INDuSTRY PRODuCTS Bonneville power Selects Web-Based Energy Monitoring Systems from Onset nset Computer Corporation has announced that the Bonneville Power Administration (BPA), a non-profit federal agency under the US Dept. of Energy serving the Northwest, has purchased 14 Webbased energy monitoring systems for measuring the energy performance of packaged rooftop HVAC units on commercial buildings. BPA has installed the 14 HOBO® U30 Remote Monitoring Systems in various service territories throughout the Pacific Northwest to collect data on HVAC unit energy consumption and building thermostat call settings. Each 15-channel monitoring system enables multiple HVAC units to be monitored at once, and the data is made available on the web via Onset’s HOBOlink£ Web site. “The data is being analyzed and will assist in determining the energy savings associated with performing advanced maintenance services to packaged rooftop HVAC units,” said Erik Boyer, an engineer with BPA. “Ultimately, this information will help us determine the amount of money BPA will offer businesses to perform these services in the Northwest.” According to Boyer, the monitoring equipment also helps ensure that the HVAC systems were connected properly and has enabled BPA to investigate system performance. BPA will be funding another project this summer aimed at measuring the energy performance of packaged rooftop HVAC units and is planning to utilize O the Onset monitoring systems to collect the energy performance data.

Dickson 800.323.2448 Addison, IL www.dicksondata.com What is “Before” Data? from Dickson efore data documents the accuracy of your data logger or chart recorder before it is calibrated. When your instrument is re-calibrated by Dickson it is returned to original specifications. You cannot obtain “before” data once an instrument has been re-calibrated. “Before” data is required for ISO 17025/A2LA Accredited NIST Traceable calibrations N450 Compliance-Max). “Before” data is required to accurately determine applicationspecific calibration schedules (N550 Before & After or N450 Compliance Max). Many regulations (e.g., QS 9000, FDA 21 CFR Part 11, CDC Vaccine recommendations, among others) require notifications of outof-tolerance conditions creating a need for “before” data. In addition, quality control manuals and standard operating procedures (SOP), such as those specifying standards for various automotive parts, require the same information. If your application is subject to liability claims, the only way you can demonstrate due diligence in maintaining instruments’ accuracy is by including documentation of “before” calibration data and step-by-step determination of required calibration schedules. “Before” Calibration Data is the only way to document that your B Excel Scientific, Inc. Excel Scientific’s New 50 mL Serological pipet Offers Improved Accuracy and Sterility xcel Scientific’s redesigned 50 mL Serological Pipets are constructed from high clarity virgin polystyrene. They are certified RNase-, DNase-, pyrogen-free, and non-cytotoxic. The smooth non-welded tip eliminates sample hang-up, leakage, and breakage. A 3 mm I.D. opening minimizes shear. Sterile, individual one-side-paper, one-side-plastic packaging is easily opened by peeling or pushing through the paper. A colored woven polypropylene plug provides easy size identification. There are forward and reverse 0.5 mL graduations with printed volumes at 1 mL intervals and negative graduations to -5.5 mL. Accuracy is ± 1.5% and sterility better than 10-6.
