Improving productivity in a temperature calibration laboratory

Many calibration laboratories and instrument shops face the problem of delivering more accurate calibrations in less time and at lower cost. Although improving quality and performance while reducing cost is a difficult problem, it is also an old problem that manufacturers have been facing for years. Lean manufacturing, a concept pioneered by Toyota, offers an approach that may also benefit service as much as it does manufacturing.

Calibrating draft range pressure sensors

New application note shows how the PPC4 Controller/Calibrator calibrates this type of workload

Draft range pressure sensors are used to measure low gauge and differential pressure in a wide variety of industries, including hospitals, pharmaceutical production facilities, semiconductor and fiber optics manufacturing, and research and development. Most of the applications involve preventing an environment or manufacturing process from being contaminated. Because the pressures measured by these types of sensors are very low, calibrating them accurately can be a challenge.

Control charting laboratory references for quality control

What would you do if you had to develop control charts for 200 laboratory references? Control charts determine graphically if the current measured value falls within the expected range of values based on the history of the reference. It gives instant feedback to the operator that a measurement may be suspect and indicates if systems are in control. Control charts also allow managers to be notified if a measurement is outside the expected limits so they can take appropriate corrective action.

Calibration intervals, a manufacturer’s perspective

The analysis tools that are currently available for calibration intervals focus on setting intervals to achieve a desired reliability target. In a paper developed and presented at the 2009 Measurement Science Conference, David Deaver, manager of the standards laboratory at Fluke’s facility in Everett, Washington, USA, suggests that there is another perspective that these tools do not currently address – consequence cost or accumulated liability.
