Calibration of Dilute Moisture Meter by Coulometry

Phase meter calibration at NBS

National Bureau of Standards Gaithersburg, MD 20899 To provide a phase meter calibration service, a phase angle calibration standard has been developed at NBS. This standard is a signal. generator with two sinusoidal outputs and uses direct digital synthesis to generate the signals. The phase angle between the two sinusoids is determined by the input parameters in the calculation of the sets of...

In Line Flow-meter Calibration

Evaluation of the analytical performance of the coulometry-based Optium Omega blood glucose meter.

BACKGROUND The goal of diabetes treatment is maintaining near normoglycemia based on self-monitoring of blood glucose (SMBG). In this study, an evaluation of the analytical performance of the coulometry-based Optium Omega™ glucose meter designed for SMBG has been carried out. METHODS The assessment of precision and between-lot variability was based on glucose measurements in ethylene-diaminet...

Error Analysis of Nonconventional Electrical Moisture-meter under Simplified Conditions

An electrical apparatus for measuring moisture content was developed by our laboratory and uses dependence of electrical properties on water content in studied material. Error analysis of the apparatus was run by measuring different volumes of water in a simplified specimen, i.e. hollow plexiglass block, in order to avoid as many side-effects as possible. Obtained data were processed using both...

A Low Cost Field Usable Portable Digital Grain Moisture Meter with Direct Display of Moisture (%)

Moisture content of grain is one of the important parameters always considered when deciding the quality and price of grain, at the stage of harvesting, storage, processing and marketing. Grain having excess moisture content, if stored for long duration, will spoil due to insect/fungus infestation. Portable, field usable, and easy-to-use direct moisture (%) display Grain Moisture Meter is a nec...
