Oizom Multi- Level Calibration System For Environment Monitoring Solution
In laboratory calibration, assembled Oizom devices POLLUDRONE, DUSTROID, ODOSENSE, WEATHERCOM are calibrated with pure air and calibration gases with high range concentrations. In a laboratory setting, zero and span calibration are performed in order to validate the manufacturer’s sensor calibration and determine the sensor offset or gain error if any. In order to perform zero and span ...

A neural network implemented microcontroller system for quantitative classification of hazardous organic gases in the ambient air
In this study, a microcontroller-based gas mixture classification system is proposed to use real-time analyses of the trichloroethylene and acetone binary mixture. A Feed Forward Neural Network (FFNN) structure is performed for quantitative identification of individual gas concentrations (trichloroethylene and acetone) in their gas mixtures. The phthalocyaninecoated Quartz Crystal Microbalance ...

Achieving accurate gas flowmeter calibration
The calibration of gas flowmeters and/or flow controllers is one of those important, inescapable tasks that can be something of a nuisance to the engineer responsible for getting the job done. Sending flowmeters back to the manufacturer for recalibration can be expensive and cause production delays. For this reason, most big users of flowmeters opt for in-house calibration. This approach is often ...
