Gas Monitors

Training Provided by Abhisam Software This training program equips you with the knowledge necessary to understand, design, specify, select and implement gas monitors. These gas monitors are used in almost all industries like Oil & Gas, Petrochemical, Chemicals processing, Shipping, Semiconductor fabrication, Power Generation, Steel plants and the like. Gas monitors are used in these industries to detect and warn the presence of explosive and toxic gases that can harm humans and the environment. Gas monitors are also used to monitor other essential gases like Oxygen, in confined spaces. The program covers this subject in FOUR learning units. These units are Gas Monitor Fundamentals, Types of Gas Monitors, Gas Monitoring Systems and Gas Monitor Installation, Calibration and testing. The course uses graphics, animations, real life plant photos and videos to make this an enjoyable experience. If the learner passes the online examination, a certificate of accomplishment is granted.

Gas Monitors The course is divided into FOUR Learning Units. Each Learning Unit consists of several lessons. Each lesson contains several topic pages and sometimes, an exercise or two. The course outline is given below.
