Real-Time Detection Systems

This PDC provides the knowledge and helps develop the skills needed to train field persons in the operation of Portable Gas Detection Instrumentation, focusing on delivering training to meet the body of knowledge requirements of the AIHA Registered Operator credential. At the end of this PDC, participants will be prepared to train users of the portable 4-Gas Meter and/or the combo 4-Gas Meter/Photoionization Detector (PID).

Value Added:
By your participation in this PDC, you will have completed the first stage towards becoming authorized trainers for the 4-Gas Detection Registry Preparation course.

Learning Aids:
Participants must bring 4-Gas or 4-Gas/PID detection equipment.

Upon completion, the participant will be able to:

  • Discuss the difference between calibrating to methane vs. pentane
  • Identify sensor poisons
  • Recognize cross sensitivities to sensors
  • Demonstrate the application of this instrument in measuring toxic contaminants
  • List instrument limitations
  • Cite basic sensor theory and how they work
  • Lead discussions in this area with field personnel
  • Demonstrate proper calibration and use of a variety of portable gas detection equipment


  • Module 1 – Instrument overview
  • Module 2 – Review of basic chemical principles
  • Module 3 – Oxygen sensor technology
  • Module 4 – Combustible gas sensors
  • Module 5 – Electrochemical sensors
  • Module 6 – Photoionization detector
  • Module 7 – Calibration of the instrumentation
  • Module 8 – Datalogging
  • Module 9 – Guidelines for selection

Transfer of Knowledge:
Instructors will evaluate participants understanding of the materials presented based on:

  • Post course test
  • Hands-on demonstrations and practicum
  • Practice exercises
  • Workshops
  • Group activities
  • Interactive games
