This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard is designed for learners in the Measurement, Control and Instrumentation industry, and provides specific skills within the specialisation of an analyser mechanician.

A person credited with this unit standard will be able to:
  • Demonstrate an understanding of flame detectors.
  • Demonstrate an understanding of gas detectors.
  • Demonstrate an understanding of smoke detectors.
  • Demonstrate an understanding of heat detectors.

    This unit standard will contribute to the full development of the learner within the Measurement Control and Instrumentation environment and related fields, by providing recognition, further mobility and transportability within the field of Manufacturing Engineering and Technology. The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and upliftment of candidates.

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The following knowledge, skills attitude and/or equivalent:
  • Communication and literacy at NQF Level 2.
  • Mathematical Literacy at NQF Level 2.

    Learners are also assumed to have attained competence in the NQF Level 2 National Certificate: Measurement, Control and Instrumentation. 
    		•

    UNIT STANDARD RANGE 
    For the purposes of this Unit Standard:
  • Detection equipment refers to smoke, gas heat and flame detectors.
  • Analysers are categorized per methods of detection and could include but is not limited to the following:
    > Catalytic Combustion, Electrochemical, Oxygen in gas, Dissolved oxygen, Titration, Infrared or Ultra Violet spectrum, Moisture measurement, Density, Thermal method, Turbidity, Chromatographic, Photometric, telemetry and colorimeter.
  • Routine maintenance could require the removal of the equipment or parts thereof, isolation, calibration, installation and operationalisation.
  • Safety precautions include the use of all personal protective equipment, electrical and fire protection.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
