Instrument Skills Appreciation in Process Measurement


To enhance the skills and knowledge of staff with regards to process instrument measurement.

A process or engineering background or instrument personnel required to update their skills.

Course Duration
5 days.

Maximum Number
4 persons.

Training Aids
Lecture notes, audio visual presentations, models and large plant simulator.

Each course participant may, if required, complete a series of tests to determine achievement of objectives.

On successful completion of the course candidates will receive a NETA certificate. The certificate will be sent directly to the delegate or their sponsor company.
