What Does an Instrument Mechanic Do?

An instrument mechanic services equipment used to take measurements, control systems, and perform other functions. This work requires specialized training in a given industry to understand how instruments are used, along with training on the equipment to work safely and productively. Facilities ranging from nuclear power plants to scientific labs need instrument mechanics to perform a variety of tasks. Hours can be irregular at times, as mechanics may need to work in emergencies to keep facilities running.

Part of this work involves routine maintenance. An instrument mechanic periodically inspects equipment and can choose to take it offline, taking it apart to check for common issues. Regular service visits provide time to replace components as they wear down, oil and lubricate, and perform other tasks to keep equipment running smoothly. Calibration can also be necessary, whether instruments take measurements, function as controls, or perform other tasks, as they need to be able to perform within acceptable tolerances.

When a facility needs to install new equipment, an instrument mechanic participates in this process. The mechanic can prepare and set up, and may also offer advice on various options to help an employer select the best equipment for a given situation. Once the new equipment is in place, instrument mechanics can test, calibrate, and prepare it for use by other personnel. This work can involve troubleshooting to integrate with other systems in the same facility.

Repairs can also be necessary as equipment breaks down or fails to function. Even with routine maintenance, problems can arise. The instrument mechanic responds quickly to find the source of the problem and develop an approach to fix it or replace the equipment if it is not repairable. This work can sometimes require high pressure environments when it involves key systems, as a company needs the equipment functional as soon as possible to stay operational or prevent a safety problem.

Some instrument mechanics train on the job. They work under the supervision of a skilled technician to acquire skills and learn how to work on a system. Others may attend formal training courses at a college or technical school to qualify to work with complex systems. They may join unions and professional organizations to access more opportunities for skill development. Wages and benefits for this kind of work can depend on the level of training received and the industry an instrument mechanic works in, as some demand more skill than others.
