Companies often face the decision of whether to perform thermocouple calibration in - house using their own furnaces or to outsource the calibration to a third - party service provider. In - house calibration offers the advantage of immediate availability. You can calibrate thermocouples as soon as the need arises, without having to wait for shipping and turnaround time from an external provider. It also allows for greater control over the calibration process, as you can customize the calibration procedures to your specific requirements.
However, setting up and maintaining an in - house calibration furnace can be costly. There are the initial purchase costs, ongoing maintenance expenses, and the need to train staff. Outsourcing calibration can be more cost - effective for smaller companies that don't have the resources to invest in a full - fledged in - house calibration setup. Third - party providers also often have more extensive calibration capabilities and may be able to offer a wider range of calibration services. Each option has its pros and cons, and the decision depends on the specific needs and resources of the company.
