Temperature calibration is an important step in achieving accurate lab results, but it can be confusing to someone who has never done it before. This comprehensive guide will walk you through the process of calibrating your temperature, including the equipment you’ll need and the precautions you should take to ensure your results are as accurate as possible. The chart below lays out the equipment you’ll need and the steps you’ll take to achieve an accurate calibration; click on each point for more information about how to proceed with your calibration. Happy calibrating!
What is temperature calibration?
Accurate temperature monitoring is a critical component of proper machine maintenance. Whether you’re working with semiconductors, lab equipment, or industrial machinery, it’s essential that you can trust your temperature readings. This guide will help you understand exactly what temperature calibration is and how it works. What do I need for temperature calibration?: A lot of factors go into calibrating your thermometer. For starters, you’ll need a stable source of heat and a thermometer (or thermocouple) that’s designed for use in extreme temperatures.
Why should you calibrate your temperature?
Most thermometers are only accurate to about 1°C. For some processes, even 0.5°C might be too large an error – in these cases it’s vital that you calibrate your thermometer regularly, so you can be sure that you have a good idea of how hot or cold something is. If you don’t know what temperature something is, then how can you work out if it’s safe? How do I calibrate my thermometer?: First, make sure your thermometer isn’t damaged (for example, if there are any cracks). Next, fill a pot with water and bring it to a boil. Once boiling point has been reached (this will take some time), turn off the heat and let it sit for 5 minutes.
How do you calibrate your temperature?
Thermal calibration refers to a procedure in which your thermometer is checked against an NIST-traceable reference standard and calibrated accordingly. This ensures that your device will read correctly once you deploy it for use, especially if you’re using a digital or infrared thermometer. Calibration is a simple procedure and just involves placing your sensor into boiling water, ice water or other solution of known temperature.
Most instruments come with instructions on how to calibrate them and there are also plenty of resources online as well. The only thing you need to make sure is that your instrument can be recalibrated before deploying it out into field conditions. Some non-contact sensors are designed to be disposable, while others can be re-calibrated multiple times; check with your manufacturer for guidance on how many times yours can be recalibrated before replacement becomes necessary.
Temperature Calibration is critical, but in order for your temperature reading to be accurate, you must calibrate it with a thermometer that has been calibrated. Make sure it’s giving an accurate reading and not off by just one or two degrees and always double-check your thermometer, even if you have checked it multiple times beforehand.
