How to Submit a Calibration Request
Step 1 - Identify the Calibration Points Required
You can refer to our price list below to help you decide which type of calibration you require. If you know what you would like or already have had a quote from us, please go straight to Step 4 to send your instrument for calibration. If you’re not sure what you need,
see Step 2.
Step 2 - Get a Quote (Optional)
If you need help deciding what type of calibration to get, or you need something that is not on our price list, please fill out the Bespoke Calibration Request form below. To help us process your request quickly, please tell us your instrument type, whether it has a probe or an internal/external sensor, and which temperature points you require (if you know what you would like).
Step 3 - Receive Your Quote (Optional)
Once we have received your bespoke request, a member of our team will get back to you. If you've included enough information, you may get a quote straight away. If not, don't worry, our team have plenty of experience and will help you understand what it is that you need. They will include the quote once they have clarified your points.

Temperature & Humidity Recalibration
To keep your equipment accurate and reliable, regular recalibration is essential.
How often you should recalibrate depends on the purpose of the thermometer, how frequently it's used, and any relevant regulatory guidelines. Generally, it’s a good idea to check accuracy at least once a month and recalibrate a few times a year.
At ETI, we provide a quick, precise, and hassle-free recalibration service for any thermometer or hygrometer, even if you didn't buy it from us. Our service is flexible, allowing you to choose the number of checkpoints and the specific temperature ranges you need.
To get started, simply review our price list or complete our Returns Form.
If you are requesting a calibration because you received a reminder letter from us, please make sure to select ‘Calibration Reminder’ as your Reason for Return on the form. For all other calibration requests, please select the most applicable option.
