- Professional 3-Point Thermocouple Calibration Added to Your Order
- Performed by Our ISO/IEC 17025 Accredited Partner Laboratory
- Choose Commercial NIST-Traceable or Fully Accredited (ISO 17025) Calibration
- Calibrated at the Three Temperature Points Listed in the Table Below
- Custom Calibration Points Available on Request
- Ships with a Calibration Certificate, Ready for Your Quality Records or Audit
- Available on Any IOThrifty Thermocouple, Done at the Time of Purchase
Add a professional calibration to any thermocouple you order from us and receive it ready to use, with documented accuracy you can trust. The calibration is a standard three-point calibration performed by our ISO/IEC 17025 accredited partner laboratory, carried out at the time of purchase so your thermocouple arrives already calibrated and accompanied by its certificate. There is nothing to send away and no downtime: you simply add the calibration to your thermocouple, and we handle the rest before it ships.
Choose the Level of Calibration You Need
We offer two options so you only pay for what your application requires. A commercial NIST-traceable calibration provides measurements traceable to national standards and a calibration certificate documenting the results at each point, which is ideal for general process use, internal quality checks, and routine verification. A fully accredited ISO/IEC 17025 calibration is performed under the laboratory's accreditation scope and includes reported measurement uncertainties, making it the right choice when you need third-party accredited results for regulated industries, formal audits, or a documented quality system.
Standard Three-Point Calibration
Each calibration is performed at three temperature points, which are listed in the table below. These points are chosen to bracket the temperature range most thermocouples are used in, so your sensor is verified across the span that matters for your process. If your application calls for different temperatures, custom calibration points are available on request. Just let us know the points you need and we will arrange them with the lab before your order ships.
Calibrated at the Time of Purchase
Because the calibration is completed as part of your order, there is no separate shipment, no round trip to a lab, and no waiting to put your thermocouple into service. Add the calibration when you buy the thermocouple, and it will be calibrated, certified, and shipped together as one order.
What You Receive
Your thermocouple arrives with a calibration certificate that documents the reading at each of the three points and the traceability of the measurement. Accredited ISO/IEC 17025 certificates additionally include the measurement uncertainty at each point and the accreditation reference, giving you audit-ready documentation for your records.
Frequently Asked Questions
Which calibration should I choose?
If you need documented, traceable accuracy for general use and internal quality control, the commercial NIST-traceable calibration is usually sufficient. If you operate in a regulated industry or need accredited results with stated uncertainties for audits or a formal quality system, choose the accredited ISO/IEC 17025 calibration.
Can I calibrate at different temperatures than the three listed?
Yes. Custom calibration points are available on request. Contact us with the temperatures you need and we will confirm them before your order is processed.
Does this add to my delivery time?
Yes. Because the calibration is performed by our partner lab before your thermocouple ships, it typically adds 1 to 2 weeks of lead time. If you have a deadline, let us know and we will do our best to accommodate it.
Can I add this to a thermocouple I already own?
No. This calibration service is only available for thermocouples purchased through IOThrifty and is performed on the sensor you order with it.
What if I need more or less points?
Not a problem, reach out to us and we'll work through pricing that fits your needs
