What makes our thermocouple calibration
so special?
Transparency through inhomogeneity testing
For thermocouples – especially base metal types – we perform a full inhomogeneity scan. This gives you:
A realistic assessment of measurement uncertainty
Traceable and documented results
Confidence that your sensor performs as specified
With us, you don’t receive the smallest possible measurement uncertainty, but the correctly determined one – for complete audit security and full confidence in your measurement chain.
New: Digitally Signed Calibration Certificates with Official Accreditation Symbol
We now provide our calibration certificates with a digital accreditation symbol officially introduced by DAkkS (German Accreditation Body). This means your calibration documents are digitally and legally signed, featuring a tamper-proof and officially recognized seal.
Your Benefits at a Glance
- Tamper-proof and verifiable
The digital signature can be verified electronically – preventing any form of manipulation. - Legally binding and internationally recognized
The digital symbol confirms the validity and authenticity of the calibration certificates – even without a printed copy. - Digitally available – anytime & anywhere
You receive your calibration certificates as PDF files via our cloud solution – securely archived and accessible at any time. - Future-proof & audit-compliant
Ideal for digital workflows, ISO-compliant documentation, and quick access during audits.

What are the costs involved in calibrating thermocouples?
When you have a thermocouple calibrated in our accredited laboratory, the total cost is always made up of two components:
- Basic calibration cost
- Cost per calibration point
Additionally, depending on the temperature range, liquid nitrogen costs may apply.
1. Basic Cost (mandatory for every calibration)
- kk-1492 – Basic cost for noble metal thermocouples: €145
- kk-1493 – Basic cost for base metal thermocouples: €145
The basic cost includes:
- Issuing an accredited calibration certificate according to DIN EN ISO/IEC 17025 (DAkkS)
- Stabilization and comparison calibration against our reference standards
- Inhomogeneity testing (for noble metal thermocouples including graphical analysis)
- Documentation of the achievable measurement uncertainty
2. Cost per Calibration Point
Depending on the temperature range in which your thermocouple is used, suitable calibration points can be selected.
We perform calibrations with a minimum of 3 calibration points – 5 points are recommended for a reliable characterization.
| Code | Calibration Point Range | Price |
|---|---|---|
| kk-1494 | -80 °C to +230 °C | €105 |
| kk-1495 | +231 °C to +1200 °C | €130 |
| kk-1497 | -196 °C (liquid nitrogen boiling point) | €130* |
| kk-1496 | -180 °C to -81 °C | €195* |
* Additional nitrogen costs apply (see below).
3. Liquid Nitrogen Costs (for low-temperature calibrations only)
For calibrations in the cryostat or at -196 °C, the use of liquid nitrogen is necessary. This is charged per calibration:
| Code | Description | Price |
|---|---|---|
| kk-1477 | Liquid nitrogen (50 L) for cryostat | €490 (for -180 °C to -81 °C measurements) |
| kk-1478 | Liquid nitrogen (10 L) for -196 °C calibration | €100 |
4. Example Calculation
A typical industrial thermocouple could be calibrated at 5 calibration points, for example:
0 °C, 100 °C, 300 °C, 600 °C, 1000 °C
The total cost would consist of:
- €145 basic cost (kk-1492 or kk-1493, depending on type)
- 5 × €105–€130 per calibration point
With a selection of 3 calibration points (e.g. 0 °C, 100 °C, 600 °C), the cost is approx. €485 net.
5. Quantity Discounts
If multiple thermocouples are calibrated at the same temperatures at the same time, we offer attractive discounts:
- From 5 units: 15%
- From 10 units: 30%
Summary
The total cost of a calibration depends on:
- The one-time basic cost (kk-1492 or kk-1493)
- The number and selection of calibration points (kk-1494 to kk-1497)
- If applicable, nitrogen costs (kk-1477, kk-1478
