What Makes Our Thermocouple Calibration So Special?
Transparency Through Inhomogeneity Testing
For thermocouples – especially base metal variants – we perform a complete inhomogeneity scan. This provides you with:
Realistic assessment of measurement uncertainty
Traceable, documented results
Assurance that your test item delivers what it promises
With us, you get not the smallest possible, but the correctly determined measurement uncertainty – for full audit security and confidence in your measurement chain.
New: Digitally Signed Calibration Certificates with Official Accreditation Symbol
Recently, we have been issuing our calibration certificates with a digital accreditation symbol, officially introduced by the DAkkS (German Accreditation Body). This means your calibration certificates are legally validly digitally signed and bear a tamper-proof, recognized seal.
Your Advantages at a Glance
- Tamper-proof and verifiable
The signature can be checked electronically – preventing manipulation - Legally binding and internationally recognized
The digital symbol confirms the validity and authenticity of the calibration certificates – even without a paper printout. - Digitally available – anytime & anywhere
You receive your calibration certificates as a PDF via our cloud solution, securely archived and accessible at any time. - Future-proof & audit-compliant
Ideal for digital processes, ISO-compliant documentation, and quick access during audits.

Klasmeier Cloud Digital Archive:
Calibration documents quickly and easily accessible
The Klasmeier Cloud – the perfect filing system for all calibration documents. On all devices calibrated by Klasmeier, you will find a QR code that provides quick and easy access to our digital archive.
Particularly practical: In addition to all calibration documents, you’ll also find the contact details of the respective Klasmeier contact person there. This way, even in five or more years, you can find the desired information with a single click if you have questions about your calibrated product.

What are the costs for calibrating thermocouples?
If you have a thermocouple calibrated in our accredited calibration laboratory, the costs are always composed of two components:
- the basic costs for calibration
- the cost per calibration point
Additionally, depending on the temperature range, nitrogen costs may apply.
1. Basic Costs (Mandatory Component of Every Calibration)
- kk-1492 – Basic costs for noble metal thermocouples: €150
- kk-1493 – Basic costs for base metal thermocouples: €150
The basic costs include:
- Creation of the accredited calibration certificate according to DIN EN ISO/IEC 17025 (DAkkS)
- Stabilization and comparison calibration against our reference standards
- Investigation of inhomogeneities (for noble metal thermocouples incl. graphical evaluation)
- Documentation of the achievable measurement uncertainty
2. Cost per Calibration Point
Depending on the temperature range in which you use your thermocouple, suitable calibration points can be selected. We perform calibrations with a minimum of 3 calibration points – 5 calibration points are recommended for reliable characterization.
- kk-1494 – Calibration point -80 °C to +230 °C: €110
- kk-1495 – Calibration point +231 °C to +1200 °C: €135
- kk-1497 – Calibration point -196 °C (nitrogen boiling point): €135
(additional nitrogen costs, see below) - kk-1496 – Calibration point -180 °C to -81 °C: €205
(additional nitrogen costs, see below)
3. Nitrogen Costs (Only for Low Temperatures)
For calibrations in a cryostat or at -196 °C, the use of liquid nitrogen is necessary. This is charged at a flat rate per calibration:
- kk-1477 – Nitrogen (50 l) for cryostat: €515 (for measurements in the range -180 °C to -81 °C)
- kk-1478 – Nitrogen (10 l) for -196 °C calibration: €105
4. Example Calculation
A typical industrial thermocouple could be calibrated at 5 calibration points
for example at:
- 0 °C, 100 °C, 300 °C, 600 °C, 1000 °C
The costs are then composed of:
- €150 basic costs (kk-1492 or kk-1493, depending on type)
- 5 × €110–135 per calibration point
For a selection of 3 calibration points (e.g., 0 °C, 100 °C, 600 °C), the net cost is approximately €555.
5. Volume Discounts
If several thermocouples are calibrated simultaneously at the same temperatures, we can offer attractive volume discounts:
- from 5 units: 15%
- from 10 units: 30%
Summary
The total cost of a calibration therefore depends on:
- the one-time basic costs (kk-1492 or kk-1493)
- the number and selection of calibration points (kk-1494 to kk-1497)
- if applicable, the nitrogen costs (kk-1477, kk-1478)
