Calibration Laboratory
The GÜNTHER Group currently operates two accredited laboratories for the calibration of temperature sensors, as well as temperature display units and simulators. This not only creates redundancy for your calibration services but also enables us to consistently provide reliable results through a quality policy supported by internal laboratory comparisons. In our laboratories, we inspect and calibrate both sensors from our own production and measuring equipment provided by our customers.
Scope of Laboratory Activities
- Accredited calibrations (calibration certificates featuring the accreditation symbol)
- Non-accredited calibrations (factory calibration certificates)
- Functional testing and investigation of temperature sensor technology
- Consulting regarding calibratability and optimization of temperature sensors, as well as troubleshooting in temperature measurement chains
- Recommendations on the type and scope of required calibrations (e.g., for various heat treatment standards)
- On-site laboratory tours (e.g., as part of our customer training programs)
- Research projects in collaboration with our customers

The GÜNTHER Group’s Calibration Laboratories
The GÜNTHER Calibration Laboratory
The laboratory at the corporate headquarters in Schwaig, Germany, was commissioned as early as 1995 and has since been continuously expanded and equipped with the latest technology.
Recommendations on the Type and Scope of Required Calibrations
(e.g., for various heat treatment standards)
Depending on our customers’ field of activity, the requirements for the calibration of temperature sensors can vary significantly. By providing calibrations tailored to specific customer requirements, we not only help reduce costs but also prevent unnecessary discrepancies during audits.
With decades of experience and an extensive in-house library of standards compiled over many years, we offer our customers expert guidance in this area. Our goal is a precise analysis of each customer’s specific requirements. Once all necessary points have been clarified, we perform a calibration that is fully compliant with the relevant specifications.
Frequently Asked Questions Regarding Calibration Requirements
- What type of calibration is necessary or mandatory for a specific application? (With accreditation symbol vs. without accreditation symbol)
- How many calibration points must the sensor calibration include? (Is a single temperature point sufficient, or must a specific temperature range be covered?)
- What permissible tolerance or measurement uncertainty is required regarding the deviation of the temperature sensors?
- How many sensors must be calibrated in a multi-sensor delivery? (Is it sufficient to calibrate one sensor, should at least two sensors be calibrated, or is it mandatory to calibrate all sensors?)
