Measurement Parameters

To ensure the quality of your measurements, data logging systems should be re-calibrated periodically. Our qualified calibration specialists are trained to perform all required tasks on all ELPRO data logger systems for many different measurement parameters.

In many industries and applications, reliable temperature measurements are critical to process stability and quality documentation. ELPRO calibrates your temperature instrumentation equipment using

  • high-end equipment like calibration baths or dry-block calibrators to simulate temperatures,
  • physically fixed points like 0 °C (ice / water) or -196 °C (liquid nitrogen),
  • high-precision reference instruments.

Calibration range:

  • -196 °C
  • -90 °C..+150 °C

Relative Humidity
Relative humidity calibrations are performed using:

  • Humidity generators equipped with reference instruments or dew point sensors
  • Humidity standards based on saturated salt solutions

Calibration range:

  • 0.5% RH..95% RH

Pressure Differential
Pressure differential instruments are calibrated using precision equipment consisting of pressure generators and high-end reference instruments.

Calibration range:

  • -199 Pa..+199 Pa

Having correct levels of CO2 concentration is vital for many processes in the life science industry. To make sure you can trust your readings, ELPRO is calibrating the CO2 sensors using reference gases with different concentrations.

Calibration range:

  • 0 %
  • 5 %
  • 10 %
  • 20 %

For your airborne particle counters, ELPRO can perform 0 particle and comparison measurements and check the flow rate.


The quality of our calibrations is important to us; therefore, all calibrations are performed in accordance with DIN EN ISO 17025 for highest quality standards. And, of course, the calibration and validation certificates issued by ELPRO are traceable to national and international standards.

SCS (Swiss Calibration Standard)
The ELPRO head office in Switzerland is an officially accredited calibration laboratory for temperature and humidity. You can download the SCS Accreditation Certificate here.

ELPRO Services, Inc. in Marietta, OH is an accredited calibration laboratory for temperature. You can download the ANAB Accreditation and Scope Certificate here.


ILAC – The International Laboratory Accreditation Cooperation - is an international cooperation of laboratory and inspection accreditation bodies. Each accreditation body used by ELPRO to certify calibration activities (SAS, NIST) is a full member of ILAC, guaranteeing international traceability and validity of the certificates issued by ELPRO.


Off-Site Calibration
Calibration can be performed in one of our state-of-the-art calibration labs:

  • Switzerland: ELPRO-BUCHS AG
  • Germany: ELPRO Messtechnik GmbH
  • USA: ELPRO Services Inc.

We look forward to calibrating your equipment in one of the laboratories listed above.

On-Site Calibration
To ensure that your data logging system is removed from your process only for the shortest time possible, ELPRO offers on-site calibration services. Due to our experience and expertise in such field calibrations, we can reliably and precisely calibrate your valuable instrumentation directly at your site. Please contact your local ELPRO partner to find out more about this convenient service offering.



The ELPRO Thermal Mapping Service is a simple, efficient way to obtain a GMP-compliant mapping report. No need to buy data loggers, no special software, and a minimum of time and resources. Regardless of your location, we don‘t need access to your site and no one needs to travel.

You provide us with a floor plan of your facility. Based on facility size and layout, our experienced thermal mapping specialists determine the location and number of measuring points. The data loggers are mailed to you with instructions for placement and activation. Your staff places the data loggers according to the map and presses the TRANSIT button. At the end end of the mapping period, simply collect the loggers and e-mail the PDF reports to ELPRO for final report generation.

This eliminates the need to dedicate valuable time and resources to mapping and report compilation.


The reports created by ELPRO include a summary, graphs for each measuring point and of course calibration data for each instrument used during the mapping exercise.


ELPRO uses the proven LIBERO PDF Logger for measuring and collecting the data during qualification studies. Given its high accuracy of ±0.2 °C and the instrument's capability of generating a PDF report without the use of any software make the LIBERO the ideal instrument for mapping exercises.
Where humidity needs to be mapped, ELPRO uses the LIBERO THi1, relying on proven sensor technology and convenient handling.
Of course, all data loggers used during mapping studies are calibrated and come with a calibration certificate which is traceable to national and international standards.
