Relative Humidity

Our Service in the calibration laboratory for Relative Humidity / Air Temperature

Based on our long-time experiences we offer accredited calibration services for the measuring quantity relative humidity / air temperature according to ISO/IEC 17025 with DAkkS calibration certificate.

Our range of services includes the calibration of:

Sensors and measuring instruments, like

  • Dew point mirrors
  • Sensors for relative humidity
  • Sensors for air temperature
  • Data loggers with internal or external temperature- / humidity sensors
  • Thermo hygrometers
  • Weather stations

In our two-pressure-two-temperature-humidity generator we calibrate your instruments with lowest uncertainties according to the primary method in the following calibration range:

Dew point: -20 °C to 70 °C
Relative humidity: 5 % to 95 %
(Temperature range from 5 °C to 70 °C)
Air temperature: 5 °C to 70 °C

In our climatic chambers we calibrate your instruments by comparison method with a reference dew point mirror in the calibration range:

Dew point: -20 °C to 90 °C
Relative humidity: 5 % to 95 %
(Temperature range from 5 °C to 95 °C)
Air temperature: -70 °C to 180 °C

Climatic chambers / ovens

Climatic chambers / ovens according to DKD-R 5-7
Relative humidity: 5 % to 95 % bei 5 °C to 95 °C
Temperature: -80 °C to 500 °C (without air circulation up to 350 °C)
Calibration of climatic chambers according to method A of DKD-R 5-7 up to a size of 80 m3

 

Our complete range of calibration services, including expanded measuring uncertainties, can be found in the Annex to accreditation certificate (D-K-15186-01-00).

We provide:

  • Calibration of your measuring equipment for relative humidity with lowest uncertainties
  • Calibration points according to customer request
    or standard calibration (30 / 50 / 70) % at 23 °C

 

On-site calibration

Your measuring equipment is permanently in use and the delivery to a calibration laboratory is not possible due to technical or temporal reasons?

Our experienced on-site team comes directly to your place. In this way, you save yourself unnecessarily long downtimes and have a competent contact person directly on site.

We also calibrate your temperature measurement equipment directly on-site in your workspaces and facilities, depending on the technical requirements, according to accredited calibration procedures (DAkkS).

Calibration of Climatic chambers according to DKD-R 5-7

  • in the range from -80 °C to 500 °C (without air circulation up to 350 °C)

Calibration of climatic chambers according to method A of DKD-R 5-7 up to a size of 80 m3

 

Calibration of your humidity measuring equipment in a two-pressure generator

  • Data loggers with cubic dimensions
    Max. dimensions of (10 x 85 x 40) mm or (95 x 95 x 40) mm
    (10 to 90) % relative humidity at approx. 25 °C
  • Rod sensors with plastic shaft
    (10 to 90) % relative humidity at approx. 25 °C
  • Air temperature sensors at approx. 25°C
  • In dependency from the technical preconditions

 

Calibration of your humidity measuring equipment in the process environment

We calibrate your hygrometers in the process environment at the installation site, presumed that the process environment meets the requirements for a climatic chamber according to DKD-R 5-7.

 

Determination of temperature stability and homogeneity in cold rooms and store rooms

The storage of various raw materials and products often places high demands on the ambient temperature.
With our standard equipment we determine the temperature distribution and stability in your storage rooms, e.g. over a period of 24 hours, and provide you with a detailed test report with graphical evaluation.
