Calibration

Calibration certificates for Tinytag data loggers, traceable to national standards, are available upon request. Prices can be found on this page.

Tinytag data loggers are guaranteed to meet the specification stated on their data sheets for a twelve month period from the point of sale. If required, additional calibration certificates traceable to national standards may be purchased. These calibration certificates can be provided at the time of purchase, and Tinytags already in use can also be returned for a service calibration at any time, for a standard charge.

Service Calibration

You can return your Tinytags for a service calibration at any time directly to Gemini Data Loggers. As well as issuing a calibration certificate, we also replace the unit's battery and any seals or desiccant packs (if present). If your data logger has a probe this must be returned with the logger for calibration. If calibration is required, we would suggest that loggers are typically checked annually. Critical or high accuracy applications may call for more regular checks however.

Please complete the Product Returns Form and return it with your loggers to the address below:

Calibration Department

Calibration (Time of Purchase)

If you would like to purchase additional calibration certificates when buying the loggers, remember to add the calibration cost for each one when placing the loggers in the basket. Our standard calibration points (above) for temperature and humidity data loggers are used unless otherwise specified.

Understanding Calibration

The calibration certificate provides verification that the data logger has been checked and has been found to be reading within the specification quoted on the unit's data sheet. Data loggers are compared to a reference meter that has been calibrated in a UKAS (United Kingdom Accreditation Service) approved laboratory. The certificate lists the value recorded by the reference meter (the temperature or humidity at which the data logger was tested), the value recorded by the data logger and the error between the two readings (the certificate will also show readings before and after any adjustment made to the unit where appropriate). In addition to the reading information, calibration certificates also list the test method and the details of the equipment used to provide traceability back to national standards.

Calibration certificates do not have a period of validity, they are simply a statement of what the unit was reading when it was tested.

Our standard calibration points are:

  • Temperature: 0 and 30°C
  • Humidity: 20 and 80 % RH (at 25°C)

These points have been chosen to give good coverage for general purpose use, but should other points be required we can calibrate units within the following ranges:

  • Temperature: -20 to +150 °C
  • Humidity: 20 to 90 % RH (at 25°C)

For CO2 loggers, our calibration points are:

  • 0 to 2000ppm units: 250, 500 and 1750ppm
  • 0 to 5000ppm units: 500, 2,500 and 4000ppm

For Energy Loggers, our calibration points cover a range of currents from 10 to 1,000A per-phase in both the single and three phase modes of operation. Voltage, power and power factor readings are also tested.

We do not have standard calibration points for voltage and current loggers. Please contact us to discuss the calibration points you require.
