ETS offer an on-site calibration service, All equipment used by our engineers is UKAS calibrated. We are currently able to calibrate temperature, humidity, and vacuum. In order to verify the measurement accuracy of a climatic chamber, our calibration will be of the complete system, rather than the individual components.

In order to achieve this, we use monitoring sensors that are placed inside the chamber to record the environmental conditions existing either in the test envelope or at the control point. Our ISO 9001:2015 and ISO 17025:2017 Quality Management Systems ensure strict control of the documentation and procedures.

Equipment used for calibration:




A successful calibration service can contribute significantly to profitability by reducing waste, costs and time. Inadequately calibrated environmental test equipment may give incorrect information about tested products, and could lead to the belief that either bad products are passing the tests (potentially increasing warranty costs) or that good products are failing (which will incur unnecessary work as no fault is found).

In order for your environmental test equipment to perform repeatable accurate tests, they must be calibrated. ETS provides a calibration service for all makes of temperature and humidity chambers our aim at ETS is to perform reliable calibration results with guaranteed traceability. Our refined calibration procedures will give your equipment the most thorough and efficient instrument testing in today's market.

ETS can calibrate your chamber as a one off or it can be incorporated in a one of our service and maintenance packages. All calibrated chambers come with a comprehensive calibration certificate.

ETS can offer two types of calibration:

  1. Standard Calibration - traceable to national standards
  2. UKAS Calibration - completed by our UKAS accredited calibration laboratory No. 9735 which has met the requirements of international standard ISO17025:2017, and as accredited by the United Kingdom Accreditation Service (UKAS).

N.B: Calibration is a measurement against a calibrated instrument traceable to National Standards as found, it does not include adjustment. Adjustment involves re-calibration after adjustment.

ETS can also undertake altitude calibration (pressure), but ETS cannot offer a UKAS calibration for this measurement.

All ETS test equipment calibration is UKAS accredited.
