All new dewpoint meters, hygrometers and inline moisture analysers manufactured by SHAW are supplied with a Calibration Certificate as standard. Dewpoint meter calibration accuracy is verified against our primary reference hygrometers, which are directly traceable to Humidity Standards at the National Physical Laboratory (NPL).

New instruments are delivered with a calibration certificate but this alone does not guarantee that they will provide good measurement throughout their operating life.

Incorrect operation, exposure to contaminants and corrosive gases, dewpoint sensor deterioration (ageing) and drift in electronics can all contribute to changes in the instrument accuracy over a period of time. It is therefore vital that a dewpoint meter, hygrometer and inline moisture analyser, is recalibrated at regular intervals in order to ensure that the process to which it is applied is measured and controlled correctly.

Shaw Moisture Meters Calibration Service for Dewpoint Meters

At Shaw Moisture Meters we offer full dewpoint calibration services in our environmentally controlled laboratory to ensure the constant accuracy of our dewpoint measurement equipment. This encompasses an overall calibration range of -110 °C to +20 °C (-166 °F to +68 °F) with the range -90 °C to 0 °C (-130 °F to +32 °F) dewpoint traceable to the Humidity Standard at the National Physical Laboratory via our absolute chilled mirror hygrometers.

Turnaround for dewpoint meter calibrations is typically five to seven working days. A detailed report will be emailed to you fully explaining the options and costs for any repairs. Please use the Equipment Return Form to enable us to deal with your dewpoint calibration or repair as quickly and efficiently as possible.
