Measurement of air exchange rate

Air change measurement determines chamber air exchange according to ASTM D5374, including definition and protocol referenced to ambient temperature. The procedure characterises how quickly air is renewed inside temperature- or climate-controlled laboratory equipment under defined ambient conditions, supporting performance assessment of ventilation-related behaviour. Results are documented with a clear definition and measurement protocol aligned to the ambient temperature context specified for the test. Offered as 1 pc from manufacturer Binder, the item has a net weight of 0,5 kg and a gross weight of 1 kg and originates from Germany (Baden-Württemberg). Laboratories and validation groups apply this measurement when incubators, drying ovens, climate chambers or similar units require evidenced air-change data for qualification, monitoring or comparative evaluation. Linking the protocol to ambient temperature improves consistency of interpretation across test runs and sites. The ASTM D5374-based approach provides structured documentation suitable for quality systems, equipment files and audit packages where air exchange performance must be recorded alongside other chamber parameters.
