Testo® 400 - IAQ data logger for long-term measurements

The IAQ data logger is ideal for long-term measurements of indoor air quality. The measurement interval and duration of the stand-alone data logger are programmed using the testo 400 Universal Climatic Meter (please order separately). After completing the IAQ measurement, you can use the testo 400 to read out, analyze and document all stored values. Particularly practical: since the data logger acts independently of the measuring instrument during the measurement, you can use the climatic measuring instrument for measurements elsewhere in the meantime. Use the compatible probes (please order separately) to measure comfort, turbulence level, radiant heat, CO 2 , CO, illuminance, airflow, humidity and temperature. The IAQ data logger provides connectivity for up to six wired probes simultaneously. A convenient tripod can be ordered as an accessory for mounting the data logger and probes. Main applications of the IAQ data logger In conjunction with the appropriate probes, the IAQ data logger is ideally suited for the following measurements: PMV/PPD measurement according to EN ISO 7730 / ASHRAE 55 Local discomfort measurement according to EN ISO 7730 / ASHRAE 55 e.g. draft rate and turbulence level at up to three positions simultaneously NET measurement according to DIN 33403
