Testo 0577 0400 IAQ data logger for long time measurement

• Compatible with probes for measuring the comfort level, turbulence, radiant heat, CO2, CO, illuminance, air flow velocity, humidity and temperature
• Stand-alone data logger for long-term measurements up to 2 weeks
• Connect up to six fixed cable probes at the same time
• Data logger configurable via testo 400 universal IAQ instrument

The IAQ data logger is ideal for carrying out long-term measurements of indoor air quality. Programming of measuring interval and measurement period of the stand-alone data logger is carried out via the testo 400 universal IAQ instrument (please order separately). Once the IAQ measurement is completed, you can read out, analyze and document all the saved values with the testo 400.

Particularly useful: Since the data logger acts independently of the measuring instrument during the measurement, you can use the IAQ measuring instrument to carry out measurements elsewhere in the meantime.

Use the compatible probes (please order separately) to measure the comfort level, turbulence, radiant heat, CO2, CO, illuminance, air flow velocity, humidity and temperature. The IAQ data logger offers connection options for up to six fixed cable probes at the same time.

To install data loggers and probes, you can order an accessory in the form of a practical tripod.

Main applications of the IAQ data logger
In combination with the corresponding probes, the IAQ data logger is ideal for carrying out the following measurements:

• PMV/PPD measurement in accordance with EN ISO 7730 / ASHRAE 55
• Local discomfort level measurement in accordance with EN ISO 7730 / ASHRAE 55, e.g. draught rate and degree of turbulence at up to three positions at the same time
• NET measurement in accordance with DIN 33403
