Measure, analyze, and document all indoor air quality and comfort level parameters with this universal IAQ instrument. Additionally, this instrument comes equipped with a built-in measurement assistant which supplies optimum support for carrying out airflow and comfort level measurements in conformity with the standards.
Use this carrying case to store and protect your indoor air quality and comfort level measurement equipment. Additionally, it features compartments, which offers space for the appropriate measuring instrument, accessories, and probes.
Use the turbulence probe with the compatible 440 multifunction measuring instrument. Calculate the degree of turbulence and draft risk at the same time, in accordance with EN ISO 7730 / ASHRAE 55. The fixed cable is used to connect the turbulence probe to the 440 Air velocity and IAQ meter.
Use the lux probe with the compatible 440 multifunction measuring instrument. It assesses the illuminance according to the V-lambda curve, which corresponds to the sensitivity of the human eye in daylight. White or warm light LEDs K <5000 can also be measured without any problem.
Use the humidity/temperature probe with the compatible testo multifunction measuring instrument. Measurement Values are transmitted via Bluetooth, up to 65'. Thanks to a large measuring range of 0 to 100% RH and -4 to 158°F, you can measure relative humidity and air temperature reliably.
