Testo 440 Lux probe for measuring light intensity

Part Number:0635 0551
ships in 2 to 3 weeks
Use the lux probe with the compatible testo 440 multifunction measuring instrument (sold separately) to determine illuminance. The lux probe is ideal for determining the illuminance in workplaces. 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< 5,000) can also be measured without any problem. 
The 4.6 Ft. cable length means that you can place the probe directly at the measuring location and carry out the measurement from a sufficient distance, ensuring that the readings are not affected by your shadow. The clearly structured measurement menu for long-term measurement enables the measuring instrument to be operated intuitively. 
Reading trends are reliably recorded thanks to the convenient input of measurement time and measuring cycle. 
 Intuitive: clearly structured measurement menus for multiple applications 
Precise: calculations are performed automatically inside the testo 440 application screens Convenient: Universal connection handle can be easily combined with other probe heads
Intelligent calibration concept. Only the probe tip needs to be sent for calibration.
