Opt for the kit that includes the testo 440 air velocity and IAQ measuring instrument and lux probe for measuring the illuminance in workplaces.
testo 440 Lux Kit in detail
testo 440 air velocity and IAQ measuring instrument:
-
No task is too challenging, no application too specialized: the testo 440 combines a compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes -
Clearly structured measurement menu for long-term measurement: for long-term monitoring, enter the measurement time and measuring cycle in the measuring instrument and record measurement data trends -
Easy storage and evaluation of measurement data. Measurement data memory for up to 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on the computer (e.g. with Excel) -
Practical magnets for easy attachment of the measuring instrument to metal surfaces -
Automatic detection of probes, e.g. lux probe -
Large, backlit colour display
Lux probe:
-
Use the lux probe to check the illuminance in offices and production areas, hospitals, museums or schools -
Measuring range: 0 to +100000 lux -
Standard-compliant: accuracy according to DIN EN 13032-1 and class C according to DIN 5032-7 -
Suitable for all common lamps and light sources: assessment according to the V-lambda curve -
White or warm light LEDs (K< 5000) can be measured without any problem -
Use the fixed cable to connect the lux probe to the testo 440 air velocity and IAQ measuring instrument. Thanks to the 1.4 m cable, you can position the probe in such a way that the measurement is not affected by your shadow -
Intelligent calibration concept: the air velocity and IAQ measuring instrument remains in continuous use, since only the lux probe needs to be sent in for calibration
