Testo 440 Lux Kit in detail
Testo 440 air velocity and IAQ measuring instrument:
- 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 monitoring: Enter the measurement time and measuring cycle to record data trends.
- Easy storage and evaluation of measurement data: Memory for up to 7,500 measurement protocols, readable via USB port as a CSV file (e.g., for Excel).
- Practical magnets for easy attachment of the measuring instrument to metal surfaces.
- Automatic detection of probes, such as the lux probe.
- Large, backlit colour display.
Lux probe:
- Use the lux probe to check the illuminance in offices, production areas, hospitals, museums, or schools.
- Measuring range: 0 to +100,000 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 issue.
- A 1.4 m fixed cable allows you to position the probe so that your shadow does not affect the measurement.
- Intelligent calibration concept: Only the lux probe needs to be sent for calibration, allowing the instrument to remain in use.
