- Measures illuminance according to V-lambda curve
- Suitable for all common light sources
- Standard-compliant accuracy according to DIN EN 13032-1 and class C according to DIN 5032-7
- Non-slip contact surface ensures firm positioning at measuring site
- Fixed cable on handle easily connects probe to measuring instrument
- Intelligent calibration concept allows main unit to be used continuously, with only the probe requiring calibration
The Testo 0635 0551 Digital 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< 5000) can also be measured without any problem.
The 4.6 ft. fixed cable on the handle is used to connect the Lux probe to a measuring instrument (sold separately). The long cable length allows you to place the probe directly at the measuring location and carry out the measurement from a sufficient distance - readings therefore 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.
Intelligent Calibration Concept
Users receive exceptionally accurate measurement results with the digital probe, because the measuring instrument makes measurement uncertainty a thing of the past. Only the probe needs to be sent in for calibration - allowing the measuring instrument to remain in continuous use.
Areas of Application for the Lux Probe
Light conditions serve an important role in workplaces. In order for light to also be good light, the illuminance must meet certain minimum values. Use the lux probe to check the illuminance in offices and production areas, hospitals, museums or schools with reliability.
