lightmeter

Small size luxmeter that can be used in working environmental check, illumination design verification and other light monitoring applications. If the user turns on this unit with the cap on, it will zero the reading automatically. With the sensor on the top of the tester, this meter can easily operate with single hand. The sensor is compensated with filter to make the response close to human eye. The light source angle is also compensated according to its cosine function. 

Key features:

  • 5 Digital display;

  • Auto ranging;

  • Automatic power off;

  • Fc / lf function selectable;

  • HOLD function;

  • Range display;

  • Automatic zero when power on

  • Range: 0 - 40.000 lx (0 - 4.000 fc)

PHOTO-RADIOMETER

Portable instrument with a large LCD display.

It measures illuminance, luminance, PAR and irradiance (across VIS-NIR, UVA, UVB and UVC spectral regions or measurement of irradiance effective according to the UV action curve). 

The probes (must be ordered separately) are fitted with the SICRAM automatic detection module: in addition to detection, the unit of measurement selection is also automatic. The factory calibration settings are already memorized inside the instruments. 

The Max, Min and Avg function calculate the maximum, minimum or average values. 

Other functions include: the relative measurement REL, the HOLD function, and the automatic turning off that can also be disabled. 

The instruments have IP67 protection degree.

Measuring unit lux - fcd - μmol/m2.s - cd/m2 - W/m2 - μW/cm2
