LX20 – Illuminance Meter – SANWA
Stick-shaped small light sensor (window diameter 9 mm) for narrow position or area
- Easy-to-carry pocket size.
- Separate, stick-shaped light sensor (window diameter 9 mm) from the main body enables measurement of a narrow position or area. The light sensor can also be integrated with the main body for measurement.
- 4039 full-scale count with a bar graph display.
- Improved measurement accuracy by using a silicon photodiode, which has a spectral sensitivity approximating the relative luminous efficiency specified by CIE (Commission Internationale d’Eclairage), in the light sensor.
- Wide measuring range of 0.1 lx to 403.9 klx (403,900 lx).
- Data hold function.
- Auto power save function prevents wasting of battery power.
