Sanwa Electric Instrument Co., Ltd.
Sanwa LX20 Environmental Meters
Manufacturer: Sanwa Electric Instrument Co., Ltd
Model: LX20
Features
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.
