Linshang LS123 Ultraviolet Power Meter
Portable UV irradiance and rejection measurement for glass and film demonstrations.
Product details
Measure UV performance
The LS123 measures UV irradiance in µW/cm² and compares unblocked and blocked readings to show rejection. A HOLD control retains the reading for inspection.
Select the correct instrument
Use consistent light-source and sample geometry for comparisons. The manufacturer specifies this model for low-intensity sources and glass or film demonstrations; it is not the instrument for industrial UV-curing or sterilisation-lamp measurement.
Manufacturer reference
