Linshang LS122 Infrared Power Meter
Portable infrared irradiance and rejection measurement for glass and film demonstrations.
Product details
Measure infrared intensity and rejection
The LS122 measures irradiance in W/m² and calculates rejection by comparing readings before and after inserting a sample. The HOLD control freezes a result for reading or demonstration.
Understand the measurement
Its 1,000–1,700 nm response differs from a transmission meter using one infrared wavelength. Keep source, sensor and sample geometry consistent when comparing readings. This instrument reports infrared performance within its response band, not total solar-energy rejection.
