Description:
Qialan provides high precision optical multimeter. QLM2 Series Optical Multimeter integrates a stable optical laser source and a precise optical power meter.
The optical laser source unit launches the laser whose wavelengths are at 1310/1490/1550nm or 1310/1550nm (according to the model). The optical power meter unit can recognize the wavelength automatically.
QLM2 Series Optical Multimeter offers a large storage capacity; With the assorted software, user can generate a report or manage the test report easily.
Features:
- Auto wavelength recognition
- Data storage up to 999 items
- USB interface and PC associated software available
