The Ando AQ2150 Optical Multimeter is a modular, handheld instrument for optical power and wavelength measurements in field and laboratory environments. Its interchangeable sensor, light source, and return loss units enable operation as an optical power meter, stabilized light source, loss test set, or return loss measurement system. Weighing approximately 450 g, the instrument operates on AA batteries, AC adapter, or optional Ni-Cd battery pack, eliminating external power dependencies for portable field work.
