FHS series Laser source are advanced version of DLS series Laser Source, with better features and more functions. Auto-Wavelength Recognition The FHS2D02 units can transmit with a wavelength-identification digital encrypted protocol,enabling the FHP2 Power Meter to automatically use the proper calibration parameters. This feature reduces the need for communication between the two technicians and decreases the potential for error. Easy-to-use, straight forward operation Eye-catching handheld package LCD backlight for easy operation in darker environments ±3dB Adjustable by the user. Rechargeable battery inside 850 & 1300 availale for multimode testing Three-year warranty and recommended calibration interval.
