19# 2-In-1 Fiber Optical Light Source Optical Power Meter

Features:
- Advanced two-color integrated mold process for extra durability; Top dustproof over protects the fiber output connector
- Multiple Optical Wavelength Outputs: Single port with two wavelengths; Dual port with 4 wavelengths (two single modes, two multi-modes)
- Modulation Function in 270Hz, 1KHz, and 2KHz
- Adjustable Output Optical Power: adjustment range is 6dB, stepping 1dB
- Universal Micro-USB Interface: Support multiple power supplies such as charger adapter, power bank, and PC tablet, featuring long working hours
- Smart Switchable Power Supplies: Priority to using power adapter, followed by built-in rechargeable batteries, and then dry batteries (Batteries are not included). When the electricity of rechargeable batteries is too low, it will switch to the mode powered by dry batteries. When the former one is recovered, then it will switch back again. There is no need the turn the meter off, working as normal.
- Automatic shutdown function to save power
- Support various removable optical output connectors
