Designed to measure both the absolute optical power and relative power loss in fiber optic cables. These power meters feature the following:

• Measures a wide variety of wavelengths from 800-1650 nm, with a mere 0.01 dB resolution
• Measures 6 preset calibrated wavelengths with high precision to determine absolute or relative power
• Special function of the unit allows the device to be manually calibrated as needed
• LED screen is backlit for viewing in low light locations and a 10 minute auto-off helps preserve battery life
• Dust-proof button design and shatter-resistant sleeve protect the tool to last a lifetime
• Recommended for use with FLS-50 or FLS-55
• FPM-50A, FPM-55 & FPM-70include: Fiber Optic Power Meter, Instruction Manual, Protective Cover, (3) AA Batteries (required for operation), (2) Cleaning Swabs, FC Adapter, LC Adapter, SC Adapter and a Nylon Carry Case.
• FPM-55includes data storage
