HIGH PRECISION METER: The fiber optic cable tester adopts high sensitivity with low errors of ±0.5dB to ensure the accuracy of values.
WIDE MEASURING RANGE: This fiber optical power meter measures from to 70dBm to 10dBm, which allows you to measure more optical devices conveniently.
WIDE WAVELENGTH RANGE: It supports 3 kinds of connectors and 7 wavelengths, including 850nm, 980nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm to make it suitable for different test environments.
MULTIPLE POWER UNITS: The tested power are shown with the forms of dB, dBm, mW, uW, nW. And there are 7 types to show wavelength. Long Standby Time: Three AA batteries (not included) power supply gives you super long standby time up to 48 hours, which makes it very reliable and practical.
ABSOLUTE POWER AND RELATIVE POWER: When wavelength is chosen, the screen will show the present value, including linear value of absolute light power and non linear value. When the wavelength is set in the mode of absolute light power, both absolute power and relative power will show.
