Fiber optic power meter
Fiber optic power meter with built-in probe
The PM20 series fiber optic power meter is a stable and comprehensive handheld optical power meter. Their application range covers the entire fiber optic application range within the wavelength range of 400 nanometers to 1700 nanometers, with optical power ranging from -60dBm to+23dBm (1 nanowatt to 200 milliwatts). The sturdy casing, internal sensors, and support frame make it an ideal choice for laboratory applications.
Function:
High efficiency and low-power circuits result in longer battery life. The 8-digit LCD display can directly read the results. Due to clear label instructions on each button, the operation of this device is very intuitive. It has all commonly used functions, such as wavelength setting, relative measurement, power readout, automatic shutdown, etc.PM20The fiber optic power meter is powered by a built-in rechargeable NiMH battery or by an accompanying AC adapter that can also recharge the battery repeatedly. The device also comes with an FC fiber optic adapter, which is compatible with FC/PC and FC/APC connectors.
The power meter compatibility table provides an overview of our complete optical and laser power meter products, including probe and compatibility information. Each header is equipped with the following components: header with built-in probe, FC fiber optic adapter, 12V DC power supply (PMPS12), calibration table, and operation manual.
