-50 dBm to 23 dBm (10 nW - 200 mW) for PM20CH
Interchangeable Fiber Connector, FC Adapter Included (SC, ST, LC, or SMA Adapters Can be Ordered Serperately)
Absolute and Relative Measurements Displayed in W, dBm, dB
NIST-Traceable Wavelength Calibration in 5 nm Steps
50 Hours of Operation Between Charges:
The PM20 Series of Fiber Optic Power Meters are robust, full-featured, handheld instruments, which together cover the full range of optical fiber applications within the 400 - 1700 nm range with optical powers ranging from -60 dBm to +23 dBm (1 nW - 200 mW). A rugged enclosure, internal sensors, and kickstand make these models ideal for field or lab applications.
Functionality
Efficient, low-power circuitry provides long battery operation. The alphanumeric 8-digit LCD display allows easy power read-outs. The operation of the device is intuitive due to the clearly labeled key pad. All common features like wavelength setting, relative measurements, power read-out, and auto-shutdown are included. The PM20 is powered by a built-in rechargeable NiMH battery or by the included AC adapter that also recharges the battery. The unit comes with an FC fiber adapter. Most industry standard fiber adapters (i.e. SMA, SC, ST, FC, and LC) are available for purchase and can be easily installed.
