The PM20CH Fiber Optic Power Meter is a robust, full-featured, handheld instrument, which together covers the full range of optical
fiber applications within the 800 - 1700 nm range with optical powers ranging from -50 dBm to +23 dBm (10 nW - 200 mW).
A rugged enclosure, internal sensor, and kickstand make this model ideal for field or lab applications.
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 PM20CH 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.
