Palm-sized Optical Power Meter

The palm-sized CSM1 optical power meter accurately measures optical power in Premises, Telco, or Broadband fiber optic networks.  Weighing only 0.4 lb, this power meter is ideal for field use.

The CSM1 stores optical references for each calibrated wavelength and features multiple test Tone detection for fiber identification. A large LCD display with backlight shows measured power [dBm or µW] or insertion loss [dB], calibrated wavelengths [nm], tone frequency [Hz], and indicates a low battery condition.

The CSM1 optical input port accepts a variety of NOYES thread-on style adapter caps (ordered separately) to meet a wide range of testing requirements. One adapter cap, 2.5 mm Universal, is included. 

Powered by two AA alkaline batteries, the CSM1 offers a five-minute auto-off feature and over 300 hours of operation with backlight off. 

The CSM1 is fully N.I.S.T. traceable.
