SWR/Watt Meter : NS-2104A

  This SWR/Watt meter is a highly accurate RF meter for measuring Forward Power, Reversed Power, Active PEP and VSWR by using cross-needle analog meter.
This wattmeter series offer many innovative features typically not found at this price level
DC Grounded Antenna connector prevents electrostatic buildup.
True Directional Coupler for increased accuracy over frequency.
Low Bias Schottky Diode Detectors for increased linearity.
Precision, 2.5” (64mm) Cross Needle Meter simultaneously displays forward and reflected power with SWR.
Individual Meter Scales for each power range increase reading accuracy.
Triple LED Backlighting provides smooth, even illumination.
Three Color Scale for improved readability.
LED Range Indicator.
High performance Active Peak Detectors* accurately captures a single “dit”.
Single knob Variable Peak Hold Time* for both Forward and Reflected axis.
Rugged metal cabinet with speckled black finish and designer style grey injection molded front panel aesthetically complements modern transceivers.
