Manufacturer’s description:

The DWM-2104A is an active peak reading wattmeter with simultaneously variable hold time on both the forward and reflected meter movements. This variable delay can be adjusted for quick action for high speed CW, or for longer periods more appropriate for the display of SSB and AM voice peaks. The peak detectors sport a new fast attack design capable of capturing quick pulses such as a single dit.  LED meter illumination.

    DC Grounded Antenna connector prevents electrostatic buildup on your antenna.
    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. 20W / 200W / 2000W range with LED Range Indicator.
    High performance Active Peak Detectors  accurately captures a single “dit”.
