Daiwa CN-901HP Meters offer accurate readings, reliable performance, and great value. Daiwa's large, lighted and easy-to-read cross needle meters will provide your ham shack with consistent readings. CN-901 Series meters feature qualities that will make measuring SWR and power during an antenna test, as well as matching and tuning transmitters, an easy task. Their dual-needle meters have one scale that measures forward power while the other reads reflected power. The existing SWR is indicated at the crossing point of the two needles… so you can read all three of these important measurements at the same time! Their HP models can also measure P.E.P. That's peak power in SSB operation. There are also several frequency-ranges and power levels in the Daiwa CN-901 professional series family to choose from.
