2041 Portable Wattmeter
Brand: Yokogawa Electric CorporationModel 2041 Single-Phase Wattmeters and Singlephase Low-Power-Factor Wattmeters are electrodynamometer type wattmeters with indicators based on taut-band suspension.
It can handle DC and frequencies from 25 to 1,000 Hz, and provide excellent power factor characteristics.
These instruments are shielded with dual permalloy sheets as protection against external magnetic fields.
Features- Frequency Range: DC, 25 to 1,000 Hz (2041 01~03)
- Effective for Measurement of Low-Power-Factor Load Power and Small Power (2041 11~13, 21, 22)
- Low Self-Consuming Power
- Taut-Band Suspension System Eliminates Friction and Provides Strong Resistance to Shock Impact
