This element is for use in:
Bird Model 4410A Multi-Range Broadband Wattmeter (Not Included)
Multipower and High Accuracy ±5% Reading

The Model 4410A Wattmeter uses the basic principles and “look and feel” of the Model 43 but transforms it into a highly accurate high dynamic range instrument. The mirrored-scale linear range meter has 2 switchable ranges, 0-1 and 0-3. Power is read as a multiple of the value indicated by the pointer, the decimal point location depending upon the range switch position and the factor printed on the plug-in element. Power ranges covered by individual optional elements are 2 mW to 10 W, 20 mW to 100 W, 200 mW to 1 KW and 2 W to 10 KW, full scale. For most elements, accuracy is +/-5% anywhere above 20% of full scale. The circuitry operates from a standard 9V alkaline battery. 

This sale is for one element only, a Wattmeter is not included.
