Bird 4412A Multipower RF Wattmeter with ±5% Reading Accuracy

Elevate Precision with the Multipower RF Wattmeter
The Model 4412A RF Wattmeter marries the iconic design and user-friendly interface of the Model 43 with advanced technology to offer a highly accurate, high dynamic range instrument for RF power measurement. This innovative meter features dual scales, 0 to 1 and 0 to 3, enabling precise readings across a wide range of power levels. It's designed for professionals who demand accuracy and versatility in their RF measurement tools.

Dynamic Range and Accuracy Combined
Power readings on the Model 4412A are determined by the value indicated by the pointer, with the decimal point location and multiplication factor depending on the range switch position and the plug-in element used. This wattmeter covers power ranges from 300 mW to 1 KW and 2 W to 10 KW full scale, ensuring broad applicability. With an accuracy of +/-5% above 20% of full scale for most elements, it stands as a benchmark for reliability in RF power measurement.

Designed for User Convenience
The Model 4412A is not just about precision; it's also built for ease of use. Its circuitry is powered by a rechargeable battery, ensuring that it's ready for use whenever and wherever needed. The inclusion of Quick Change (QC) connectors further enhances its user-friendliness, minimizing the need for adapters and simplifying the measurement process in critical applications.

Temperature-Compensated Measurements for Unmatched Reliability
This wattmeter is capable of temperature-compensated, accurate CW and FM power measurements from 200 kHz to 1 GHz and 300 mW to 10 KW. It utilizes special 4410-series wide-range elements to achieve wide-range accuracy over a 37 dB dynamic range, making it a versatile tool for a variety of RF measurement scenarios.
