Here is what the Coaxial website says about this meter:

The Model 81000-A Wattmeter ... now you can measure RF Power in 50-Ohm coaxial cable and transmission lines, and accept plug-in elements in the range of 100 mW to 10 kW full scale, and from 0.45 to 2300 MHz.

Complete with a built-in line section, our Quick Match RF connectors for 50-Ohm cables and transmission lines offer the speed and reliability you expect from Coaxial Dynamics.

The 81000-A is easy to use. Simply connect the Wattmeter between the power source and antenna or dummy load, plug in the appropriate measuring element and select forward or reflected direction. The RF power is directly displayed on the 4-1/2" triple scale meter.

Versatile and strong, the Model 81000-A can be used with accessory cables up to 200 feet from the meter and is protected by a rugged, virtually indestructible shock-proof housing. For added convenience, two sockets for storage of additional elements are located on the back of the unit.

The use of a rugged shock mounted meter with a mirror-backed scale along with superior taut band technology, provides reliable and accurate readings, and also satisfies both the US Navy and Canadian standards for bounce and vibration. This is your assurance of complete accuracy.
