Hewlett Packard 431B Power Meter

Got this vintage HP 431B Power Meter up for grabs. It's a classic piece of test gear for anyone into RF or microwave work. The analog scale looks great and the knobs all turn smoothly. It has the thermistor mount input on the front and settings for different resistance levels. I havent tested it with a sensor recently so selling it as is, but it powers on fine. Perfect for a lab setup or a collector of old school HP equipment.
