Product details:

Unique feature for precise measurement of voltage and frequency of motor drive with variable speed, in which harmonics superimpose the 87 V base frequency. Thanks to an integrated thermometer, you can easily measure temperature without having to take a separate 87 V thermometer. Optional magnetic hanger for easy setup and reading, while your hands remain free for other tasks. Display with large digits and bright stage background lighting ensures that the series 80 V measuring instruments are much simpler to read than the older models.
