Yokogawa WT110 Digital Power Meter

The Yokogawa WT110 Model 253401 is a Single Phase Digital Power Meter for Measuring Voltage, Current, Power, Power Factor, Frequency and Harmonics. This model is used principally for the measurement of power consumed by household appliances, such as air conditioners, automated office equipment, and other appliances, and they can be applied partially to the measurement of the output of invertor equipment. These meters are equipped with a rich array of functions: a comparator function, which is needed at production sites, and harmonic wave analysis, to which a lot of attention has been given. They can, therefore, be expected to be applied to a wide variety of services.

Features of the Yokogawa WT110 include:

• Large LED display
• Compact and lightweight
• Greater surge resistance Input component
