W-20-TRMS Digital Voltmeter
digital voltmeter with RS-232 interface, software. The real effective value can be measured 

The W-20-TRMS digital voltmeter has an indicator with diverse symbols to show the different functions, as well as two warning symbols: one to show when the fuse is damaged and another one when the condenser is downloaded. In the digital voltmeter, cracks are indicated according to the selected measurement range. An alarm for errors and an acoustic signal are additional. This voltmeter will also determine capacitance, frequency and temperature. Our company also includes the software and the data cable in the delivery. There is another model of voltmeter with multiple functions, graphics, interface and software (multimeter, oscilloscope, logic analyzer ...) which can be seen here. Another similar voltmeter which is easier to use is the PCE-DM 22 Voltmeter. At this link you will find an overview of all the different voltmeters available from PCE-Group:I
