Brief description:

 

TH1912 is 4 1/2 double VFD digit AC millvoltmeters, which can also be used as power meter and level meter.

 

The test value and operation value can be displayed. The adoption of intelligent micro processor control technology, good amplifier and A/D linearity cymoscope makes the deviation of test voltage lower than 1%.

 

Chip production and installing craft make the millivoltemeter with the good performance of small volume, light, high stability, fast test speed, small deviation of frequency response .etc Setting function of multi parameter and math operation, as well asthe function of ground and float, expands the using range of millivoltemeter, and improves the safety.

 

Standard RS 232 interface, optional GPIB interface, and general RS232 software are provided to meet the demand of connecting with computer and forming auto test system. The instrument can receive the SCPI command to guarantee the compatibility of communication software.
