The two high-precision benchtop multimeters ST1951 and ST1961 conform to very high standards for measuring performance and measurement accuracy. The ST1951 has 119,000 count display and a DCV accuracy of down to 0.01 percent. Even higher measurement performance gives the ST1961 with 1,199,000 count display and a DCV accuracy of up to 0.0055 percent. In both devices, the bandwidth is up to 100 kHz and resolution up to 0.1 uV . The excellent measurement rate allows for up to 1000 measurements per second. They can be connected with external computers via a USB interface, the instruments and the calibration of the meter can also be achieved via an external interface.
A pair of test leads (black and red) is included with the delivery of the ST1951 and ST1961, as well as a connection cable, calibration certificate and instruction manual.
