Keithley 2100 6½-digit USB Digital Multimeter

The 2100 6½-digit USB digital multimeter offers the combination of high performance and accuracy (38 ppm) appropriate for making critical measurements. It has 0.0038% 1-year basic DC voltage accuracy on the 10V range and 0.013% 1-year basic resistance accuracy on the 10kΩ range. At 6½ digits the 2100 delivers 50 triggered readings per second via the USB remote interface. At the fast 4½ digit setting, the 2001 reads more than 2000 readings per second into its 2000 reading internal buffer.;The 2100 is rugged comes with removable rubber bumpers and a sturdy handle making it durable and portable for use in various ranges of test settings. The low cost and high precision makes this instrument ideal for R and D engineers, scientists and students and can be used as a bench top digital multimeter or in a system application.;The 2100 is quick to set up and also easy to use, due to its high contrast front panel and keypad. Each function can be distinguished by its colour.
