The DMM4050 adds temperature and capacitance for greater versatility. See all digital multimeters »

Tektronix 4000 Series: 5½- and 6½-Digit Multimeters



Choice of 5½- or 6½-digit resolution Makes it unnecessary to pay for higher resolution than the application requires

True RMS (AC, AC + DC) measurements

Ensure high measurement integrity
2×4 ohms 4-wire measurement technique Allows performing 4-wire resistance measurements with excellent resolution and accuracy using only two leads instead of four.
Temperature and capacitance measurements (DMM4050) Provide a combination of measurements few DMMs can offer
TrendPlot™ paperless data recorder mode (DMM4040/4050) Plots the trend of a measured value over time graphically
Measurement statistics (DMM4040/4050) Calculates both the average and standard deviation of a measurement, as well as tracks the minimum and maximum measured values, with the push of a button
Histogram mode (DMM4040/4050) Displays the distribution of measurement results
Includes safety test leads, RS232 to USB adapter cable, and three year standard warranty Provides lower total cost
