Description

391B | Digital TRMS Handheld Multimeter, 40,000 Digits, Data Logging, 390B Series

The 390B series from B&K Precision includes high quality true RMS handheld digital multimeters specifically designed for accurate measurements in a wide range of applications. This series offers comprehensive measurement functions, including DC and AC voltage (DCV, ACV), DC and AC current (DCI, ACI), resistance, capacitance, frequency, diode test, temperature measurement and continuity testing.

The 390B series multimeters are ideal for technicians and engineers in areas such as electronics development, industrial maintenance, power supply and laboratory use. Thanks to their robust design with a dirt and water-resistant housing and a rubberized protective cover, they are also suitable for use in demanding environments.

Key features of the series:

  • True RMS AC and AC+DC measurements for precise results
  • Up to 100.000 counts on a dual display with analog bar graph
  • Automatic voltage detection (AutoV/LoZ) and high frequency rejection mode (HFR)
  • Bluetooth connectivity for wireless data logging (model 390B only)
  • Isolated USBinterface for remote monitoring and data logging
  • CAT III 1000 V / CAT IV 600 V protection for high safety

The Handheld Multimeter 391B presented here has similar specifications to the Model 390B. The main difference is the integrated Bluetooth connectivity that the 390B offers. The 391B offers a memory capacity for data logging of 20,0000 readings.
