Description

394B | TRMS Process Multimeter, 5 Digits

The 394B process multimeter from B&K Precision is a versatile measuring instrument that combines the functions of a mA loop calibrator with the capabilities of a true RMS digital multimeter. It has been specially developed for the requirements of process control systems and enables the measurement, simulation and output of 0-20 mA and 4-20 mA DC currents.

In addition, the device can be used as a high-quality general multimeter and offers functions for measuring voltage (DC/AC/AC+DC), current, resistance, frequency, continuity and diode test. The robust design with a water and dirt-resistant housing and rubberized protection makes it ideal for use in demanding environments, for example in industrial maintenance, process automation or electronics development.

Outstanding features of the 394B include:

  • True RMS AC and AC+DC measurements for precise results
  • 50.000-count display with dual display for parallel measurements
  • HART mode with integrated 250 Ω resistor for evaluating HART protocols
  • Integrated 24 V loop power supply, no external supply required
  • Ramp and step modes for automatic output current regulation
  • Optically isolated USB interface for remote monitoring and data logging
  • High Frequency Rejection (HFR) for precise AC measurements
  • CAT III 1000 V / CAT IV 600 V protection for safe measurements in high voltage environments
