- B&K Precision offers the 390B series of portable digital multimeters with Bluetooth connectivity, enabling measured values to be transferred to a smartphone or tablet.
This family of multimeters, with a CAT III 1000 V / CAT IV 600 V protection rating, comprises four models equipped with backlit displays, various test and measurement functions (voltage, current, resistance, frequency, continuity, dB, diode test, etc.) and data logging capabilities (20,000 or 40,000 readings).
These field instruments feature a dual display of 400,000 or 100,000 points, depending on the model. Their DC voltage measurement accuracy is 0.03% or 0.015%.
Automatic display backlighting adjusts for better visibility in low-light environments, while optimizing battery life.
These portable multimeters feature Bluetooth connectivity for wireless transmission of measurements and data logging from a mobile device running Android/iOS.
They are equipped with process calibrator functions, including a 24 V loop power supply and a 250 Ω HART® resistor. This enables measurement, generation and simulation of standard control loops from 0 mA to 20 mA and 4 mA to 20 mA.
These portable instruments can also be connected to a PC via their built-in isolated USB interface. Measurement data recorded in the field can be exported to a PC using the operating software supplied with the instrument.
