[PD-350 range] TRMS AC/DC multimeter (1000V / 20A) with voice and datalogger

CATIII RMS digital multimeters with Bluetooth connection to mobile phones (smartphones) and tablets for remote control and datalogging. Voltage, current, resistance, capacity, frequency, diode, transistors, continuity and temperature measurements.

True RMS, Bluetooth... or both?
  • PD-350: True RMS measurements
  • PD-351: Voice + Datalogger (Bluetooth connectivity)
  • PD-352: True RMS and Voice + Datalogger (Bluetooth connectivity)

The PROMAX PD-350 digital multimeter range offers a new way to perform measures. The PD-35x are more comfortable, more accurate and with additional features (TRMS, Bluetooth connectivity) that turns them into very suitable instruments not only for daily work but also for training centres, universities and electronic enthusiasts.

The True RMS measurements ensures precise readings in alternating current. The Bluetooth connectivity allows to use the instruments from any compatible Android device and to use the voice synthesis to listen the measurements, to remotely control the instrument, to display a measurement graph and to store the measurements in CSV format to later process them in a datasheet.

PROMAX PD-352 is a TRMS (True RMS) multimeter that in addition to the classical Voltage, Current, Impedance, Frequency and Capacity included in most digital multimeters also included the Duty Cycle measurement, Temperature, Diode Test, Continuity test, Data hold, Max/Min hold, Relative measurement and a wide backlighted screen with a 61-segment bar graph together to the numerical measurements.
