The perfect tool for maintenance measurements of VRLA type batteries like UPS systems. Fast measurements, Bluetooth communication, pass/fail profiles and data export possibilities to excel help to make the life of service engineers easier and more efficient.

RM3548 is a high-precision, portable resistance meter capable of measuring resistance levels from microohms to megaohms. Ideal for portable measurements of winding and weld resistances in motors and stators for hybrid and electric vehicles, but also used to test the resistance of battery contacts in e-cars or rivet joints tests in the aircraft industry.

A 10 channel data logger for recording voltage, temperature, pulse or rotation signals, providing complete isolation between channels and strong noise resistance. It logs data at up to 100 samples per second (every 10ms) and allows data to be transferred via USB and stored on flash cards.

HIOKI's CM4003 leak clamp meter does not only cover 6 AC voltage ranges from 6mA to 200A but also features an analog voltage output for longer term recording of the current values. For this, a USB-C connector allows the unit to be powered by any USB power bank. Of course, Bluetooth communication with a smartphone or tablet is possible as well.
