- HIOKI RESISTANCE METER RM3548-50 [ NEW ]
High-precision Portable Resistance Meter Measures from µΩ to MΩ
The RM3548-50 is a precision handheld resistance meter measuring from 0.1 µΩ to 3.5 MΩ. It offers effortless operation and accuracy, making it ideal for EV maintenance, aircraft overhaul, and motor inspections.
RESISTANCE METER
Model:
RM3548-50
Maker:
HIOKI
User-friendly operation
Precision engineering
Adopts the four-wire measurement method and features an offset voltage compensation (OVC) function to ensure high accuracy measurements.
Simple resistance measurement
Enables even beginners to perform resistance measurements without the complexity of multi-functional devices.
Automatic calculations
Temperature correction converts the value of a resistance that depends on temperature, such as that of a copper wire, to a resistance value at a particular temperature to display it.
Wireless communication capability for even greater convenience
Easy! Just connect the optional Z3210 Wireless Adapter to your Hioki compatible instrument, to make it Bluetooth® ready.
Wirelessly connect Hioki-compliant instruments with a simple connection.
Transfer measurements to your smartphone or tablet and quickly create reports with field photos and drawings.
Direct Excel® integration
Boost work efficiency in the field by letting you directly transfer measurement data to (i.e., enter measured values directly into) templates created as Excel®.
The optional Wireless Adapter Z3210 is required.
Versatile probing options
Variety of probes to choose from
A diverse range of probes tailored to meet specific maintenance needs across various applications.
• L2140: Ideal for EV and hybrid car maintenance, the RM3548-50 excels in equipotential bonding tests, battery connection checks, and motor winding inspections. Compliant with UN ECE R100 standards, it offers dedicated probes, straightforward resistance measurements, and a PASS/FAIL function.
• L2141, L2142: Ideal for aircraft maintenance and overhaul, the RM3548-50 performs equipotential bonding tests to check resistance differences in various areas. The L2141 probe, with its rounded tip, is perfect for measuring resistance without damaging the aircraft body, while the L2142 probe’s sharp edge allows for resistance measurement through paint.
Optimized safety features
Circuit protection
In EV maintenance or battery busbar testing, accidental contact with live voltage can damage a resistance meter. The RM3548-50 features automatic overvoltage protection to prevent this, stopping measurements and safeguarding the circuit from live voltages of up to 60 V DC.
EV maintenance test tool
4 essential test tools for EV high-voltage shutdown and reinitialization
Recommended by leading EV and hybrid manufacturers for reliable and precise maintenance tasks, the RM3548-50 meets the UN ECE R100 international safety standards, which require a minimum measurement current of 0.2 A.
We provide reliable electrical test tools to ensure safe operations for EV maintenance and service personnel.
