Description
The FNIRSI HRM-10 is a high-precision handheld battery internal resistance meter that uses the true four-wire Kelvin measurement method to simultaneously test a battery’s internal resistance and voltage — eliminating lead and contact resistance errors for highly accurate readings. With a voltage range of 0–100V DC and resistance range of 0–200Ω, it supports all common battery types including lithium-ion (18650, 21700), lead-acid, NiMH, car batteries, and power tool packs. For battery technicians, EV enthusiasts, solar system installers, and electronics repair shops across Karachi and Pakistan, the HRM-10 is an indispensable tool for assessing battery health, grading used cells, and building reliable battery packs.
Why Choose the FNIRSI HRM-10?
In Pakistan’s growing solar energy and UPS battery market — where knowing a battery’s true internal resistance is critical to pack reliability — the HRM-10’s Kelvin four-wire method delivers lab-grade accuracy at a fraction of the cost of professional battery analyzers. Its sorting mode, 8-cell batch view, historical data logging, and CSV export make it ideal for both individual cell graders and workshop technicians in Karachi who regularly test large numbers of batteries for solar backup systems, e-bikes, or lithium pack builds.
