DynamicConductance Technology
Breakthrough battery testing
technology from Midtronics
delivers improved battery testing
accuracy and decisiveness.

Direct Temperature Measurement
Creates a third dimension to the
Midtronics battery test algorithms,
improving decisiveness and making
all decisions more accurate.

Deep Scan Testing
Uses multiple frequencies and test
points on deeply discharged batteries to
make more decisions so that customers
can avoid charging batteries with shorts,
opens, and bad cells.


More functions and expandability
From battery, starter, and alternator diagnostics to circuit integrity testing, the EXP is the most versatile and reliable electrical diagnostic tool on the market
today. With the ability to perform more tests with one tool, you can be more efficient, cut costs, and easily update to the newest technologies.


Enhanced Starter Diagnostics
Using the optional Amp Clamp provides an enhanced
level of diagnostics beyond just starter voltage drop.
The EXP starter diagnostics include starter amps draw,
voltage drop, start time, and starter circuit resistance
resulting in more accurate results.

Digital Signal Processing (DSP) Capability
For Advanced Alternator Diagnostics the EXP uses superior DSP capability to digitize the measured alternator output
voltage and evaluate the spectral content of the signal.
This digitized signal allows the EXP to combine pattern recognition with the amplitude level of the AC signal for
improved accuracy and identification of open or shorted diodes and open phase conditions, (multiple diode failure
or winding problems).

Midtronics GRX-3000 Battery Diagnostic Station

Easy-to-use scalable solution designed to support full-service battery management programs

Fast, accurate and reliable, the GRX can determine, often in less than five minutes, the difference between a recoverable battery and one that is not. Diagnostic charging is uniquely designed to continuously monitor the charging progression. Each session is customized and highly controlled charging stops as soon as a battery can be returned to the customer or is determined to require replacement. Defective batteries with open welds and shorts are identified rapidly and recoverable batteries are quickly and safely charged, putting your customers back on the road faster. The GRX diagnostic station delivers better efficiency in the shop, clearer test results and more accurate preventative maintenance decisions by helping to eliminate guesswork and wasted time charging defective batteries. Available in the Americas (110 volt)
