Electrical

Monitors for Large-Cell Batteries

Install on lift trucks and other electric vehicles to display battery condition.

Battery Shunts

Connect these shunts to a battery and a panel meter or electrical testing device to measure the current flowing through a circuit when the current is too high to be measured directly by a meter.

Large-Cell Battery Surge Protector/Charge Monitors

See the charge level of a large-cell battery while protecting it from power surges. This monitor also checks the condition of your charging system.

Voltage and Conductivity
Testers for Large-Cell Batteries

Measure the voltage of your batteries as well as the current they can supply to check battery health.

Adjustable Battery Load Testers for Large-Cell Batteries

Test large engine batteries that draw up to 500 amps. Turn the dial to vary the load applied to the battery to see how it performs at different loads.

Battery Load Testers for Large-Cell Batteries

Apply a fixed load to small engine batteries that draw up to 125 amps.

Battery Load Testers with Alternator
Test Lead for Large-Cell Batteries

In addition to applying a fixed load to small engine batteries that draw up to 125 amps, this tester can check for defective alternator diodes.

Battery-Life Testers

Check if it's time to replace your disposable batteries.

Panel Monitors

See how much electricity motors, generators, and other electrical equipment use. The high-visibility digital screen displays electrical measurements with more accuracy than an analog panel monitor.

Analog Panel Monitors

Observe rapidly changing electrical values in equipment such as motors and generators with an analog display that shows the magnitude and rate of change more easily than a digital display.

Chemistry Testing

Battery Testing Density Meters

Check the condition of battery fluid by measuring its density to indicate the state of charge.

Concentration Meters

Also known as refractometers, these measure concentration with two or three drops of a solution.
