Autometer Battery Tester 800 AMP w/ Unloader

AUTO METER Competition Instruments provides three types of gauges: advanced digital stepper motor, mechanical, and short sweep electric available at LMPerformance. The advanced digital stepper motor gauges by AUTO METER are powered by digitally controlled, rugged stepper motor drives and lab grade solid state sensors. These offer the extreme precision needed by the top racing teams worldwide. They offer the highest level of accuracy.

The AUTO METER mechanical gauges come with Bronze bourdon tube 270 degree sweep movements and durable nylon gearing. These gauges have been a favorite for 50 years. These mechanical gauges require no electrical power for operation making them an ideal choice for racing vehicles with no or low powered electrical systems.

The AUTO METER short sweep electric gauges have advanced 90 degree air core movements and simple three wire installation. Electric sending units keep hazardous fluids in the engine compartment sending collected data via an electrical signal to quick reacting, precise air core movements. This gives you all the information you need.

LMPerformance also carries AUTO METER shift lights. The Quick- Lite Shift- Lite has an Ultra-Fast response, vibration resistant Amber LED light. It is compatible with all external shift light tachometers and DPSS Controllers.

If you are thinking of an aftermarket performance gauge then you know you are buying from a company you can trust to provide you with a product that is second to none. Auto Meter is based right here in the United States in Sycamore, Illinois where they have a nonpareil cellular manufacturing plant, an inimitable engineering team, a sterling ISO 9000:TS 16949 Certified Quality System and technology that is unrivalled.

Here is some information on AutoMeter digital gauges and other products that you might find useful if you are considering an aftermarket performance guage:

If you are a drag racer you know you can get helpful surge of power at start with nitrous kit but if the pressure in it gets it too high you ride is going to run lean and conversely if the pressure is too low it will run rich. Install a nitrous pressure gauge from LMPERFORMANCE and you will be afforded the ability to monitor and maintain the correct pressure in your nitrous bottle.

We have been questioned about the possibility of using an Auto Meter shift light with an existing tachometer and the RPM Activated Module available at LMPERFORMANCE allows you to do just that even if you are using a factory tachometer or aftermarket tachometer that does not have shift light controls.
