This battery and charging system monitor displays the condition of your battery and charging system instantly. It protects the engine computer and 12-volt accessories from damaging surges when jump starting or recharging. You can easily plug into the vehicle's cigarette lighter or power receptacle to monitor battery and charging system voltage. It has an LCD screen which displays the measured voltage with a bar graph to indicate battery charge level and it also has color-coded LEDs which quickly identify the battery's charge status. The head pivots for easy viewing and angle adjustment.

Measures the rotational speed with a visible red light beam from a powerful LED. It is a great tool to measure the RPM of motors and machine parts. In wood and metal working it can be used to accurately measure the speed of a lathe or milling machine. Can be used for HVAC applications in measuring fan speed. Detection distance up to 6 feet. Highly accurate, digital laser photo tachometer. To take the measurement, apply a reflective mark (included in package) onto the target object, aim the laser beam at the mark, the RPM displays on the LCD screen. Powered by 1 x 9V Battery (not included). Size : 180 x 72 x 37 mm(7.0 x 2.8 x 1.5 inch).

The HM011 is a self powered LCD hour meter, tachometer and maintenance meter. An internal lithium battery furnishes the power for the monitor. A wire around the spark plug wire of the engine provides both a tachometer signal an indicator that the engine is running. The maintenance meter is used to alert maintenance personnel that a time interval has expired and maintenance shuold be performed on the engine.

This electrical fuel level gauge gives high performance with a great racing look. It comes with a 2-in black face dial with white numbers and a red pointer that adds style and readability to its look. It has 12-volt internal lighting and is designed for negative ground systems. It includes gauge and mounting hardware and requires a fuel level sender.

Denso Air and Fuel Ratio sensor is designed to detect the amount of the exhaust gas air and fuel ratio. It is constructed from durable material that is corrosion and abrasion resistant. This sensor features zirconia solid electrolyte integrated with alumina heater substrate which precicely controls the amount of oxygen concentration that flows into the diffusion layer to limit current flow. This sensor can easily be installed and ensures longevity.

This fuel level sender is designed for use with an electrical fuel level gauge or deep tanks measuring from 5-in to 26-in. The sending unit has certain resistance specifications according to which, the range will be 240-ohms when the level is empty, the range will be 130-ohms when it is half full, and 33-ohms when totally full. The kit includes a gasket and mounting hardware but not thread adaptor fittings.

AEM's digital wideband air/fuel ratio gauges utilize a universal exhaust gas oxygen (UEGO) sensor to accurately monitor air/fuel ratios (AFR) during the tuning process. This gauge features a digital LED display and sweeping LED "needle" that changes colors as the air/fuel ratio changes from rich to lean. The unit's 52mm (2-1/16 inch) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere.
