FS/FT: Halmeter Air/Fuel meter
This is the most acurate meter for Air/Fuel there is
Essential to High Performance
An essential part of tuning any high performance engine is knowing whether the air fuel ratio is correct. A rich mixture will lead to a loss of power, while a lean mixture may result in detonation. The Halmeter AF30 provides a thirty LED readout of air fuel ratio, right there, in the cockpit, while you drive.
Exhaust Gas Analysis with the Halmeter
and the Lambda Oxygen Sensor
The design of the lambda or oxygen sensor provides a signal which is easily interpreted by the Halmeter AF30. The sensor produces a small voltage outout by comparing free oxygen in the exhaust gases with ambient oxygen outside the exhaust system. This voltage is created when the sensor is heated to between 360 degrees centigrade (680 F) and 900 degrees centigrade (1650 F) and varies between zero and one volt. The AF30 processes this voltage output and displays the result via a series of red, yellow and green LEDs: the red lights for lean, yellow for the stoichiometric band and green lights indicating mixtures likely to produce maximum power. It should be noted that, in the event the sensor is located in the exhaust where the temperatures are at or above the maximum, a reduced voltage output will result in fewer lights in the green band being lit at rich mixtures.
Dividing the small output from the sensor into thirty incremental LED's gives the Halmeter AF30 superior resolution compared to other instruments of its type.
The Halmeter AF30 Air/Fuel Ratio Indicator offers the tuner a low cost, attractive unit with thirty LED indicators that signal lean-optimum-rich.
The HalmeterAF30 Air/Fuel Ratio Indicator works on all engines, carbureted or injected, and with gasoline, alcohol or propane fuels. When used with programmable EFI systems, it helps establish fuel maps and makes the mixture trim control a more precise tool for on track tuning.
The Halmeter AF30 Air/Fuel Ratio Indicator kit is supplied complete with meter, wiring harness, oxygen sensor and exhaust fittings.
The Halmeter AF30/2 kit contains two oxygen sensors, with a special wiring loom and switch, to enable the user to monitor both sides of a dual exhaust system.
Dimensions
Height 1.875" 47.6 mm

Re: FS/FT: Halmeter Air/Fuel meter (quik2kSi)
i think this one actually wires into one of your o2 wires comming off the sensor. i know that it read really good when i took it out. hella more acurate than my autometer one
