The O2alert is the first data recording system specifically designed to record Air/Fuel Ratios with a warning output! Not only does it record up to 2 Wideband Oxygen sensors but it also records engine RPM , battery voltage, and has a programmable Warning output to protect against "lean-out".
Unit is housed in a durable aluminum extrusion with backlit display and is only 4"x3.25"x1.25".
Standard System comes with 1 wideband sensor, engine RPM (does NOT require additional rpm module as with other systems), Battery Voltage, Warning output, and software.
System has options for 1 additonal built in wideband oxygen sensor, plus (EGT) thermocouple, plus 2 analog channels (RPM, pressure, flow, position, external wideband (see our part # ALT-OWBC), etc..., or A/F voltage output).
