O2Alert Air/Fuel Recorder

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 additional 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).

• The Warning output can be used to activate warning light, enable fuel enrichment, shut down NOS or ignition, retard timing, etc.
• Recording can be started by preset RPM value or switch.
• Adjustable sample rates up to 100 samples per second.
• Custom configurations available. Call for info.
• Systems are upgradable.
• All recorded data can be played back on unit or downloaded and graphed on a PC. PC NOT REQUIRED!
