Oxygen Sensor Tester & Simulator

What kind of sensor can it be used with?

Zirconium, Titanium 1 Volt, Titanium 5 Volt , and also the popular dual cell wideband Oxygen sensors. Sensor can be heated or unheated (1, 2, 3 , 4 wires or 5 for wideband).

What it does?

A "lazy" or slow sensor is diagnosed with the simple push of a button which performs a response time test in a matter of seconds.
Wiring can be checked out by using the simulation functions and monitoring the engine response.
Signal output levels are displayed in real time on a fast response bar-graph..
Closed loop performance can be monitored by the cross counts of the signal shown in a large alpha-numeric display
Allows testing of the sensors on or off the vehicle.

Easy and safe to use:

Every function is activated by a single button, and the 300450 automatically detects and alerts the user of misconnections, overloads, etc.
Test leads are made of high temperature silicon insulation and high copper stranding conductor for maximum durability and flexibility.
For enhanced protection, the 300450 is equipped with a synthetic rubber holster, resistant to solvents, gasoline and other automotive chemicals.
Internal electronics not only safeguard the 300450 against overvoltages and currents, but also guard the sensors from being damaged in case of misconnections.
Test leads are equipped with wire piercing alligator connectors.
Only needs a 9 Volt battery, that lasts 25 hours of use or more.
Includes a complete and detailed user manual, which describes how to use the 300450, and also how to test Oxygen sensors and interpret the results.
