Spartan 2 LB is a variant of our Spartan Lambda Controller 2 that is dedicated to Lean Burn applications. Spartan 2 LB reads oxygen concentration from 0[%] to 21[%] with a resolution of 0.1%. Spartan 2 LB is suitable for a wide variety of applications such as Lean Burn engine tuning, power generation, wood/coal/gas burners, and much more.

Spartan 2 LB is the first Wideband Oxygen Controller to use all extended temperature components, this means Spartan LB 2 offers the widest operating temperature; -40[C] to 125[C], of any Wideband Oxygen Controller on the market. From the frozen Arctic Tundra to the baking heat of Death Valley, Spartan 2 is the Wideband Oxygen Controller you can rely on.

Spartan 2 LB is the first Wideband Oxygen Controller to use all automotive grade components, it is the same quality components OEMs use for mission critical electronic systems. Automotive qualified components offer increased reliability, increased resistance to electromagnetic interference, and exceptional durability when compared to non-automotive grade components.  

The advanced design, high quality components, and extensive factory calibration means  0.1% O2 concentration accuracy — without the need for any calibration.

14Point7 stands behind this product with a warranty that is twice as long as any competing product. With an unrivaled 60 day money back guarantee, you can buy with confidence and know that you are getting the absolute best.
