TECMATE CarbMate™ — 12V, 2-channel, Black

This solid-state, two-input instrument displays the vacuum difference between two carburetors or throttle bodies on a single transverse 9-LED graph. 🔧

The bright color LED array removes visual estimation errors from comparing separate gauges by showing one clear readout that reacts quickly to even minor adjustments. ⚡

Accurate to 0.5 cmHg, it meets or exceeds OEM specifications and is shock resistant for durable field use. ✅

A central green LED indicates perfect balance within the selected resolution, while a zero-adjust knob enables quick pre-calibration with no hoses attached. 🔄

With an accessory (sold separately), the unit converts to monitor three or four carburetors/throttle bodies and serves as a cost-effective alternative to mercury sticks.
