The Lavatools Javelin PRO Duo has been radically designed with an ultra-large 2" display with 360° viewing clarity that automatically rotates depending on how the device is held. It's also the first food thermometer that has an intelligent stabilization alert which notifies you and holds the readout when it has settled.

Voted #1 mid-priced thermometer by America's Test Kitchen and Wirecutter.


The evolutionary next step of the Javelin line.
Blazing fast. No compromises.

Building on the success of the Javelin, our engineers have brought the response time of the Javelin PRO Duo down to a blistering 2-3 seconds by supercharging it with an ultra-sensitive Japanese sensor. And with an accuracy of ±0.9°F, it's performance is unrivaled.

Our brightest, sharpest display ever.

The key to the Javelin PRO Duo experience is through its large 2" backlit antifog display. We use a state-of-the-art display with a 360° global viewing angle, giving you spectacular clarity no matter how to look at it.
Our brightest, sharpest display ever.

Intelligence right at your fingertip.

Javelin PRO Duo's intelligent stabilization feature makes measuring temperatures even easier. By pressing the touch pad, the Javelin PRO Duo will hold the stabilized temperature and beep to notify you. Peering into the oven and guessing for readings has become a thing of the past.
Intelligence right at your fingertip.

A truly modern cooking thermometer.

Along with all the features found on the Javelin like integrated storage magnet, IP65 splash resistance, and silver-based antimicrobial protection, we built the Javelin PRO Duo to bring even more to the table.
