cln_img_9724Thew new Mk4 features intelligent backlighting.  A version of backlighting was available on the previous Thermapen.  It was an additional cost.  Intelligent backlighting is now standard in every Mk4.

cln_img_9733The Mk4 has some additional heft.  Here it is on my American Weigh Gram Scale.  The previous version weighed 94.63 grams.  The Mk4 comes in at 111.42 grams.  About 17 grams heavier.  My guess is that AAA batteries make up most of that difference.

cln_img_9760Here’s the Mk4 in an ice water bath in my newer Klean Kanteen Vacuum Insulated Growler.  This shows a couple things – First, it is reading 32 deg F.  Yay!  Second, you can see the rotating display in action.

cln_img_9750My favorite feature of the new Mk4… it is waterproof to the IP66/67 standard.  This is me running water on it in my utility sink.  You wouldn’t have caught me doing that with the previous version.

After using this thermometer for years, I can highly recommend it to you.  Thermoworks makes great gear and the Mk4 has lived up to expectations.
