Run a browser in fullscreen without any other UI elements (like translate, restore session, e.t.c.)
You should be able to add the two flags
--disable-translate and --incognito
chromium-browser --disable-translate --kiosk --incognito http://192.168.1.23/monitor.html
Incognito mode is a funny way to make Chromium not worry about the last session when it restores from a crash.

(putting this as answer because i cant comment)
As of chromium version 60.0.3112.89, --disable-translate doesn't work anymore.
The workaround, if you have access, is to remove the lang from html tag or set it to "en".
As of version 69, the previous workaround doesn't work anymore, the solution is to add this tag to the html head:
<meta name="google" content="notranslate">
