What Happens When You Put the World's Toughest Smartwatch in Liquid Nitrogen?
Diese Uhr wird hier als T Rex II bezeichnet und ist militärisch. Smartwatch mit Titan, Unibody- und Saphirglasscheibe, So ist es wasserdicht und es kann sogar negativ funktionieren 30 Grad Celsius. Lassen Sie uns also testen, wie stark ihr Saphirglas auf ihrem Bildschirm ist. Ill just grab this stone here and try to scratch the glass and nothing theres, no scratch at all. So this is really scratch resistant screen here, ziemlich beeindruckend. Alles klar, so first were going to do the liquid nitrogen test. So this is way below the recommended temperature that a maze fit says that you can use the watch. They recommend negative 30 degrees celsius as the lowest temperature, but were going way lower than that negative 196 Grad Celsius, thats negative 320 Grad, Fahrenheit. Okay, here we go three two one see how long till the screen goes out. Gut, its actually still on in there no way well its turning a weird color look at that you can see that the screen actually changed. Colors here now i know whats going on here, because ive done tests with led lights in a previous experiment, where i dip them in liquid nitrogen. So when you drop the temperature of led significantly, it actually shifts the light emitted towards the blue end of the spectrum and thats kind of exactly what we saw here. It looked more bluish and just had a faint blue glow to it. Okay, i dont see any light coming out of it now, while were waiting for this to get down to the liquid nitrogen temperatures, how cold is liquid, nitrogen well its so cold that liquid nitrogen actually condenses the oxygen out of the air? So if you just get a bag of liquid nitrogen liquid oxygen will just start forming around the bag, in fact its so cold thats carbon dioxide, the stuff you breathe out, actually becomes a solid.
This is the why stuff that you sometimes see floating on top of liquid nitrogen, also called dry ice. Okay, its been several minutes now, so this should be pretty close to liquid nitrogen temperatures. jetzt. Okay, lets see if this actually turns back on now. Okay, so this is negative 196 Grad Celsius. Das ist verrückt. Now this is a cold watch, looks like the liquid crystals are becoming solid again, so after we warmed it back up it wasnt turning on, but i just charged it for a bit and then it turned right back on after that. Schau dir das an, it works no way kind of made some cracks in the lcd, not the actual glass itself, but the liquid crystals below it, but other than that it works just fine, Das heißt, so cool so its nice to know. If you ever fall in a vat of liquid nitrogen, your watch will survive, but you probably wont now these cracks only form because we put it at negative 196 Grad Celsius. If you keep it above negative 30 Grad Celsius. That wont happen. So the watch held up to the liquid nitrogen, but lets see if its still waterproof or fluid proof, Okay, orange juice, about some vinegar. Okay, what about gasoline? Oh Mann, so look at that still works. Just fine like nothing. Auch, whats really cool about the t. Rex 2 is that its a smart watch that has dual band and 5 satellite high precision positioning, so you can go anywhere with it and track where youve been or where you need to go.
It also has route import and real time navigation on it. Its also passed 15 military standard toughness tests and also it has an ultra long day, battery life thats, nicht 24 Stunden, Das heißt 24 days of battery life with typical use, and i want to thank amaze fit for sponsoring this video.
