Learn. 2 00:00:04.000 --> 00:00:07.750 Measuring temperature is a common lab activity for students, 3 00:00:07.750 --> 00:00:12.000 and Vernier has several different ways of being able to do this. 4 00:00:12.000 --> 00:00:14.750 One of our most popular probes is 5 00:00:14.750 --> 00:00:16.750 our Stainless Steel Temperature Probe. 6 00:00:16.750 --> 00:00:19.000 And, it covers most temperatures that you 7 00:00:19.000 --> 00:00:21.000 probably would use in the classroom. 8 00:00:21.000 --> 00:00:25.000 Going to do melting of ice, or boiling of water, or whatnot. 9 00:00:25.000 --> 00:00:27.500 You can put this in different acids, you can do that. 10 00:00:27.500 --> 00:00:32.250 So, it's one of the reasons it used very commonly in the labs. 11 00:00:32.250 --> 00:00:33.750 But, we have some other choices. 12 00:00:34.750 --> 00:00:37.250 Next is the Wide Range Temperature Probe. 13 00:00:37.250 --> 00:00:40.500 And, the key feature for this one is the fact that it can go to a 14 00:00:40.500 --> 00:00:44.500 higher temperature than our stainless steel temperature probe. 15 00:00:44.500 --> 00:00:48.000 So, the idea is that you might be using this in an organic lab, 16 00:00:48.000 --> 00:00:50.000 and you need to go up to temperatures as high as 17 00:00:50.000 --> 00:00:53.000 330 degrees Celsius, this one can do this. 18 00:00:53.000 --> 00:00:56.500 It's also, obviously, physically larger, and it's designed to have 19 00:00:56.500 --> 00:01:00.000 the same size shaft as a standard alcohol thermometer. 20 00:01:00.250 --> 00:01:04.000 Next would be the Surface Temperature Sensor. 21 00:01:04.000 --> 00:01:07.000 And, this one has a very fine wire, 22 00:01:07.000 --> 00:01:09.750 that is very responsive to temperature. 23 00:01:09.750 --> 00:01:14.000 So, its response time is much faster than 24 00:01:14.000 --> 00:01:16.750 some of the other sensors and probes. 25 00:01:16.750 --> 00:01:19.000 You could tape it to your skin. 26 00:01:19.000 --> 00:01:21.000 And so, it just gives you some options 27 00:01:21.000 --> 00:01:24.000 of other ways of measuring temperature. 28 00:01:24.500 --> 00:01:28.750 Next is the Go!Temp, and this is a temperature sensor 29 00:01:28.750 --> 00:01:32.750 that plugs into the computer via the USB port. 30 00:01:32.750 --> 00:01:35.500 So, the other ones that we've seen actually would 31 00:01:35.500 --> 00:01:38.250 go into one of our data loggers, like a LabQuest 2, 32 00:01:38.250 --> 00:01:40.750 or a LabQuest Mini, or something like that. 33 00:01:40.750 --> 00:01:44.500 This, you actually plug into the computer, the USB port. 34 00:01:44.500 --> 00:01:48.750 And, it's very similar to our Stainless Steel in terms of its ranges. 35 00:01:48.750 --> 00:01:50.750 But, it just gives you that ability to do that. 36 00:01:50.750 --> 00:01:52.750 And it's an inexpensive way to get started 37 00:01:52.750 --> 00:01:54.250 if you already have a computer. 38 00:01:54.750 --> 00:01:58.000 Next would be the Easy Temp. 39 00:01:58.000 --> 00:02:01.000 And, this is a temperature sensor that plugs into 40 00:02:01.000 --> 00:02:05.250 the TI devices, the TI-Nspire, or TI-84 calculator. 41 00:02:05.250 --> 00:02:08.750 So, it has a miniUSB port, that's there. 42 00:02:08.750 --> 00:02:13.250 Now, it turns out that the Easy Temp and the Go!Temp, 43 00:02:13.250 --> 00:02:16.250 are actually very similar electronically. 44 00:02:16.250 --> 00:02:19.500 The main difference is the size of the USB ports. 45 00:02:19.500 --> 00:02:23.000 And, we do sell adapters that allows you to make the 46 00:02:23.000 --> 00:02:26.750 Go!Temp into an Easy Temp, or vise versa. 47 00:02:26.750 --> 00:02:30.000 And so, it's really just the difference in the size of that. 48 00:02:30.000 --> 00:02:32.750 So, depending on what device you have, if you have a TI device, 49 00:02:32.750 --> 00:02:36.500 you probably would go with the Easy Temp for that. 50 00:02:37.000 --> 00:02:40.750 Next would be the Infrared Thermometer. 51 00:02:41.000 --> 00:02:43.750 This allows me to measure temperatures of an object 52 00:02:43.750 --> 00:02:45.750 without having to touch it. 53 00:02:45.750 --> 00:02:48.750 All of these other sensors and probes have to be in contact 54 00:02:48.750 --> 00:02:51.000 with what it is your going to measure the temperature. 55 00:02:51.000 --> 00:02:54.000 This one actually measures the temperature via 56 00:02:54.000 --> 00:02:56.750 the infrared radiation coming from the object. 57 00:02:56.750 --> 00:02:59.000 And so, the radiation comes in here, 58 00:02:59.000 --> 00:03:01.750 and you get the temperature reading. 59 00:03:01.750 --> 00:03:07.000 And then lastly, would be the Extra Long Temperature Probe. 60 00:03:07.000 --> 00:03:09.750 And so, it's the sensor here. 61 00:03:09.750 --> 00:03:13.750 And, the main difference with this one is the length of the cord. 62 00:03:13.750 --> 00:03:16.250 This one is used sometimes to measure, say, 63 00:03:16.250 --> 00:03:18.250 the temperature profile of a pond. 64 00:03:18.250 --> 00:03:19.750 Or, you want to measure the temperature 65 00:03:19.750 --> 00:03:22.000 on the roof of the school without having to go up there. 66 00:03:22.000 --> 00:03:25.750 So, you could put this up there, and be able monitor it that way. 67 00:03:25.750 --> 00:03:28.000 So, there are a lot of different options for 68 00:03:28.000 --> 00:03:30.750 being able to measure temperature. 69 00:03:30.750 --> 00:03:33.250 So, you can check our catalog or our web site, 70 00:03:33.250 --> 00:03:35.750 and see which one is correct for you.
