V-Shaped, Dual-Scale, Mercury-Free Thermometers for Indoor Science Use (Pack of 10)

We bought these for a science fair experiment. They were sturdy, well-designed thermometers. They also, when tested, were all within 1-2 degrees of each other, making them highly effective. This is a great price for a product that functions. Highly recommended for a science fair where multiple thermometers or needed or for a classroom where multiple children need a thermometer.

These thermometers were inexpensive and extremely responsive. They detect temperature changes of a few degrees almost instantly. They worked well for my baking soda and vinegar lab with my 5th graders, and I highly recommend these to any other teacher!

We have used a few of these for simple science experiments. The thermometers are decently small and seem to be quality for the price point. They can be multi use, so I would say they are pretty durable. I have never had one break or leak. The readings are a little slow to register, and I am not sure how precise they are; but they get the job done for elementary science class. I would purchase again- but I don’t think I will have to. The box I bought has a bunch.

Needed to check temps in several locations in two buildings. First I set them out near my desk and after 24 hours saw that readings were identical on all ten. Then I compared two to another thermometer near a thermostat, and that one was about a degree off. Range is important as alochol thermometers generally will not be linear and slight adjustment of the scale is required. Here we were talking approximately room temperature and they are fine.

The ones that worked did a good job in my science class. The problem is that was only about 1/3 of them that did work. They had air bubbles or just did not show a temperature change.

After reading reviews and descriptions of thermometers for 6 weeks we chose these and have been pleased overall. They have been used many times in the last 6 months for experiments in the classroom. Before we begin an experiment we read the temperature on them and choose those with the same temp as they do not always read the same though they are usually close. They are quite sensitive so do not hold them while reading the initial temp as your body temp can affect it. I'm very pleased with the product for the price. Only improvement suggested is that they somehow are assembled to read the same temperature.

Does it's job, you get what you play for. I used this to measure temperature in a bunch of rooms after a duct install. They are small and the temperature is hard to read.

These are exactly what we needed for my daughter's 6th grade compost project. They are durable, easy to clean, and show both celsius and fahrenheit readings. Thank you!
