Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology. ## Features - Measure a wide range of temperatures with these thermometers specially designed for student safety - Features dual-scale temperature readings from -22°F to 240°F and -30°C to 120°C - Mercury-free & recessed glass tube for safe classroom use - Thermometers measure 6 ¾" in length - 10 thermometers per pack ## Technical Specifications | Specification | Value | |---------------|-------| | Units | 10.0 Count | | Brand | hand2mind | | Age Range Description | Adult | ## Product Details - **Brand:** hand2mind - **Special features:** High Accuracy - **Age range (description):** Adult - **Outer material:** Glass - **Display type:** Analog ## Images ![ETA High-Range, Dual-Scale, Mercury-Free, Safety Thermometers for Indoor Science Use (Pack of 10) - Image 1](https://m.media-amazon.com/images/I/61icjw2NvQL.jpg) ## Customer Reviews ### ⭐ Doesn't work *by J***O on Reviewed in Canada on 14 July 2022* They dont work. ### ⭐⭐⭐⭐⭐ good *by P***C on Reviewed in Canada on 15 August 2018* good ### ⭐⭐ Precise but not accurate, poor construction *by A***N on Reviewed in Canada on 17 December 2020* tl;dr: two thermometers may read as much as 14 degrees off; about half of them are very difficult to read because the actual thermometer and the scale are misaligned; one of them warped significantly in 90°C water.This is probably a good case of "you get what you pay for" as these thermometers were purchased because they were cheap and would arrive before classes go home for winter break. I have significant issues, but if you, like me, just need thermemeters immediately, they are technically thermometers that you can get on short notice on a budget.1. Readings: I bought these specifically for an insulated container experiment, where my students used household materials to insulate a jar. Water was poured from a kettle into the containers, left for three minutes, and the initial readings varied widely (from 96°C to 77°C). Accepting that this was in different vessels, I repeated the test using only two vessels, with five thermometers (and an actual glass scientific thermometer) in each one. Both glass thermometers registered over 90°C (91°C and 92°C) after three minutes. The purchased thermometers varied from 94°C to 80°C.2. We were measuring cooling rates, and the thermometers seem to measure change more precisely than actual temperature. I.e, a change of 10°C on one thermometer from this set is also registered as a change of 10°C on another thermometer from this set.3. One thermometer is significantly warped to the point that the plastic around the bulb is bent and I'm worried the thermometer will crack. I only gave the thermometers a cursory inspection upon arrival, but none of them were warped significantly. The plastic is bent, in terms of straightness, but also in terms of the shelf that the bulb sits on.4. These thermometers have a ribbon of spirits that indicates the temperature, but four of my thermometers have the glass tube oriented in such a way that to see the ribbon effectively (with any kind of width showing), I have to turn the thermometer so that it is difficult to read the scale. I will probably try to fix this by twisting the glass tubes, but given the construction, I think they are likely to break. ## Frequently Bought Together - hand2mind High-Range, Dual-Scale, Mercury-Free, Safety Thermometers for Indoor Science Use (Pack of 10) - Teenitor Graduated Cylinder Plastic Beaker, 5pcs Plastic Graduated Cylinder 10ml 25ml 50ml 100ml 250ml and 5pcs Plastic Beakers 50ml 100ml 250ml 500ml1000ml Clear 10pcs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/292732879-eta-high-range-dual-scale-mercury-free-safety-thermometers-indoor](https://www.desertcart.sn/products/292732879-eta-high-range-dual-scale-mercury-free-safety-thermometers-indoor) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-10*
