When I went to feed my fish I could see 68 on this gauge. I bought this gauge From a forum recommendation and I put this gauge on my 3 aquariums. Because of that I could visually see that the Cube's water temp had dropped. When I opened the door to my Cubes stand I saw that the Heater was unplugged. I unplugged it while doing a water change and then I forgot to plug it back in.when I was done. One of the best things I have done for my aquariums was to add this stick on temp as a visual backup, so I can better monitor my aquariums TEMP at a glance! This large stick on gauge (easy to see temp) saved me that morning. This weekend outside temps are supposed to be in the 30's so the water could have gotten even colder. This gauge IS my Visual Backup! It matches the temp on my Heater and internal glass thermometer so I trust it. So far so good month's later. If it changes it's reliability I will report back. I give it 2 thumbs up! Review: Great exterior aquarium thermometer! - I really like the way this thermometer looks and works. Quickly adjusts to reflect the water temperature virtually immediately after it's applied to the tank. My favorite feature is that it's very easy to read. This is because not only are the size of the individual temperature indicator blocks and the brightness of the associated background colors perfect, but the numbers representing the temperature are crisp, black, and appear right inside the color blocks. Visually striking and extremely easy to read. And it's moveable! Good aquarium thermometer at a reasonable price point. ## Features - Easy To Read - Mounts Vertically On The Outside Of Your Aquarium - Easily Movable - Country of Origin: CHINA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00ZZR1OW6 | | Additional Features | Non-Contact, Waterproof | | Age Range (Description) | All Life Stages | | Age Range Description | All Life Stages | | Best Sellers Rank | #31,656 in Pet Supplies ( See Top 100 in Pet Supplies ) #28 in Aquarium Thermometers | | Brand | LCR Hallcrest | | Brand Name | LCR Hallcrest | | Color | Black | | Customer Reviews | 4.5 out of 5 stars 2,150 Reviews | | Display Type | Analog | | Global Trade Identification Number | 00034637309724 | | Included Components | LCR Hallcrest 43330972: Liquid Crystal Aquarium Thermometer Vertical | | Indoor Outdoor Usage | Indoor | | Item Length | 6.75 Inches | | Item Type Name | LCR Hallcrest 43330972: Liquid Crystal Aquarium Thermometer Vertical | | Item Weight | 0.02 Pounds | | LowerTemperature Range | 66 Degrees Fahrenheit | | Manufacturer | LCR Hallcrest LLC | | Model | 43330972 | | Model Name | LCR Hallcrest 43330972: Liquid Crystal Aquarium Thermometer Vertical | | Outer Material | Plastic | | Part Number | 43330972 | | Power Source | Battery Powered | | Product Care Instructions | Wipe Clean | | Response Time | 500 Milliseconds | | Reusability | Reusable | | Special Feature | Non-Contact, Waterproof | | Specification Met | CE, FCC | | Style Name | Functional | | UPC | 034637309724 786714023404 | | Unit Count | 1 Count | | Upper Temperature Range | 84 Degrees Fahrenheit | ## Product Details - **Brand:** LCR Hallcrest - **Special Feature:** Non-Contact, Waterproof - **Color:** Black - **Age Range (Description):** All Life Stages - **Included Components:** LCR Hallcrest 43330972: Liquid Crystal Aquarium Thermometer Vertical - **Outer Material:** Plastic - **Specification Met:** CE, FCC - **Display Type:** Analog - **Product Care Instructions:** Wipe Clean - **Unit Count:** 1 Count ## Images ![LLC 43330972: Liquid Crystal Aquarium Thermometer Vertical - Image 1](https://m.media-amazon.com/images/I/91yrhxhgAGL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's reliable with large temp degrees to see. *by B***B on January 30, 2026* Temps where I live has dipped into the 50's I left my sliding door open about 4 inches so my living room where my Oceanic BioCube sits got chilly.
