Review: Good price for what it is. - Nice little thermometer, I find that even though it's reading very accurate so far, it's a little hard to read as the marking are very small and so far with just over a month of use, it's only come unstuck once in the marine tank, but any I've had have done the same. Worth the money and so far, working well. Review: Basic & good choice - can’t go wrong - Traditional method that will not go wrong like a digital version. Digital versions have let me down in the past or been extremely inaccurate so I would just get one of these, pop them in and you can’t go wrong. Accurate when checked against other methods, value for money & stickiness can’t be beat even after 1+ years. The ease of installation is unbeatable and can even be done by five-year-old. Performance and durability again is unbeatable as one year on, performing as well as day one and is still in mint condition apart from a little bit of algae - still doing its thing! ## Features - Accurate and easy to read, it provides temperature readings in centigrade and fahrenheit. - It also has a safety zone temperature range indicator for most tropical fish. - For fresh or saltwater aquariums. - Model number: 11201 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002AQITK | | Age Range Description | Adult | | Brand | Marina | | Colour | Transparent | | Country Of Origin | China | | Customer Reviews | 4.5 4.5 out of 5 stars (17,733) | | Display Type | Analog | | Global Trade Identification Number | 00015561112017 | | Immersion Depth | 15 Centimetres | | Included Components | Marina Floating Thermometer for Betta Fish Tank with Suction Cup, Aquarium Thermometer, 11201A1 | | Indoor Outdoor Usage | Indoor | | Inner Material | Glass | | Item Length | 7 Inches | | Item Weight | 0.01 Kilograms | | Manufacturer | Rolf C Hagen UK Ltd | | Manufacturer Part Number | 11201A1 | | Model Name | 11201A1 | | Model Number | 11201A1 | | Outer Material | Glass | | Power Source | Battery Powered | | Product Care Instructions | Wipe Clean | | Resolution | 1°C | | Response Time | 500 Milliseconds | | Reusability | Rechargeable | | Special Features | Durable, Easy to Use, Underwater | | Style Name | Thermometer | | UPC | 015561112017 | | Unit Count | 1 count | | Upper Temperature Rating | 40 Degrees Celsius | ## Product Details - **Age range (description):** Adult - **Brand:** Marina - **Colour:** Transparent - **Display type:** Analog - **Included components:** Marina Floating Thermometer for Betta Fish Tank with Suction Cup, Aquarium Thermometer, 11201A1 - **Outer material:** Glass - **Power source:** Battery Powered - **Product care instructions:** Wipe Clean - **Special feature:** Durable, Easy to Use, Underwater - **Unit count:** 1 count ## Images ![(A1201) 4 inch Glass Thermometer - Image 1](https://m.media-amazon.com/images/I/81kPG87+wXL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good price for what it is. *by T***N on 29 December 2025* Nice little thermometer, I find that even though it's reading very accurate so far, it's a little hard to read as the marking are very small and so far with just over a month of use, it's only come unstuck once in the marine tank, but any I've had have done the same. Worth the money and so far, working well. ### ⭐⭐⭐⭐⭐ Basic & good choice - can’t go wrong *by G***L on 1 July 2024* Traditional method that will not go wrong like a digital version. Digital versions have let me down in the past or been extremely inaccurate so I would just get one of these, pop them in and you can’t go wrong. Accurate when checked against other methods, value for money & stickiness can’t be beat even after 1+ years. The ease of installation is unbeatable and can even be done by five-year-old. Performance and durability again is unbeatable as one year on, performing as well as day one and is still in mint condition apart from a little bit of algae - still doing its thing! ### ⭐⭐⭐⭐ Good back up thermometer, but very small *by M***L on 11 September 2025* The display is teeny tiny so pretty difficult to read, but I only use it as a back up thermometer in my tank, in case my digital thermometer goes crazy or runs out of battery. The positive is that the ‘safe’ water temperature area has a green background so it’s fairly easy to check that your water is in this zone, but to check the actual temperature you’d need a magnifying glass or a lot of patience --- ## 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.co.uk/products/48157718-a1201-4-inch-glass-thermometer](https://www.desertcart.co.uk/products/48157718-a1201-4-inch-glass-thermometer) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
