Review: Good product - I use last 17 months it working good Review: Worked really well for 8 months - Inspite of its short lifespan, I still rate this 4 stars because of the outstanding value it offers (at least for me). 180 bucks for 8 months is around 20 bucks a month. Can I afford to spend 20 bucks a month? Yes I don't mind. I have two aquariums and bought two of these thermometers. Simple to use and pretty accurate. One of them is still working fine but the other has done wonky now. The temperature readings are off the charts. I have tried testing it in multiple environments with varying temperatures but in vain. Rest In Peace dear thermometer !! Winter is coming and this season is crucial for aquarium hobbyists. so I will buy another one. ## Features - ✅ High Accuracy Temperature Sensor Provides accurate readings with ±1°C tolerance for reliable temperature monitoring. - ✅ Wide Temperature Measurement Range Measures from -50°C to +70°C, perfect for fridges, deep freezers, coolers, and aquariums. - ✅ External Wired Probe (80 cm) Long wired sensor allows easy placement inside appliances while display remains outside. - ✅ Easy-to-Read LCD Display Large digital display with 0.1°C resolution for clear visibility anytime. - ✅ Durable & Lightweight Design Compact ABS plastic body, moisture-resistant and easy to install anywhere. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07CJY5C92 | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #38,395 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #2 in Refrigerator Thermometers | | Brand | R-TEK | | Brand Name | R-TEK | | Colour | black | | Connectivity Technology | fridge thermometer, Aqurium thermometer, room thermometer, water tank tempreture thermometer. | | Country of Origin | India | | Customer Reviews | 3.8 out of 5 stars 3,718 Reviews | | Display Type | fridge thermometer, Aqurium thermometer, room thermometer, water tank tempreture thermometer. | | Immersion Depth | 80 Centimetres | | Included Components | 1 Thermometer | | Indoor Outdoor Usage | Indoor | | Item Length | 10 Centimetres | | Item Weight | 80 Grams | | Manufacturer | Raj themometer | | Model Name | DIGITAL FRIDGE THERMOMETER | | Model Number | RT-116 | | Number of Batteries | 2 LR44 batteries required.
