Review: Good Thermometer - Very good thermometer. Accurate and cute. I use it for Room temperature and Air-conditioning cooling check. Ivcompared with google weather and other thermometer, found accurate. Few things to note 1. Button batteries 2. No backlight 3. Always on and No On/Off switch Review: Good Product - Positive points: 1. Build quality is very good specially for this price tag. 2. It workes very well and gives temperature readings with +-1 error which is very good. Negative points: 1.There is no such ON and OFF key therefore you have to consider this before buying this...for me this not the issue. 2. Temperature increases and decreases slowly when it is subjected to reading things. Overall I wound say this is must buy product in this price tag. ## 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 | | 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 3,716 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.
