Review: It’s reliable - Very good invention Review: Easy to read even from a distance - I can read the temperature on the unit from 20 feet away, that's good! I cannot comment on the alarm features for this device because I use this for my aquarium and so far have had no out of bounds temperatures. I would recommend this for your aquarium because aquarium heaters tend to fail. I lost about 25 fish when an old heater's thermostat broke in the on position and cooked all my fish ## Features - Precision source for calibrating process devices and measuring DC process signals - Oyster case with flip-up display is ideal for handheld or benchtop applications - Large 3-1/2 digit LCD display and touch keypad - Display readings in mA or as a percent of the 0 to 24mA range or as mV in voltage ranges - Provides adjustable 0 to 24mA and 0 to 10V calibration source ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DPB5HJ1 | | Additional Features | Alarm | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #223,774 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #88 in Weather Hygrometers | | Brand | Extech | | Brand Name | Extech | | Color | 401014A | | Connectivity Technology | Wired | | Customer Reviews | 4.2 out of 5 stars 13 Reviews | | Display Type | LCD | | Global Trade Identification Number | 00793950411148 | | Immersion Depth | 9.6 feet | | Included Components | 401014A | | Indoor Outdoor Usage | Outdoor | | Item Length | 9.6 feet | | Item Type Name | Big Digit In/Outdoor Thermometer w Alarm | | Item Weight | 4.8 ounces | | Manufacturer | Extech | | Model | 401014A | | Model Name | Big Digit In/Outdoor Thermometer w Alarm | | Number of Batteries | 1 AAA batteries required.
