Uni-t Ut300b: Pros And Cons, Common Issues, And Best Places To Purchase
Uni-T UT300B Information
The Uni-T UT300B is an infrared thermometer that measures temperatures from -18 to 380 degrees Celsius (-0.4 to 716 degrees Fahrenheit). It has a distance-to-spot ratio (D:S) of 10:1, which means that the measurement point is 10 times the distance from the front of the thermometer. The UT300B has a maximum measuring accuracy of ±2 degrees Celsius or ±2%, whichever is greater. It also has a repeatability of <±0.5 degrees Celsius or <±0.5%, whichever is greater. The response time is 500 milliseconds.
The UT300B has a simple one-button operation. To take a measurement, simply point the thermometer at the object you want to measure and press the button. The temperature will be displayed on the backlit LCD screen. The UT300B also has a data hold function, which allows you to freeze the displayed temperature so that you can read it more easily.
The UT300B is powered by a single 9V battery. The battery is located in the handle of the thermometer. The thermometer also has an auto power off feature that turns off the unit after 15 minutes of inactivity.
The UT300B comes with a carrying case, a user manual, and a 9V battery.
