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 of 10:1, which means that the measurement spot is 10 times the distance from the sensor. This makes it ideal for measuring the temperature of large objects or objects that are far away.

The UT300B has a simple, one-button operation. To take a measurement, simply point the laser 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 current measurement so you can easily read it.

The UT300B is powered by a single 9V battery. It has an automatic power-off feature that turns off the unit after 15 minutes of inactivity to conserve battery life.

The UT300B comes with a carrying case, a user manual, and a test certificate.
