The Uni-T UT303C+ non-contact infrared thermometer offers a wide measurement range of -32 to 1300 °C, a fast 250 ms response, and a circular laser that accurately marks the measured area. With a D:S ratio of 30:1, adjustable emissivity, and memory for up to 99 records with date and time, it is ideal for quick surface-temperature checks in industry, maintenance, and diagnostics.
The Uni-T UT303C+ is an advanced infrared thermometer for accurate non-contact surface temperature measurement. Compared to standard thermometers, a ring (circular) laser makes work easier by clearly outlining the entire measurement field—giving you better control over what you are actually measuring. A clear color EBTN display and ergonomic design speed up operation both on-site and in the field.
Thanks to the 30:1 distance-to-spot (D:S) ratio, you can measure from a greater distance while maintaining accuracy. The instrument supports measured-value analysis (MAX/MIN/AVG/DIFF), the HOLD function, and storing records in memory for up to 99 measurements including date and time. Visual and audible alarms are also included for quick evaluation of limit values.
The model meets CE and UKCA requirements and is designed for everyday use—including resistance to drops from up to 1 m. The package includes everything you need for immediate use.
