The UNI-T UT305A+ measures infrared temperatures from -50°C to 1850°C and supports K-type thermocouple, ambient temperature, relative humidity, dew point and wet-bulb measurements. Its 55:1 distance ratio, professional measurement modes and 999-reading storage make it suitable for industrial thermal inspection and process monitoring.

Key Features

  • High-Temperature Measurement – Measures non-contact infrared temperatures from -50°C to 1850°C.
  • Multiple Environmental Parameters – Measures ambient temperature, relative humidity, dew point and wet-bulb temperature.
  • Contact Temperature Input – Supports K-type thermocouple measurements from -50°C to 1370°C.
  • Professional Measurement Modes – Includes infrared, heat conduction, dew point and surface temperature comparison modes.
  • Data Recording – Stores 999 groups and outputs measurement data in PDF or CSV format through USB Type-C.
