Key Features

It combines advanced features, superior durability, and user-friendly operation to deliver reliable, precise temperature measurements across various industrial and laboratory settings.

  • Advanced Display: Multilingual large dot matrix LCD with clear text and wide viewing angles, equipped with backlight for easy readability in any lighting condition.
  • Intuitive Functions: Includes HOLD function to freeze readings and REL feature to display relative measurements, supporting °C, °F, and K units.
  • Dual Measurement Capability: Supports two thermocouple probes simultaneously and calculates the difference between channels for enhanced versatility.
  • Configurable Alarms: Customizable thresholds with visual LCD alerts and buzzer activation for immediate notification of out-of-range values.
  • Large storage capacity: up to 1 million data, file system based.
  • The logged data are store in CVS files that can be easily viewed connecting the instrument to a PC via USB: the instrument is seen by the PC as a mass storage device, the data can be read oud and evaluated without software necessarily needed.
  • Automatic log with configurable interval.
  • The instruments integrate a Real Time Clock: date and time of each logged sample are stored.

Applications and Benefits

This precision thermometer is ideal for demanding industrial, laboratory, and maintenance applications where accuracy and reliability are critical. Its broad compatibility with standard thermocouple types (K, J, T, N, R, S, B, and E) allows tailored temperature measurement across various materials and processes.

Thanks to its rugged design and ergonomic form factor, the PRO 135.2 offers shock resistance and ease of handling, making it suitable for continuous use in challenging environments.
