Testo 735-2 standard thermometer

Precise temperature measuring instrument with data record

The Testo 735-2 is robust and compact measuring instrument Testo 735 is universally applicable.

Precise temperature measuring instrument with measurement value store (10,000 values) PC software and USB data transfer cable.

The instrument has a probe input for highly accurate Pt100 probes and two inputs for fast thermocouple probes. The measurement values from up to three further temperature probes can be shown in the clear measuring instrument display wirelessly, i. e. using measurement data transfer by radio. A system accuracy of 0.05°C at a resolution of 0.001°C is achieved using the highly accurate plug-in Pt100 immersion/penetration probe.


The measurement system is thus ideal for use as a working standard. Selectable user profiles, i.e. programming of the buttons adapted to the application, enable intuitive and fast operation.

  • Highest precision over the entire measuring range thanks to system adjustment
  • System accuracy up to 0.05°C
  • Display, storage and print-out of Delta T, min., max. and mean values
  • Audible alarm (adjustable limit values)
  • Cyclic printing of measurement values, e.g once per minute
  • Protection class IP65
  • Certified according to EN 13485

Applications

Measurement of the heating of electronic components

Calibration of stationary temperature probes

Measuring temperature in a chemical laboratory
