testo 735-2, temperature measuring instrument (3-channel)

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. 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.

testo 735-2, 3 channel temp. meas. instr., T/C Type K/T/J/S/Pt100, audible alarm, connection for max. 3 optional radio probes, with readings memory, PC software and USB data transmission cable, with battery and calibration protocol

1) According to standard 60751, the accuracies of Class A and B refer to -200 to +600°C (Pt100)
2) According to standard EN 60584-2, the accuracy of Class 1 refers to -40 to +1000°C (Type K), Class 2 to -40 to +1200°C (Type K), Class 3 to -200 to +40°C (Type K).
A probe always corresponds to only one accuracy class.
