testo 735 – Multichannel thermometer
Product Description
The robust and compact measuring instrument testo 735 is universally applicable and is available in two versions:
testo 735-1: Precise temperature measuring instrument without measurement value store
testo 735-2: 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.
