The testo 735-1 is a robust and compact measuring instrument, with a probe socket for highly accurate Pt100 probes, and two sockets for fast-action thermocouple probes. Readings from up to three additional temperature probes can be shown on the instrument's clear display; measurement data transmission is by radio, or wireless. A total of six channels can be collected in this way by the instrument. Using the highly accurate, plug-in Pt100 immersion / penetration probe, a system accuracy of 0.05 °C with a resolution of 0.001 °C is reached. This measurement system is therefore ideally suited for use as a working standard. Data measured by testo 735-1 can be transmitted by infrared to the Testo printer for documentation purposes. If cyclical printing is used, it is also possible to print data on the printer once every minute, for example. The Testo 735-1 can be used in a variety of different applications, including: • Measurement of the heating of electrical components • Calibration of stationary temperature probes • Measuring temperature in a chemical laboratory • Temperature measurement in the cosmetics industry • Temperature distribution in refrigerators and conditioning cabinets
