The testo 720 is a robust temperature measuring instrument
for precise air, surface and immersion measurements in the
measuring range from -100 to +800 °C.
It is possible to connect Pt100 probes as well as NTC probes to the onechannel measuring instrument.
In combination with the TopSafe, the testo 720 is resistant
to aggressive media – as is the glass-coated probe, which
has proven its worth in daily laboratory work. You, as the user, can store limit values in the instrument
yourself; as soon as these upper or lower limits are violated,
an audible alarm sounds.
The instrument also continuously shows all minimum and maximum values in its large backlit display.
Using the optional Testo report printer, the
measurement results can be directly printed out on site as
