Product Description

The testo 526-1 is a high-precision differential pressure measuring instrument with an internal sensor and a measuring range from 0 to +2,000 hPa. It can calculate the differential pressure to an accuracy of ± 0.1% of final value.

Additional probe inputs for versatile measurements with the differential pressure measuring instrument

Up to two probes (optional) can also be attached via freely assignable probe inputs. You have the choice of a comprehensive range of probes for this:

Differential pressure probes
Absolute pressure probes
Relative pressure probes
Temperature probes, such as surface, immersion and penetration probes

Further advantages of the testo 526-1 high-precision differential pressure measuring instrument

The integrated test menu in the testo 526 enables seamless recording, especially for tightness testing on containers. To document the pressure test, there is an option enabling the measurement data to be processed and archived using software and/or printed out via the testo fast printer directly on site (software and printer available to order separately).

The memory can record up to 25,000 readings. These are stored under their individually designated measuring locations (max. 99 measuring locations) which means they can be quickly found again. Measurement data can be saved individually or as a series of measurements. The measuring rate (0.04 seconds, 1 second to 24 hours) and the number of values to be stored can be freely selected.
